Background

Polypoid endometriosis (PEM) is a rare type of endometriosis, frequently mimicking a malignant tumor. We report on a patient with PEM over a 10-year span who had symptoms at age 16.

Case

A 20-year-old woman presented with massive vaginal hemorrhage and spontaneous abortion, having symptoms of dysmenorrhea, anal distending pain, and vaginal bleeding since adolescence. Imaging showed multiple polypoid neoplasms of the rectum and vagina connecting to the huge mass in a cul de sac. After exploration and excision, the pathology revealed PEM.
