title: [Supratentorial primitive neuroectodermal tumor. Study of 4 cases].
abstract: The clinicopathological and immunohistochemical features of four cases of primitive neuroectodermal tumors of the central nervous system were investigated. Three patients died. All cases showed vimentin-positive cells with the morphology of neoplastic cells and one case showed glial fibrillary acidic protein, neuron-specific enolase and neurofilament protein-positive cell. The present study indicates that this group of tumors have bad prognostics and may show immunocytochemical features indicating glial and/or neuronal differentiation.
