TY - JOUR T1 - PERIPHERAL NEUROEPITHELIOMA: A STUDY OF EIGHT CASES TT - JF - MJIRI JO - MJIRI VL - 8 IS - 1 UR - http://mjiri.iums.ac.ir/article-1-1396-en.html Y1 - 1994 SP - 5 EP - 8 N2 - Peripheral neuroepitbelioma (PN) is a rare highly malignant tumor, classified in the group of small round cell tumors. We report eight cases of PN, based on histologic appearance and immunohistochemical staining for neuron-specific enolase (NSE). Electron microscopy was also performed in three cases. The tumors exhibited rapid local growth, leading to limb amputation in five cases. Histologically the presence of Homer-Wright rosettes is a characteristic of this neoplasm. Tumoral cells are generally positive for NSE. The relationship ofPN with Ewing's sarcoma is discussed. M3 ER -
