Primary umbilical endometriosis: a case report

Abstract

Umbilical endometriosis is a rare presentation especially in the absence of prior pelvic surgery. This report presents a rare case of symptomatic primary umbilical endometriosis in a 28 year old female who presented with a 2 year history of umbilical mass associated with cyclical bleeding at the time of her menses. There was no previous history of abdominal or pelvic surgery and no history of endometriosis associated symptoms. An excisional biopsy was performed with histology confirming the diagnosis of endometriosis.
