Isolierte umbilikale Endometriose – ein Fallbericht
This case report describes a rare instance of isolated umbilical endometriosis, a specific extragenital manifestation occurring in approximately 0.5–1% of all endometriosis cases.

This case report describes a 34-year-old nulliparous woman presenting with a painful, dark red soft tissue tumor at the umbilicus that exhibited histologically confirmed endometriosis. Despite an unremarkable gynecological history and ultrasound findings, initial excision resulted in cyclical bleeding, necessitating a second surgery for complete removal of the residual lesion while laparoscopy ruled out pelvic disease. The authors note that isolated umbilical endometriosis is rare, accounting for less than one percent of extragenital cases, and may arise from metaplasia of urachal remnants rather than surgical scar tissue. This paper is centrally about endometriosis — specifically the clinical presentation, diagnosis, and surgical management of isolated umbilical endometriosis.
