title: A primary primitive neuroectodermal tumor of the central nervous system in a 51-year-old woman: a case report and literature review.
abstract: Primitive neuroectodermal tumors are a group of rare, aggressive, and highly malignant embryonal tumors of unknown etiology of the central and peripheral nervous systems. It is a term for a group of small round cell tumors thought to be derived from fetal neuroectodermal precursor cells. Primitive neuroectodermal tumor is usually described as a tumor of children younger than 15 years and is very rare in adults. The article presents a short literature review and a rare case of a primary primitive neuroectodermal tumor of the central nervous system diagnosed in a 51-year-old woman.
