Histopatologic features of the spinal GBM of the conus medullaris. Microscopy demonstrates a neoplastic proliferation of polymorphous glial cells characterized by anisocaryosis and atypical mitosis. a Focal necrosis, calcifications, and areas with multinucleated cells are present (×40). b Immunohistochemistry shows positivity for glial fibrillary acidic protein (GFAP) and S100 and negativity for sinaptofisine, neurofilaments, and the epithelial membrane antigen (EMA) (×63). c The proliferation index (anti-Ki67) is 15% (×63)
