p. 3 |
Dilip Kumar Mishra, Shikha Taneja, Vivek Singh, Uppala Veena, Swathi Kaliki DOI:10.4103/IJPM.IJPM_1313_20 PMID:35074957
Background: Ocular surface squamous neoplasia (OSSN) comprises neoplasm arising from the ocular surface, which includes conjunctiva, cornea, and limbus and ranges from mild dysplasia to invasive squamous cell carcinoma. Purpose: The aim of this work was to study the spectrum of OSSN based on histopathological analysis. Materials and Methods: This was a retrospective cross-sectional study comprising 776 histopathologically diagnosed cases of OSSN from January 2004 to December 2014. Results: The mean age of presentation of OSSN was 45 years (median, 45 years; 2 to 87 years) with male preponderance (74%). The most common age group of presentation was 41–60 years (n = 299; 39%). The most common type of OSSN was invasive squamous cell carcinoma seen in 50% (n = 383) eyes followed by severe dysplasia/carcinoma in situ in 31% (n = 250) eyes. Tumor infiltration at base was seen in 16% (n = 124), positive margins in 32% (n = 248), scleral infiltration in 14% (n = 109), intraocular extension in 3% (n = 23), and orbital extension in 4% (n = 26) eyes. OSSN was associated with actinic keratosis in 21% (n = 165) cases. Conclusion: Based on histopathology, invasive squamous cell carcinoma is the most common form of OSSN in the Asian Indian population.

Immunohistochemical expression of cyclooxygenase-2 in oral lichen planus and normal oral mucosa  |
p. 8 |
Tibin K Baby, PR Bindhu, Rekha Krishna Pillai, P Jayanthi DOI:10.4103/IJPM.IJPM_1304_20 PMID:35074958
Background: Oral lichen planus (OLP) is a chronic inflammatory disease for which the pathogenesis is complex and not fully understood; autoimmunity has been suggested as a causative factor. World health organization (WHO) has classified OLP as a potentially malignant lesion. Cyclooxygenase-2 (COX-2) is an inducible key enzyme that generates prostanoids which play a critical role in inflammation, immunopathology; also considered as a malignant potential marker. Aims: The present study was conducted to analyze and compare epithelial COX-2 expression in OLP clinical subtypes and normal oral mucosa to evaluate its role in the pathophysiology of the disease process. Methods: This retrospective immunohistochemistry (IHC) study was performed on tissue sections of 30 OLP and 10 normal oral mucosae for COX-2 expression. Statistical Analysis Used: Descriptive and comparative statistical methods were done using 'one-way Analysis of Variance (ANOVA), 't' and Chi-square tests. Results: All the OLP showed epithelial COX-2 expression; strong expression was noted in 80% of the OLP while normal oral mucosa sections showed no expression. Cox-2 expression was significantly higher in erosive lichen planus compared to reticular lichen planus. Conclusions: Strong expression of COX-2 in OLP suggested its important role in pathogenesis. Although COX-2 has been connected to malignant development and autoimmunity, as the malignant development in OLP is quite rare, this study suggests that increased levels of COX-2 seen here may support an autoimmune cause of the disease process.

Imaging and pathological discordance amongst the plethora of breast lesions in breast biopsies  |
p. 13 |
B Archana, Bhawna Dev, Suresh Varadarajan, Leena Dennis Joseph, MC Sheela, V Pavithra, Sandhya Sundaram, Jai Prakash Srinivasan DOI:10.4103/IJPM.IJPM_1209_20 PMID:35074959
Introduction: Imaging-guided breast tissue biopsy has become an acceptable alternative to open surgical biopsy for nonpalpable breast lesions. Discussion of abnormal results of the correlation between imaging and pathological findings can be very challenging as it can assist in decision-making with regard to the further treatment options by arriving at a comprehensive diagnosis. Materials and Methods: This was a retrospective study. Radiological data from imaging-guided breast biopsies of 500 patients during a 6-year period was collected and classified by a specialist radiologist as per the BI-RADS format. Histopathology reports were studied and discordance analyzed. Results: A total of 500 cases were reviewed. Approximately 33% (168) cases fell into the BI-RADS 3 category, 24.4% (122) into the BI-RADS 4, and 37% (187) into BI-RADS 5 categories. Approximately 50% (n = 250) cases were benign, 2.6% (13) belonged to the high-risk category, and 47.4% (237) were malignant. The number of discordant cases was 12 (2.4%), mostly due to technical factors. Sensitivity of biopsies to detect malignancy was 85%, specificity was 96%, and accuracy of biopsy in diagnosing cancer was 90%. Discussion: The "triple assessment" is the most sensitive method for detecting early breast cancer. An effective communication pathway must be established between a clinician, radiologist, and pathologist for surgical excision in discordance as it carries a high prevalence of carcinoma in these lesions. Conclusion: In discordant cases, either due to abnormal results of imaging or of abnormal pathological findings, the final decision is based on two concordant findings, out of the three parameters. This involves a multidisciplinary breast conference and an active participation by the pathologist.

p. 18 |
Md Ibrahim Siddiqui, Anita A Mahanta, SR Umesh, Saara Neeha, Sainath K Andola DOI:10.4103/IJPM.IJPM_1203_20 PMID:35074960
Background and Objectives: This research study has been carried out to study the various morphological changes in the heart in medicolegal autopsies and to compile data for the frequency of heart diseases found in autopsy cases. Methods: The present study comprised 430 medicolegal autopsy cases. Details of the cases were entered in a proforma prepared for the study. The heart was fixed in 10% formalin, and then, opened along the flow of blood. The findings were based on gross and microscopic examinations. Results: Out of 430 adult hearts, 211 (49.0%) cases showed 253 cardiac lesions; 35 (8.1%) cases of coronary atherosclerosis and 196 (45.5%) aortic atherosclerosis were noted; 7 cases of ischemic lesions (1.6%) were identified; 12 (2.7%) cases of hypertrophy; 2 cases of valve calcification; and 1 of cardiomyopathy were noted. Conclusion: In the present study, among medicolegal autopsies, atherosclerotic disease was the most frequently encountered lesion followed by hypertrophy. The incidence of atherosclerosis was found to be 47.6%. This study shows the high prevalence of atherosclerosis in the population.

Prevalence and risk factors of Helicobacter pylori infection in military personnel: a systematic review and meta-analysis |
p. 23 |
Chunmei Wang, Jun Liu, Yang An, Dan Zhang, Rui Ma, Xiaozhong Guo, Xingshun Qi DOI:10.4103/IJPM.IJPM_1084_20 PMID:35074961
Background and Aims: Helicobacter pylori infection is prevalent and recognized as a major cause of gastrointestinal diseases in the world. Previous studies on the prevalence of H. pylori infection in military personnel have shown some conflicting results. This study aimed to estimate the pooled prevalence of H. pylori infection and evaluate its risk factors in military personnel. Methods: The PubMed, EMBASE, and Cochrane Library databases were searched. We pooled the prevalence of H. pylori infection in military personnel using a random-effect model. Metaregression analysis was used to explore the sources of heterogeneity. Pooled proportion of H. pylori infection with 95% confidence interval (CI) was calculated. Results: Sixteen studies were included. Meta-analysis showed that the overall prevalence of H. pylori infection was 32% (95% CI = 31–33) in military personnel. There was a significant heterogeneity. Metaregression analysis showed that study region (P = 0.0004) and publication year (P = 0.023) were the potential sources of heterogeneity. In the subgroup analysis by study region, the highest prevalence was found in Asia (50.2%; 95% CI = 49–51.4). In the subgroup analysis by diagnostic methods for H. pylori, the highest prevalence was found when urea breath test was employed (47.9%; 95% CI = 46.5–49.3). The most common risk factor for H. pylori infection was familial aggregation, followed by living environment and age. Conclusion: H. pylori infection is common in military personnel. In future, we may require appropriate population screening for H. pylori infection by multiple diagnostic tests and increase the knowledge and awareness of the bacterial transmission among military personnel.

Immunoexpression of PTEN, HER2/neu, and Ki-67 in endoscopic gastric carcinoma biopsies; their correlation with histological subtypes and one-year survival |
p. 29 |
Seema Acharya, Brijesh Thakur, Richa Mittal DOI:10.4103/IJPM.IJPM_299_20 PMID:35074962
Background: Gastric carcinoma is a major cause of cancer-related morbidity and mortality worldwide. Gastric neoplasms arise from genetic and epigenetic changes in various genes. Present study evaluates the immunoexpression of PTEN, HER2/neu, and Ki-67 in endoscopic gastric carcinoma biopsies and correlates the expression of these proteins with clinicopathological features. Material and Methods: Adequate endoscopic biopsies of 27 cases of gastric carcinoma were evaluated for World Health Organization (WHO) and Lauren's classification subtypes along with HER2/neu, PTEN, and Ki-67 immunoexpression. HER2/neu immunostaining was scored as proposed in the Trastuzumab for gastric cancer (ToGA) trial while PTEN staining and downregulation were assessed using an immunoreactive score. The cut-off for Ki-67 expression was taken as 90th percentile of the values in adjacent non-neoplastic tissue. All statistical analysis was done at 5% level of significance with SPSS v22 statistical software. Results: Tubular adenocarcinoma was the commonest WHO histological subtype and 56% of cases were of intestinal type as per Lauren's classification. 55.6% of cases showed a complete loss of PTEN expression in neoplastic tissue. 17 of the 19 cases with adjacent non-neoplastic tissue showed PTEN downregulation in neoplastic tissue. 81.5% of cases had a high Ki-67 index and HER2/neu overexpression was noted in 36% of cases. All the four cases who died had high Ki-67 proliferation indices; 3 patients had loss of PTEN expression and HER2/neu overexpression. Conclusion: We conclude that these immunomarkers can play important role in the behavior of gastric carcinomas and can be targeted for new therapies.

Expression of HER2/neu in gastric adenocarcinoma and its correlation with serum HER2/neu level and E-cadherin expression |
p. 35 |
Ishan Pandey, Vatsala Misra, Aprajita T Pandey, Amita Verma DOI:10.4103/ijpm.ijpm_133_21 PMID:35074963
Aim: To assess HER2/neu expressions and correlate with E-cadherin and Serum HER2 level in gastric carcinoma. Method: 31 gastric biopsies and 1 resected specimen were taken in the study with patient details and stained with H and E for histopathological details following Lauren's classification. Immunohistochemistry for HER2 and E-cadherin expression was conducted followed by serum HER2/neu ELISA. Result: Adenocarcinoma with 61% diffuse, 29% intestinal, and 10% other type were observed with predominant HER2 immunoexpression in intestinal-type than in diffuse-type adenocarcinoma. Other observations marked 44% as 3+/positive and 56% as 2+/equivocal in intestinal type while 26% cases as 3+/positive, 69% as 2+/equivocal, and 1% as 1+/negative were observed in diffuse type. The data presented 33% membranous positivity and 67% both membranous + cytoplasmic positivity in intestinal type while 2% showed membranous positivity, 47% both membranous + cytoplasmic, and 42% only cytoplasmic positivity in diffused type. On comparing the localization pattern of HER2 and E-cadherin, 25% of cases showed membranous staining while 50% of cases showed membranous with cytoplasmic staining for both. No cytoplasmic HER2 staining as well as no any staining for E-cadherin was shown by 6% cases. Conclusion: Thus, it can be concluded that cytoplasmic expression of HER2 in gastric adenocarcinoma (mainly diffuse type) may be due to shedding of its extracellular domain, leading to loss of membranous E-cadherin expression on immunohistochemistry. The loss of membranous expression of E-cadherin and increased serum HER2 ELISA were correlated well with these findings.

Differential expression of CK7, CK20, CDX2 in intestinal and pancreatobiliary types of preriampullary carcinoma |
p. 42 |
Udayagiri D Sree, Aruna K Prayaga, V Venkat R. Reddy, N Rukmanghadha, Amit K Chowhan, BV Phaneendra DOI:10.4103/IJPM.IJPM_1440_20 PMID:35074964
Context: Incidence of periampullary carcinoma is low, approximately 0.5–2% of all gastrointestinal malignancies. Histologic subtyping has a prognostic bearing. The purpose of this study is to differentiate periampullary carcinomas based on immunohistochemistry (IHC) by using cytokeratin 7 (CK7), cytokeratin 20 (CK20), caudal type homeobox 2 (CDX2). Aims: To analyze the usefulness of IHC as single/panel of markers that included CK7, CK20, and CDX2. Settings and Design: This was a prospective study done from January 2017 to September 2018. Subjects and Methods: A total 50 pancreaticoduodenectomy specimens were evaluated and classified as intestinal (INT) and pancreaticobiliary (PB) types based on their morphological and immunohistochemical features, respectively. The morphologic subtypes, expression of IHC markers were correlated with different histologic parameters. Statistical Analysis: Chi-square test was used to study the association between different IHC markers with histologic parameters. Probability (P) values <0.05 were regarded as statistically significant. Results: The expression of CK7, CK20, CDX2 were studied in 50 cases to classify them as INT and pancreatobiliary subtypes. CK7 has high sensitivity (88.2%), CDX2 has high specificity (96.4%), CK20+/CDX2+ has both high sensitivity (94.2 percent) and specificity (89.2 percent) in differentiating INT from pancreatobiliary subtypes. The morphologic subtypes showed correlation with two variables (tumor grade, pathologic T stage). CK20 and CK20/CDX2 expression showed a positive correlation with tumor grade, pathologic T staging, and lymphovascular invasion. Conclusions: In conclusion, morphological classification can significantly discriminate histologic types, IHC plays a moderate role. However, the combined expression of CK20 and CDX2 is helpful in subtyping.

Evaluation of the histopathologic status of rectal adenocarcinoma and its regional lymph nodes after neoadjuvant therapy, and its relation to the duration of disease-free survival |
p. 49 |
Farnaz Karimi, Hedieh Moradi Tabriz, Hadi Ahmadi Amoli, Elham Nazar, Amir Abbas Vaezi DOI:10.4103/IJPM.IJPM_1331_20 PMID:35074965
Introduction: Colorectal cancer is one of the most common malignant tumors and has a relatively poor prognosis. Lymph node involvement is considered the most important prognostic factor. Materials and Methods: During a retrospective cohort study, 132 patients with locally advanced rectal cancer who underwent neoadjuvant chemoradiotherapy followed by surgery for resectable rectal cancer from 2010 to 2015 in Sina hospital were reviewed. Results: Multivariable analysis was performed and shown the clinical stage was not a representative factor for disease-free survival (P = 0.187), but Dworak Tumor Regression Grading were significantly associated with higher disease-free survival (P = 0.000) in stage II and stage III. The total number of retrieved lymph nodes and involved lymph nodes in the same clinical stage were statistically associated with higher mean disease-free survival in patients (P = 0.000 in both conditions). Conclusion: In the same clinical stage, increasing the Dworak Tumor Regression Grading reduced the risk of rectal cancer recurrence. Increasing total number of retrieved lymph nodes and involved lymph nodes, 2.14 times and 3.87 times increased the risk of recurrence, respectively.

p. 55 |
Aynur Atilla, Mehmet H Taşkın, Zülay Kazak, Saliha Aydın, S Sırrı Kılıç DOI:10.4103/IJPM.IJPM_1149_20 PMID:35074966
Background/Aims: In this study, we investigated the Golgi protein 73 (GP73) level in Hepatitis B and determined the correlation between Hepatitis B virus (HBV) DNA, alanine aminotransferase (ALT), aspartate aminotransferase (AST) levels, and liver histopathology. Materials and Methods: GP73 levels were estimated by enzyme-linked immunosorbent assay in serum samples from patients. Liver biopsy specimens were examined by the same pathologist. Results: This study included a total of 127 patients who underwent liver biopsy. Of patients, 85% were HBeAg negative. HBV DNA level was median 134667 IU/mL (2247–170000000 IU/mL), Liver biopsy results revealed a mean Histological Activity Index (HAI) grade of 7.7 ± 3.4 and a mean fibrosis stage of 2.25 ± 1.06 gr/dL. GP73 was as follows: a mean of 14.8 ± 7.9 ng/mL and a median of 12.9 (4.8–50.1) ng/mL. A weak correlation between GP73 level and AST (r = 0.236, P = 0.11), fibrosis stage (r = 0.287, P = 0.002), and HAI grade (r = 0.218, P = 0.016) was noted. No statistically significant correlation was detected between GP73 and ALT (r = 0.16, P = 0.08), HBV DNA (r = 0.13, P = 0.08). Conclusion: Although recent studies revealed a strong correlation and increased GP73 levels in accordance with HAI scores and the fibrosis grade of liver, we detected a weak correlation between serum GP73 levels and HAI scores, fibrosis stage, and AST. This may be due to the insufficient number of patients with higher HAI grading and fibrosis staging in our study. Therefore, we concluded that, in cases of low-moderate fibrosis and HAI grading, GP73 seemed not to be useful and a reliable marker to replace liver biopsy.

Spectrum of renal diseases in the elderly, above age 50 |
p. 59 |
Pratishtha Sengar, Pallav Gupta DOI:10.4103/IJPM.IJPM_1001_20 PMID:35074967
Background: The spectrum of kidney diseases varies in the elderly population with frequent inconsistencies between clinical presentation and histopathological diagnosis. The immunofluorescence (IF) may provide additional information in such situations. Aims: The purpose was to study the spectrum of kidney diseases in patients above 50 years undergoing renal biopsy and utility of light chain (LC) IF in the diagnosis. Settings and Design: This was a retrospective, crosssectional, singlecenter-based study. Material and Methods: The clinical details, histopathological findings, and LC IF pattern in native renal biopsy of patients above 50 years were noted. Statistical Analysis: Continuous variables were presented as mean ± standard deviation (SD). Categorical variables were expressed as frequencies and percentages. Results: A total of 205 patients were included in the study. The most common clinical presentation was acute kidney injury/rapidly progressive glomerulonephritis (AKI/RPGN) (49%). Glomerular diseases (72%) were more common. Crescentic glomerulonephritis (21%) and membranous nephropathy (MN) (19%) were the most common glomerulopathy. LC restriction was observed in LC cast nephropathy (LCCN), primary amyloidosis, and LC also helped in classifying the cases of MPGN-type morphology. Conclusions: AKI/RPGN was the most common indication for renal biopsy in patients above 50 years. Crescentic GN and MN were the frequent glomerular pathology. LC IF is a useful adjunctive tool to classify various renal diseases.

Detection of MDM2 gene amplification on tissue microarray-based Fluorescence In-Situ Hybridization (FISH) in well-differentiated and dedifferentiated liposarcomas, displaying a wide morphological spectrum: A validation study at a tertiary cancer referral centre |
p. 65 |
Bharat Rekhi, Nupur Karnik, Radhika Agrawal, Omshree Shetty, Shraddha Patkar DOI:10.4103/IJPM.IJPM_1238_20 PMID:35074968
Background: Liposarcomas including atypical lipomatous tumors (ALT)/well-differentiated liposarcomas (WDLPS) and dedifferentiated liposarcomas (DDLPSs) display a histomorphological spectrum with their several diagnostic mimics. Murine double minute 2(MDM2) gene amplification characterizes ALT/WDLPS and DDLPS. Presently, there is no documented study from our subcontinent on the validation of MDM2 gene testing in these tumors. Material and Methods: Twenty-eight cases, diagnosed as ALT/WDLPS (n = 5) and DDLPSs (n = 23), along with 10 other tumors were tested for MDM2 gene amplification, using fluorescence in situ hybridization (FISH) on tissue microarrays (TMAs). Fourteen cases, diagnosed as ALT/WDLPS and DDLPS, along with 49 other tumors were tested for MDM2 immunostaining. Twenty tumors were tested for p16INK4a immunostaining. Results: FISH was interpretable in 25 (89.2%) cases. Among the 20 cases diagnosed as DDLPSs, 19 displayed MDM2 gene amplification. Among the 5 cases diagnosed as ALT/WDLPS, four showed MDM2 gene amplification. Finally, 19 cases were confirmed as DDLPS and 4 as ALT/WDLPS. Furthermore, 7/19 cases confirmed as DDLPS and all 4 cases as ALT/WDLPS tested for MDM2 immunostaining, displayed its diffuse immunoexpression, while a single case of DDLPS showed its focal immunostaining. None of the 49 control cases displayed diffuse MDM2 immunoexpression. ALL 16 DDLPSs and 4 cases of ALT/WDLPS displayed p16INK4a immunostaining. The sensitivity for diffuse MDM2 immunostaining was 87.5% in cases of DDLPS, 100% in ALT/WDLPS, and specificity was 100%. The sensitivity for MDM2 gene amplification was 94.7% in cases of DDLPS and 100% in cases of ALT/WDLPS. The sensitivity for p16INK4a was 100%. Conclusion: This constitutes the first sizable study on MDM2 testing in ALT/WDLPS and DDLPS from our subcontinent using TMAs. MDM2 gene amplification testing continues as the diagnostic gold standard for ALTs/WDLPSs and DDLPSs and is useful in cases of diagnostic dilemmas. Diffuse MDM2 (IF2 clone) and p16INK4a immunostaining, together seem useful for triaging cases for FISH.

Disseminated epithelial cancers—An autopsy analysis |
p. 76 |
Pradeep Vaideeswar, Sachin Patil, Jayashri Chaudhari DOI:10.4103/IJPM.IJPM_1048_20 PMID:35074969
Background: Cancer is one of the leading causes of death due to noncommunicable diseases worldwide. Despite increasing public awareness and availability of sophisticated imaging techniques, some cancers evade clinical diagnosis and/or are incidentally encountered at autopsies, often with dissemination. Aims: The present study evaluated the disseminated epithelial cancers at autopsy. Materials and Methods: This is a retrospective observational 5-year autopsy analysis of disseminated epithelial cancers performed at a tertiary-care hospital. The cases were categorized as (1) clinically diagnosed malignancy, known primary; (2) clinically diagnosed malignancy, unknown primary; and (3) clinically undiagnosed malignancy. Statistical Analysis: Nil. Results: Dissemination was identified in 66 (57.9%) of the 114 patients with epithelial malignancies. There were 29 patients (43.9%) in category 1, 26 patients (39.4%) in category 2, and 11 patients (16.7%) in category 3, majority of whom were women (38 patients, 57.6%). When all categories were considered together, lung and colorectal carcinomas were the commonest cancers seen in 13 (19.7%) and 8 (12.1%) patients, respectively, in both men and women. Majority of the patients (43 cases, 65.2%) had symptoms produced by metastases, which were the sole manifestations in 13 patients (19.7%). Lungs and liver were the common metastatic sites. Conclusions: Cancerous dissemination continues to be a major cause of morbidity and mortality even after considerable improvements in the surgical or nonsurgical treatment modalities. An autopsy study can provide important clinical insights in retrospect.

Evaluation of microsatellite instability in routine examinations of surgical samples |
p. 87 |
Pawel Wlaszczuk, Aleksandra Kuzbinska, Zuzanna Dobrosz, Piotr Palen, Krzysztof Pawlicki DOI:10.4103/IJPM.IJPM_1398_20 PMID:35074970
Context: Approximately 20%–30% of colon cancer cases have a hereditary basis. The genetic defect may involve mismatch repair (MMR) genes, which results in microsatellite instability (MSI). MMR-deficient colorectal cancer may occur due to germline mutation (Lynch syndrome) or be a sporadic one. A tumor's histological features, supported by a panel of immunohistochemistry stains, enables pathologists to assess the MMR status, which in turn has beneficial effects on clinical management. Aims: We aimed to show the relations between histopathological features identified during routine examinations and MMR genes' mutations. Methods and Material: We reviewed retrospectively the material of the Department of Pathology fulfilling the revised Bethesda Guidelines. Statistical Analysis Used: We used Chi-square test, Spearman test, and epidemiological analysis. Results: For the PMS2 gene, the positive predictive value (PPV) indicates that 91% of cases neither present any histological lesions nor have genetic abnormalities. The negative predictive value (NPV) indicates that only 50% of cases have both histological and genetic changes. For the MSH6 gene, the PPV indicates that 85% of tumors without specific histological features do not have genetic abnormalities. Conclusions: We advise universal staining for MLH1, MSH2, MSH6, and PMS2 in every newly diagnosed colon cancer, but due to costly analyses we suggest a protocol for the selection of cases for MMR examinations.

Comparison of circulating DNA in malignant neoplasia from diverse locations: Investigating a diagnostic role |
p. 93 |
Swati Kumari, Sridhar Mishra, Nuzhat Husain, Tripti Verma, Vandana Tiwari, Mohamed Kaif, Akash Agarwal, Madhup Rastogi, Saumya Shukla, Abhinav Arun Sonkar DOI:10.4103/IJPM.IJPM_474_20 PMID:35074971
Context: Circulating free DNA (cfDNA) analysis has emerged as novel noninvasive diagnostic biomarker in several solid tumors. Raised levels have been reported in several malignancies and may correlate with clinicopathological and treatment response. The current study was designed to assess the diagnostics of cfDNA in different tumor types of malignancies correlating with tumor (T), nodes (N), and metastases (M) stage. Design: Serum samples were collected from treatment naïve cases with histologically diagnosed tumors including 23 brain tumors, 48 breasts, 50 gallbladder carcinoma (GBC), 13 lungs, 68 oral squamous cell carcinoma (OSCC), and 25 normal controls. CfDNA was quantified with real-time polymerase chain reaction (PCR), Invasive ductal carcinoma (IDC) using beta-globin gene amplification. Cut off values for diagnostics were calculated using receiver operating curve analysis. Results: Contrary to other cfDNA studies where it was postulated that cfDNA would not cross the blood–brain barrier and reach the systemic circulation, we found detectable cfDNA in glioma with median (Q1–Q3) of 349.22 ng/ml (19.87–1276.58). Median cfDNA concentration in breast, gallbladder, lung, oral and normal controls was 328.72 (128.38–624.44), 778.50 (589.88–1864.35), 348.73 (194.67–483.61), 386.27 (47.88–959.67), and 74.12 (49.66–120.00), respectively. Grades I and II glioma had significantly lower levels compared to Grades III and IV (P = 0.0001). Significant difference in median cfDNA values in IDC and GBC was observed with increasing tumor grades, stage, T stage, nodal stage and metastasis and with stage of OSCC cases. Conclusion: CfDNA levels showed good diagnostic discrimination in glioma, GBC, breast, lung carcinoma, and OSCC. Significant increase in titers was evident with increase in cancer stage from I to IV in breast, GBC and OSCC.

Merits and pitfalls of normal saline rehydrated air-dried cervical smears over conventional wet.fixed PAP smears: A comparative study |
p. 100 |
Shilpa A Kamble, Vijay D Dombale, Forum Shah DOI:10.4103/IJPM.IJPM_1214_20 PMID:35074972
Background: Cervical Papanicolaou (PAP) smear is the simplest, minimal invasive, and excellent screening method to reduce the female morbidity and mortality due to cervical carcinoma. Immediate alcohol fixation of the cervical smears is required to preserve nuclear details, delay in alcohol fixation leads to air drying artifacts. Rehydrating of the air-dried cervical pap smear with normal saline can help to overcome these artifacts and also have its own advantages. Aims: This study was design to evaluate the effects, merits and pitfalls of normal saline Rehydrated Air-Dried Cervical PAP Smears (RADPS) compared with the Conventional Papanicolaou Smear (C-PAPS). Settings and Design: Comparative study. Methods and Material: Prospectively paired cervical smears of 100 women, who presented to the outpatient department of gynecology of our institute, were prepared. Alcohol fixed smears were labelled as conventional Papanicolaou smear (C-PAPS) and air-dried smears labelled as rehydrated air-dried PAP smears (RADPS). Eight cytomorphological parameters were considered for comparison and analyzed. Statistical analysis used: Chisquare (χ2)/Fisher exact test. Results: Clear background with red blood cells (RBC) lysis was noted in 93% of RADPS and 54% of C-PAPS. Cytolysis was observed more in C-PAPS (18%) than in RADPS (08%). Air-drying artifacts observed in 30% of C-PAPS and 08% of RADPS. Cytoplasmic staining (92% of RADPS and 85% of C-PAPS) was superior in RADPS. Cell border, nuclear chromatin, and border were also better appreciated on RADPS as compared to C-PAPS. Statistically significant difference was observed with 3 parameters, i.e., air-drying artifacts, RBC background, and distinct cell borders. Conclusion: Rehydration of air-dried smears can be adopted in regular practice, as an alternative or coupled with conventional wet fixation method to overcome the commonly faced problems of air-drying artifacts, especially in rural screening programs.

Experience of quantity and quality of DNA and RNA extraction from limited pediatric blood samples: A comparative analysis of automated and manual kit-based method |
p. 105 |
Pankaj Sharma, Minu Singh, Aditya Singh, Deepshikha Bhardwaj, Prateek Bhatia DOI:10.4103/IJPM.IJPM_946_20 PMID:35074973
Introduction: Optimal DNA and RNA quantity and purity is essential for downstream molecular biology experimentation and to avoid re-processing of sample. Despite availability of different kits and automated systems for nucleic acid isolation there is limited data on their performance evaluation, more so with pediatric blood samples, that are usually compromised in quantity. Hence, we evaluated the performance of automated QIAcube platform using pediatric blood samples in parallel with manual Qiagen extraction kits. Materials and Methods: A total of 500 samples were analyzed based on groups of PBMC and direct blood input. The isolated DNA and RNA were surveyed for quantity and quality tests by spectrophotometric and downstream analysis. Results: There was no significant difference in the DNA quantity (ng/ul) between manual and automated method based on similar sample input but quality (260/280) was significantly better with the QIAcube platform when direct blood and or PBMCs were used for extraction respectively (1.82 ± 004 Vs. 1.84.002; P-0.000008 and 1.859 ± 005 Vs. 1.843 ± 0.003; P-0.02). Moreover, the standard error mean was low for both quantity and quality in the QIAcube method suggesting uniformity. Comparison of quality assessment by spectrophotometer and qubit fluorimeter showed that QIAcube sheared DNA less (P- 0.038) as compared to manual method (P-0.013). Also, time taken to process the samples in QIAcube was 23% less than the kit-based method. Conclusion: Overall analysis of QIAcube platform suggests that it yields more better, uniform, and less-sheared quality of nucleic acid in a relatively less time as compared to manual extraction kits.

Diagnostic value of different interleukins and procalcitonin in critically ill patients admitted with suspected sepsis |
p. 111 |
Simmi Mehra, Aseem Kumar Tiwari, Geet Aggarwal, Swati Pabbi Mehta, Rajni Chauhan, Chhavi Rajvanshi, Deepak Govil DOI:10.4103/IJPM.IJPM_647_20 PMID:35074974
Background: Many biomarkers have now been studied such as C-reactive Protein (CRP), procalcitonin (PCT), etc., and are widely used for the diagnosis of sepsis in clinical practice which may determine the appropriate antibiotic treatment. A flowcytometric cytokine bead array (CBA) assay has now been used to determine multiple interleukins (IL), simultaneously. The aim of this study was to determine the cytokine (IL2, IL4, IL6, IL10, TNFα, INFγ, and IL17) profiles of interleukins in plasma of sepsis patients by using multiplex Flowcytometric CBA array assay. Materials and Methods: A total of 99 consecutive patients admitted with the suspected sepsis were studied. PCT concentrations were measured by using the enzyme-linked fluorescent immunoassay (ELFA) technique and flow cytometry-based BD™ CBA Cytokine Kit was used to evaluate levels of 7 cytokines [IL-2, IL-4, IL-6, IL-10, Tumour Necrosis Factor (TNF), Interferon- γ (IFN-γ), and IL-17A]. Results: Microbiologically defined infection (MDI) demonstrated a positive culture report in 79/99 (79.7%) of patients. The IL6 [1873.7 (4-5000)] and IL10 [(154.7 (0-1764)] levels were significantly higher in septic patients than those in the negative MDI IL6 [901 (4-5000)] and IL10 [110.4 (4-1372)] levels. The AUROC value of IL6 [0.66 (0.53-0.79)] was found to be the highest among all followed by IL10 [0.65 (0.51-0.79)], IFNγ [0.63 (0.51-0.77)], PCT [0.61 (0.48-0.75)], and TNFα [0.55 (0.42-0.69)]. Conclusion: Our study suggests that that IL6 is substantially more economical and can reduce the investigation cost to half as compared with the procalcitonin assay.

Survey of semen analysis practices in India and need for standardization and improvement |
p. 117 |
Sachin Kale, Sandeep Bathe, Ranjan Agrawal, Purva More, Era Bharadwaj DOI:10.4103/ijpm.ijpm_475_21 PMID:35074975
Background and Objectives: Infertility is a sensitive subject carrying with it economic, social, and psychological implications. Work up of male infertility is often hampered by a lack of infrastructure and facilities, as well as inadequate training of pathology residents. The purpose of this research survey was to evaluate the current status of semen analysis practices and compare them to the standards laid down by the World Health Organization (WHO). Materials and Methods: A web-based questionnaire was designed consisting of questions related to semen analysis practices and procedures being followed currently by pathologists in India. A total of 194 pathologists responded. Questions regarding the procedures followed for semen collection, sperm count, volume, normal range, lower normal limit of sperm count, morphology, etc., were included in the survey. These data were recorded. The differences and gaps in the practice with respect to the WHO standards were analyzed. Results: The survey revealed that the printed instructions for semen analysis were available with 38.7% of the respondents; 58.8% of the respondents had a separate room for semen collection; 95.9% performed the analysis manually, and; only 4.1% used automated analyzers. Only 53.6 and 52.6% of the respondents were correctly reporting the normal range of semen volume and sperm counts, respectively. Only 19.6% stated as having read the WHO manual and were also practicing its guidelines, while 14.4% had not read the WHO manual even once. Conclusion: The present study showed a large gap between the practice of semen analysis by respondents from various parts of India and standard procedures as laid down by the WHO. Many laboratories do not follow the standard instructions. There is a need to improve the quality of practice related to semen analysis in this country through appropriate teaching and training in medical institutions as well as through Continuing Medical Education (CMEs) or regular update programs.

Salivary microbial dysbiosis may predict lung adenocarcinoma: A pilot study |
p. 123 |
Partha Roy, Anupam Sarma, Amal Ch Kataki, Avdhesh Kumar Rai, Indranil Chattopadhyay DOI:10.4103/IJPM.IJPM_1111_20 PMID:35074976
Background: Adenocarcinoma is a more common type of Non-small cell lung cancer (NSCLC). Lung cancer showed a statistically significant increment in the Kamrup Urban district of Assam, Tripura, Sikkim, and Manipur of India. The goal of our pilot study is to identify non-invasive microbial biomarkers to detect lung adenocarcinoma (LAC). Material and Methods: DNA extraction from saliva samples of five LAC patients and five healthy controls was performed by Qiagen DNeasy blood and tissue kit using Lysozyme (3mg/ml) treatment. 16S rRNA genes of distinct regions (V3-V4) were amplified from saliva DNA by PCR. Paired-end sequencing targeting the V3-V4 region of the 16S rRNA gene has been performed on the Illumina MiSeq platform. Raw sequences were analyzed using the QIIME(Quantitative Insights Into Microbial Ecology) software package. Results: Our preliminary results showed that Rothia mucilaginosa, Veillonella dispar, Prevotella melaninogenica, Prevotella pallens, Prevotella copri, Haemophilus parainfluenzae, Neisseria bacilliformis and Aggregatibacter segnis were significantly elevated in saliva of LAC which may serve as potential non-invasive biomarkers for LAC detection. Functional prediction analysis showed that bacterial genes involved in glycosyltransferase, peptidases, amino sugar, and nucleotide sugar metabolism, starch and sucrose metabolism were significantly enriched in LAC. Conclusion: These salivary bacteria may contribute to the development of LAC by increasing expression of glycosyltransferase and peptidases. However to understand their role in pathobiology, studies are required to perform in large cohort.

Shweta Bansod, Pradeep Vaideeswar, Sangeeta Ravat, Gajanan Panandikar DOI:10.4103/IJPM.IJPM_935_20 PMID:35074977
Background: Myasthenia gravis (MG) is a prototypic T-cell-dependent antibody-mediated autoimmune disease that leads to ocular or generalized muscular weakness. The disease is most commonly caused by antibodies to the acetylcholine receptors, often with underlying thymic pathology. Aims: This study is aimed at analyzing the pathological spectrum of the excised thymuses in patients with myasthenia. Materials and Methods: This was a retrospective 10-year study of 68 thymectomy specimens performed as a part of the treatment of patients with MG. Statistical Analysis: Nil. Results: There were 47 males and 21 females (male to female ratio of 2.2:1) with a mean age of 41 years. Only three patients presented with ocular myasthenia. The thymus was normal in 9 patients (13.2%) and atrophic in 17 patients (25%). Follicular hyperplasia and thymomas were seen in 6 and 36 patients, respectively. Conclusion: The thymectomies performed in patients of MG had a fairly variable spectrum on histology; the thymic tumors were predominantly of the cortical phenotype.

Apurva Dale Mundada, Kedar Deodhar, Mukta Ramadwar, Munita Bal, Rajiv Kumar DOI:10.4103/ijpm.ijpm_350_21 PMID:35074978
Primary hepatic epithelioid hemangioendothelioma (HEHE) is a rare tumor with an incidence of <0.1 per 100,000. The clinical course is variable with variable outcomes. Due to its rarity, treatment protocols, prognostic and predictive factors are not well established underscoring the need for such a study. Pathologists' awareness of this entity, a meticulous morphologic examination coupled with immunohistochemistry can aid in accurate diagnosis.

Primary follicular lymphoma of the gut (PFL-GI) is a rare entity. This study aims to compare the clinicopathologic features of PFL-GI with cases of gastrointestinal involvement by disseminated nodal follicular lymphoma. This is a retrospective study with 6 cases of primary follicular lymphoma and 8 cases of secondary involvement of the gut, over a period of 9 years. The slides and blocks were retrieved and reviewed. Clinical data was obtained from hospital records. Clinicopathologic features were compared. PFL-GI cases had a slightly higher median age group (p value 0.23) and no gender predilection when compared to cases with secondary involvement which showed a female preponderance. Para-aortic lymphadenopathy was seen in all secondary cases whereas none of the primary cases showed significant lymphadenopathy. The only microscopic feature that was different was the presence of hollowed out pattern of immunostaining for follicular dendritic cells seen in all cases of PFL-GI but in none of the secondary cases

Primary leiomyosarcoma of the thyroid gland |
p. 142 |
Manveen Kaur, Debajyoti Chatterjee, Phiza Aggarwal, Vaibhav Saini DOI:10.4103/IJPM.IJPM_1380_20 PMID:35074980
Sarcoma is a rare tumor of the thyroid gland, primary thyroid leiomyosarcoma (LMS) being even rarer. We present a case of LMS of the thyroid in a middle-aged female. Histopathologic examination in conjunction with immunohistochemistry helped to clinch the diagnosis. Knowledge of this entity is important to distinguish it from anaplastic thyroid carcinoma (ATC) and other sarcomas arising in the thyroid and adjacent soft tissue. The prognosis of thyroid LMS is dismal with an extremely poor survival rate.

Pulmonary carcinosarcoma with an aggressive heterologous angiosarcoma component: A case report |
p. 145 |
Jonathan Y Keow, Richard I Inculet, Robert Hammond, Cady Zeman-Pocrnich DOI:10.4103/IJPM.IJPM_1451_20 PMID:35074981
Pulmonary carcinosarcomas are rare biphasic lung tumors comprised of malignant epithelial and malignant mesenchymal components. The most common heterologous sarcomatous elements are osteosarcoma, rhabdomyosarcoma, and chondrosarcoma; a heterologous angiosarcoma component in a pulmonary carcinosarcoma is exceedingly rare. We report a case of a pulmonary carcinosarcoma containing adenocarcinoma, squamous cell carcinoma, undifferentiated malignant spindle cell, and heterologous angiosarcoma components. The patient, a 64-year-old woman, had initially presented to medical attention with hemoptysis. Although the tumor was thought to be confined to the lung at resection (pT3N0), she developed multiple metastatic foci within 3 weeks of lobectomy and required the evacuation of an intraparenchymal left occipital hematoma secondary to a hemorrhagic intra-axial focus of metastatic carcinosarcoma. She died 6 weeks after her primary lung resection from rapidly progressive metastatic disease. We hope the description and discussion provided herein will further the medical community's understanding of this rare malignancy.

Cystic hypersecretory carcinoma with invasion: Case series on a rare variant of carcinoma breast |
p. 149 |
Hibu Yami, Renu Thambi, PV Priya, Sankar Sundaram DOI:10.4103/IJPM.IJPM_911_20 PMID:35074982
Background: Cystic Hypersecretory Carcinoma (CHC) is a rare subset of breast carcinoma. It is part of a spectrum of cystic hypersecretory lesions which includes cystic hypersecretory hyperplasia (CHH), CHH with atypia, CHC in situ and CHC with invasion. Approximately 65 cases of cystic hypersecretory lesions have been reported; most of them were CHC in situ and only 19 cases of CHC with invasion have been reported so far. Case Presentation: We are reporting 2 cases of 47 and 62 year old women with a palpable breast mass for 6 and 1 month duration respectively. Trucut biopsy was carried out for both which showed high grade ductal carcinoma in situ with microinvasion in the first patient and the latter showed a tiny focus of invasive carcinoma. Simple mastectomy and modified radical mastectomy (MRM) were done for the respective cases; both showed dilated cystic spaces filled with eosinophilic secretions (thyroid colloid-like), lining neoplastic cells that showed variable degrees of proliferation, atypia and in situ carcinoma. There were foci of invasion in both cases and hence a morphological diagnosis of CHC with invasion was made. Conclusion: Owing to a smaller number of reported cases, little is known about the biological behavior, prognosis and molecular profile of cystic hypersecretory carcinoma.

Background: Primary Breast Sarcomas (PBS) are rare malignancies and seen in less than <1 % of all breast malignancies. PBS are non epithelial, composed of mesenchymal mammary tissue and are difficult to diagnose from other sarcomas arising in breast. Materials and Methods: A retrospective study was conducted in the Department of Pathology and slides of breast malignancies over a period of 5 years were reviewed. Out of total 1570 breast malignancies, 5 cases were reported as PBS. Diagnosis was made on the basis of Histopathology and IHC findings. Results: Out of total 1570 cases, 5 cases were diagnosed as PBS (i.e. 0.32% of all cases). 3 out of 5 cases were males comprising of 60% of cases and 2 cases were females accounting for 40% of cases. The age group of presentation was 32-65 years with mean age being 48.5 years. A diagnosis of MPNST was rendered in two cases ( 1=M, 1=F), one each was diagnosed as DFSP ( with fibrosarcoma), Leiomyosarcoma and Fibrosarcoma. Conclusion: PBS is an extremely rare entity and locally aggressive. It requires diagnosis as its treatment protocol is different.

Myocardial bridging – Sudden unexpected death of a young girl: A case report |
p. 157 |
Durre Aden, Ravi Hari Phulware, Sachin Mittal, Arvind Ahuja DOI:10.4103/IJPM.IJPM_1177_20 PMID:35074984
Myocardial bridging (MB) is a relatively uncommon congenital anomaly where a segment of the coronary artery dips inside the myocardium and takes a tunneled course under a bridge of the myocardium. This leads to the compression of the coronary artery during systole resulting in hemodynamic changes and their clinical manifestations. However, it is an incidental finding but can present with multiple complications like myocardial ischemia, infarction, and sudden death, primarily when associated with other risk factors like left ventricular hypertrophy of the heart. Therefore, a careful examination of the heart is essential for evaluating the clinical significance of the MB. Here, we presented a case of a 30-year-old young female who had a sudden death, and her histological examination of the heart showed MB of left anterior descending coronary artery (LAD).

Chadha Kirti, Lila Kunjal, Gala Roshani DOI:10.4103/IJPM.IJPM_1364_20 PMID:35074985
Mediastinal masses span a wide histopathological spectrum. Inflammatory pseudotumors are rare and most commonly described in the lungs but these are reported in almost all the organs in the body. Mediastinal involvement is rare and difficult to diagnose. Clinical manifestations and laboratory investigations and radiology are non-specific. Histomorphology and Immunohistochemistry provide a valuable aid. Complete resection usually provides definitive diagnosis and is treatment of choice.

Glomus tumor of the crissum: A case report and review of literature |
p. 164 |
Yuanyin Zheng, Xiaobin Liu, Yingyu Mao, Maohua Lin DOI:10.4103/IJPM.IJPM_1237_20 PMID:35074986
Glomus tumor is a rare mesenchymal neoplasm arising from the modified smooth muscle cells of the glomus body. Primary crissum glomus tumor is extremely rare without any published in the literature. In this article, we report the first case of primary crissum glomus tumor in an 80-year-old man with recurrent anal pain for 8 years, increased pain for 1 year. Rectal MRI for inflammatory lesions (sinus tract). Microscopic examination showed the tumor cells were arranged in sheets and nests, surrounding blood vessels and nerve bundles. At high magnification, the neoplastic cells show regular round shape with light eosinophilic and translucent cytoplasm. The cell boundary is clear, the nucleus is round and located in the center. The stroma of the tumor shows hyaline degeneration. Immunohistochemically, the tumor cells were positive for smooth muscle actin, h-caldesmon, Calponin, synaptophysin, Collagen IV and CD34, but completely negative for HMB45, S100, EMA, desmin, CgA and CD56. The histologic features and immunohistochemical profile supported a diagnosis of primary crissum glomus tumor. The patient was asymptomatic and disease free after the procedure.

Kaposiform hemangioendothelioma in an unusual site: A report of two cases in children |
p. 167 |
Sumanta Bhattacharya, Paromita Roy, Uttara Chatterjee, Arpita Bhattacharyya DOI:10.4103/IJPM.IJPM_489_20 PMID:35074987
Kaposiform hemangioendothelioma (KHE) is a locally aggressive vascular tumor usually seen in children. It is frequently associated with Kasabach-Merritt phenomenon. Here we report two cases of KHE: the first case being an 11-month-old boy who came with massive swelling on the face and violaceous discoloration. The second case was a 7-year-old boy who presented with respiratory distress and bleeding manifestations. CT scan chest showed a large mass involving the anterior mediastinum. Histologic examination of resected masses from both these cases showed features of KHE involving subcutaneous tissue and thymus, respectively. Although cutaneous and subcutaneous location is common, thymic involvement is unusual. It is important to distinguish KHE from infantile haemangioma, tufted angioma, spindle-cell haemangioma, verrucous malformation and Kaposi sarcoma. Histologic features, supportive immunohistochemistry and the clinical profile together are helpful to differentiate KHE from other vascular lesions.

Renal tuberculosis presenting as renal cyst is rare. Diagnosing renal tuberculosis in pregnancy is usually delayed due to its atypical presentation. We present a 28-year-old postpartum lady who delivered a healthy baby one month back, with history of intermittent fever and chills. She had high spiking fever (102° F), tachycardia (130/min) and computed tomography showed a 16 × 10 cm right renal cyst. Percutaneous drainage was done, 2 litres of thick pus drained and culture was sterile. After three weeks, deroofing and marsupialization of cyst was done. Biopsy revealed granulomatous inflammation composed of epitheliod histiocytes with central incipient necrosis suggestive of tuberculosis. She was treated with anti-tubercular drugs. As the infant was healthy and had no evidence of tuberculosis, no treatment was initiated. The mother is on follow up for 2 years. This case highlights the rare presentation of renal tuberculosis in puerperium.

Lésion d'Antopol-Goldman (Antopol-Goldman lesion): Spontaneous renal pelvic subepithelial hematoma |
p. 173 |
Sharma Swati, Chawla Arun, Choudhary Anupam, Chethana Babu K Udupa, Pai Kanthilata, M Godkhindi Vishwapriya DOI:10.4103/ijpm.ijpm_111_21 PMID:35074989
Lésion d'Antopol-Goldman (Antopol-Goldman lesion) is a rare condition characterized by renal pelvic subepithelial hematoma simulating a neoplastic process. A 71-year-old lady presented with macroscopic hematuria and hypoenhancing mass lesion at the upper pole of left kidney. The patient underwent a radical nephrectomy for suspected renal cell carcinoma. Macroscopically a 3.5cm circumscribed hemorrhagic mass lesion was noted flush with the upper pole pelvicalyceal system. Microscopic examination revealed a pelvic subepithelial (suburothelial) organizing hematoma. Extensive sampling did not reveal any neoplastic etiology. The adjacent renal parenchyma and renal vessels were unremarkable. Antopol-Goldman lesion is a diagnostic quagmire, often culminating in unnecessary nephrectomy. This is a rare entity, and clinical awareness as a differential of renal filling defect can preclude a nephrectomy, we hereby discuss its clinico-pathological and treatment implications.

Inflammatory myofibroblastic tumor of the kidney in patient with nephron-sparing surgery. Case report and review of the literature |
p. 176 |
Agnieszka Korolczuk, Piotr Jarosz, Patryk Jasielski, Przemysław Mitura1, Krzysztof Bar DOI:10.4103/ijpm.ijpm_11_21 PMID:35074990
According to the WHO classification, mesenchymal tumors of the kidney are divided into mesenchymal tumors occurring mainly in adults and children. Accumulating evidence suggests that renal mesenchymal tumors represent a group of histologically heterogeneous diseases. We are reporting the case of a 58-year-old man with a history of nephron-sparing surgery due to renal cell carcinoma in 2014 in his left kidney. He was urgently admitted to the hospital due to left-sided nephrotoxic and anuria. Computed tomography (CT) imaging was performed and revealed irregular tumor mass. He underwent left-sided nephrectomy. Microscopic appearance and immunoprofile allowed to diagnose the tumor as an inflammatory myofibroblastic tumor (IMT) of the kidney. According to the 2016 World Health Organization (WHO) classification of tumors of the urinary system and male genital organs, IMT is a benign mesenchymal tumor with malignant potential. Typical locations are the liver and biliary tract, lung, and gastrointestinal tract. In the urogenital system, IMT occurs mainly in the bladder. So far, 48 cases have been reported in the kidney.

Phosphaturic mesenchymal tumor: An underdiagnosed rare entity |
p. 181 |
Sanjiban Patra, Priti Trivedi, Chirag Jhaveri DOI:10.4103/IJPM.IJPM_1341_20 PMID:35074991
Tumor-induced osteomalacia is a paraneoplastic syndrome resulting in renal phosphate wasting and decreased bone mineralization. Phosphaturic mesenchymal tumors represent a rare etiology of tumor-induced osteomalacia. They are exceptionally rare, probably accounting for < 0.01% of all soft tissue tumors. Most PMTs present as small inapparent lesions that require very careful clinical examination and radionucleotide scan for localization. Here we describe a case in a 65 years old woman with recurrent multiple bone fractures and subsequent detection of a tumor involving right femur and adjacent soft tissue, low phosphate level and elevated serum Fibroblast growth factor-23 (FGF-23).

Primary ovarian mucinous carcinoid arising in a mature cystic teratoma-A rare entity |
p. 184 |
Blessy M Thomas, Elizabeth Joseph, Renji Mathew, John S Kurien DOI:10.4103/IJPM.IJPM_1357_20 PMID:35074992
Mature cystic teratomas are benign unilateral tumors often diagnosed in young females. Carcinoid tumors are slow-growing tumors originating from neuroendocrine cells. A thorough histopathological study of the tumor is mandatory and the surgical treatment is adapted according to the characteristics of the patient. The present case was considered as a primary mucinous carcinoid tumor of the ovary because it was confined to the ovary, had an intact capsule, no vascular invasion, or other suspicious lesions were noted in the abdominal cavity. This case is notable due to the rarity of its occurrence and the age of presentation.

Melanosis tubae et ovarii: An overlooked entity? |
p. 187 |
Ashutosh Rath, Bhagyashree Priyadarshini, Varuna Mallya, Nita Khurana, Anjali Tempe DOI:10.4103/IJPM.IJPM_424_20 PMID:35074993
Melanosis is a rare benign entity defined by the deposition of brownish-black pigment in a wide variety of organs especially the gastrointestinal tract, peritoneum, fallopian tubes and ovaries. Melanosis of the fallopian tube is widely known as pigmentosis tubae. Literature has mentioned ovarian teratomas and serous cystadenomas to be associated with the ovarian and peritoneal melanosis. We report five such cases of tubo-ovarian melanosis. The cases include mature teratoma and serous cystadenoma as well as melanosis of the fallopian tubes with otherwise normal ovarian histology. The importance of recognising this entity lies in its differential diagnosis.

Erythrophagocytosis in a patient with B-cell acute lymphoblastic leukemia with t(12;21) (p13.2; q22.1); ETV6-RUNX1: Case report and review of the literature |
p. 191 |
Sunita Sharma, Kavita Gaur, Srijan Srivastav, Piali Mandal DOI:10.4103/IJPM.IJPM_1154_20 PMID:35074994
Erythrophagocytosis (EP) is extremely rare in de novo acute lymphoblastic leukemia (ALL). We document a rare case, which in addition, showed extensive blast vacuolization. A detailed literature review has also been incorporated with the aim of unraveling the prognostic import of our morphological observations if any. A five-year-old male presented with fever and progressive pallor for 1 month. He had hepatosplenomegaly and bicytopenia. Peripheral smear examination showed 43% blasts. Nuclear and cytoplasmic vacuolations were seen in 75% blasts and EP in 4% blasts. The blasts showed block positivity on periodic acid-Schiff (PAS) stain. Marrow aspirate smears showed 58% blasts displaying a similar morphology. Flow cytometry showed features of a common acute lymphoblastic leukemia antigen (CALLA) positive B-cell ALL with aberrant, dim CD 33 expression in 53.4% of the gated blasts. Fluorescence in situ hybridization showed translocation (12; 21) (p13;q22). The patient responded well to standard induction therapy. To conclude, EP is rarely seen in de novo ALL and is associated with a favorable translocation, t(12;21).

Cold autoimmune hemolytic anemia with myelodysplastic syndrome: Not just an “Open and Shut case” |
p. 195 |
Deepti Mutreja, Gourang Paliwal, Vishal Mangal, Amit K Biswas DOI:10.4103/IJPM.IJPM_981_20 PMID:35074995
Myelodysplastic syndromes (MDSs) are clonal hematopoietic stem cell neoplasms characterized by bone marrow failure leading to ineffective hematopoiesis, dyspoiesis, and cytopenias with a risk of progression to acute leukemia. Immunological syndromes have been reported to occur along with MDS in literature. However, cold autoimmune hemolytic anemia (AIHA) has rarely been reported in association with MDS. Herein, we report a case of an elderly male who presented with fever and cytopenias. He was being treated as a case of megaloblastic anemia in the past with no response to therapy. At present admission, the peripheral blood smear examination revealed red cell agglutination, thrombocytopenia with 4% blasts. Cold agglutinin disease was confirmed by a thermal agglutination test and bone marrow evaluation showed adequate megakaryocytes with 10% blasts; consistent with the diagnosis of MDS with excess blasts (MDS-EB2). Cytogenetic studies revealed multiple abnormalities. This report is being discussed in view of its rarity of presentation of cold AIHA with MDS.

Omental desmoplastic small round cell tumor with metastasis |
p. 208 |
Raghav Yelamanchi, Ekta Yadav, Nikhil Gupta, Arvind Ahuja, DS Chauhan DOI:10.4103/IJPM.IJPM_548_20 PMID:35075000
Desmoplastic small round cell tumor (DSRCT) is a very rare diagnosis with about 200 cases reported in literature. DSRCT is a recently described histopathological entity by Gerald and Rosai in 1989. Abdominopelvic cavity especially peritoneum is the most common site. We report a case of a huge omental DSRCT with lymph node metastasis which was initially misdiagnosed as gastrointestinal stromal tumor on radiology. A 26-year-old male presented with complaints of upper abdominal swelling associated with constant dull pain. On examination there was a large 15 × 12 cm intraabdominal mass in the epigastric and umbilical region. Imaging studies were suggestive of neoplastic mesenchymal etiology. Image-guided fine-needle aspiration cytology (FNAC) was suggestive of mesenchymal neoplastic etiology. On laparotomy, there was a huge 20 × 15 cm mass arising from omentum with multiple omental and mesenteric seedlings and mesenteric, peripancreatic and perigastric lymphadenopathy. The patient underwent debulking surgery with uneventful post-operative recovery. Histopathological examination with immunohistochemistry revealed a diagnosis of DSRCT of omentum and small bowel mesentery with lymph node metastasis. Patient then received adjuvant chemotherapy with multiple chemotherapeutic drugs as per P6 protocol and has stable disease at 1 year follow up.
