(H & E x 100); sections show sheets and nests of pleomorphic cells having mainly hyperchromatic nuclei with mild to moderate eosinophilic cytoplasm, also seen is a focal area of necrosis (arrow)

Seen also were atypical mitotic figures and focal areas of necrosis with infiltration by acute and chronic inflammatory cells (Figure 1).

(H & E x 100); sections show sheets and vague nests of tumor cells having hyperchromatic to vesicular nuclei, indistinct nucleoli, and scant cytoplasm on a minimal fibrillary neural matrix, there are attempts at rosette formation in areas (Long arrow), also seen are atypical mitoses (short arrow)

There are attempts at rosette formation in areas (Figure 2) while on immunohistochemistry, the neoplastic cells showed strongly positive for both Neuron-Specific Enolase (NSE) and epithelial membrane antigen (EMA).
