Figure 2: Neuroblastoma, differentiating; (a) Gross: a multinodular, solid-cystic mass received in pieces, cut surface (white arrow) of the solid area shows pale yellow gelatinous appearance; (b) Fibrous septa separates the neuroblastic nodules (H and E, 10×); (c, d) Neuroblasts and differentiating neuroblasts on the neuropil-rich background (H and E, 40×); (e) Differentiating neuroblasts with ganglion cells (H and E, 40×); (f) Strong expression of synaptophysin by neuroblastic cells (IHC, 40X); CT—Computed tomography; H and E—Hematoxylin and eosin; IHC—Immunohistochemistry
