Primary Ewing’s sarcoma/primitive neuroectodermal tumor of the vagina in a 54-year-old woman: a case report

Abstract

Ewing's sarcoma (ES)/primitive neuroectodermal tumor (PNET) of the genital tract of women is uncommon. Presentation in vagina is exceedingly rare. A 54-year-old Chinese woman presented with complaints of vaginal bleeding with fragmented bits occasionally. Physical examination revealed two nodules about 4 cm × 3 cm in the vagina. The immunohistochemical stains revealed a rare presentation of a primitive neuroectodermal tumor. The patient was treated with whole-pelvis external beam radiation, vaginal cylinder intracavitary brachytherapy, intracavitary afterloading radiotherapy and bilateral groin area radiotherapy. She died of clinical recurrence after 18 months of treatment. This is the oldest but virgin case, treated with radiation completely, of primitive neuroectodermal tumor located in the vagina reported in the literature.
