A 24-year-old student presented with a cyclically painful and bleeding umbilical mass, which was surgically excised and histologically confirmed as umbilical endometriosis.

This paper describes a case report of umbilical endometriosis in a 24-year-old student who had a 3-year history of a painful umbilical mass that bled cyclically with menstruation, with a normal pelvic ultrasound and no family history of endometriosis. The authors assessed the lesion based on its cyclical swelling, pain, and bleeding patterns, then performed surgical excision of the mass with subsequent histological confirmation showing benign endometrial-type glands and stroma without malignancy. The paper notes that umbilical endometriosis is rare and requires a high index of suspicion, and it acknowledges limited diagnostic certainty from symptoms alone since clinical appearance can vary and ultrasound findings were normal in this case. This paper is centrally about endometriosis — it focuses specifically on umbilical endometriosis as a rare extrapelvic manifestation.

Abstract

Endometriosis is a rare condition in which there is growth of endometrial tissue outside the lining of the uterus. We report the case of a 24-year-old, unmarried student of the local university who presented with an umbilical mass that was painful and bled cyclically with the onset of her menstruation. She previously had a laparotomy on account of a ruptured tubal ectopic pregnancy, and there was no family history of endometriosis. A pelvic ultrasound was normal. On the basis of cyclical bleeding, swelling, and pain that coincided with her menstruation, an assessment of umbilical endometriosis was made, and she subsequently had a surgical excision of the mass with subsequent histological confirmation of the condition. Umbilical endometriosis is a rare condition, and there must be a high level of suspicion to diagnose this condition.
