Ewing's Sarcoma/Primitive Neuroectodermal Tumor of the Uterine Corpus

초록

Ewing's sarcoma (ES)/primitive neuroectodermal tumor (PN-ET) is defined as a round cell sarcoma that shows varying degrees of neuroectodermal differentiation. The term PNET was first introduced by Hart and Earle in 1973.(1) Cases of ES/PNET in the female genital tract are rare. Now we report a case of ES/PNET arising in the uterine body which was confirmed by all studies performed, including morphologic, immunohistochemical, ultrastructural, and cytogenetic examinations.
