Objectives:
Primitive neuroectodermal tumor is grouped together with Ewing sarcoma of the bone, but its presentation includes a wider age range and more central locations than its osseous counterpart. Presentation in vagina is exceedingly rare.
Case:
A 34-year-old woman with personal history of kidney transplant presented with a painless vaginal mass. After surgical excision, pathology results demonstrated a primitive neuroectodermal tumor. Chemotherapy was given, followed by external beam and vaginal intracavitary brachytherapy. After 20 months postexcision, there is no clinical nor radiographic evidence of recurrence.
Conclusions:
This is the second case of primitive neuroectodermal tumor located in the vagina reported in the literature.
