Abstract：Primitive neuroectodermal tumor is a rare and highly malignant small round cell tumor. It can be divided into central PNET (cPNET) and peripheral PNET (pPNET). In addition to the lesions’ location, however,they are different in predilection age, route of metastasis, immunohistochemical staining, and chromosome translocation. So it is very necessary to identify each other, especially, when the lesions are close to the meninges or located in the vertebral canal. The aim of this review was to investigate the tumor genetics, clinical manifestation, pathologic diagnosis, imaging findings, treatment, and prognosis of the two kinds of tumors, also investigate the relationships between cPNET and pPNET, cPENT and medulloblastoma, pPNET and Ewing’s sarcoma.
