case_images: Histological examination of biopsy material. A: Highly cellular neoplasm that are composed of cells with small- to medium-sized, hyperchromatic nuclei and little apparent cytoplasm (X40). B: Low power view. C: Vague Homer-Wright rosettes. D: Positive immunohistochemistry reaction for neuron specific enolase (NSE). E: Weak positive reaction for Synaptophysin. F: Positive Glial fibrillary acidic protein (GFAP) reaction. G: Negative epithelial membrane antigen (EMA) differentiate it from meningioma which is EMA positive). H: Negative CD99
