    Abstract:
    The term primitive neuroectodermal tumor (PNET) names a group of malignant neoplasms of presumed neural crest origin; they are composed of round small cells, and may be centrally located or outside. The former are currently seen in childhood, mostly in reference to the posterior fossa, and include medulloblastoma and neuroblastoma. Outside of the central nervous system includes peripheral neuroectodermal tumor of the bone (PNET-B, Tefft's tumor), Askin's tumor, and even Ewing's sarcoma. We describe a case in a young adult, with extremely unusual spinal localization, in which histopathological and immunohistochemical analysis were done; also, a review of some features is presented clinical-histopathological issues concerning related.
