Umbilical Endometriosis Following Laparoscopic Cholecystectomy

Endometriosis is a painful disorder that most commonly causes dysmenorrhea and pelvic pain. It is defined as endometrial glands and stroma that occur outside of the uterus. Typically the lesions are located and contained within the pelvic cavity, however it can occur at multiple sites throughout the body. Here is a 28-year-old female who presents to an outpatient family medicine clinic with endometriosis of her umbilicus. CT scan revealed a 2-cm mass protruding continually through the umbilical stalk. The mass was then resected and pathology confirmed it to be consistent with endometriosis. Umbilical endometriosis is a rather rare finding, but still likely. This case presents differently due to the fact that the patient has never had a previous history of endometriosis or associated symptoms. The most likely suspected mechanism of the umbilical endometriosis would be the laparoscopic cholecystectomy done one year prior.
