Figure 2: (a) Histopathological section shows an infiltrating tumor arranged in sheets and nests separated by thick fibrocollagenous septa. (H and E stain, ×40). (b and c) Higher power shows tumor composed of small round blue cell having scant cytoplasm and round uniform nucleus. Brisk mitosis is noted in 2c. (H and E stain, ×100, ×400). (d) Periodic acid-Schiff stain shows coarse magenta granules in the cytoplasm. (Periodic acid-Schiff stain, ×400). (e) Immunohistochemistry with CD99 shows strong membrane positivity. (CD99 immunohistochemistry stain, ×400). (f) immunohistochemistry with synaptophysin (syn) shows focal cytoplasmic granular positivity. (Syn immunohistochemistry stain, ×400
