case_images: (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)

case_images: 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).
