Figure 1: (a) Tumor composed of polygonal-shaped cells, arranged in cords and in small clusters. with cytoplasmic clearing, at places. [H and E, × 200] (b). Cells containing moderate amount of eosinophilic to focally vacuolated cytoplasm and round to oval nuclei [H and E, × 400]. (c). Interspersed areas of eosinophilic material. Individual tumor cells displayed moderate degree of nuclear atypia. [H and E, × 400]. (d). By immunohistochemistry, tumor cells showing diffuse positivity for pan cytokeratin (AE1/AE3). [Diaminobenzidine, × 400]
