This case report describes a spontaneous occurrence of umbilical endometriosis, which was initially misdiagnosed as an umbilical granuloma and highlights its importance in the differential diagnosis of umbilical lesions.

This paper is a case report describing spontaneous umbilical endometriosis, emphasizing that although umbilical endometriosis is rare (reported as 0.5–1% of extragenital endometriosis), it can arise de novo rather than only after prior surgery. The authors report a patient whose umbilical lesion was diagnosed preoperatively as an umbilical granuloma, and the condition was characterized as spontaneous umbilical endometriosis. A key limitation is that the evidence is limited to a single case, without broader analysis or validation beyond the reported clinical presentation. This paper is centrally about endometriosis — it specifically documents spontaneous umbilical (cutaneous) endometriosis and highlights its diagnostic differential in women with umbilical lesions.

Abstract

Endometriosis is a common gynecological entity that usually occurs in the pelvic organs. Umbilical endometriosis is a rare condition that accounts for 0.5-1% of all extragenital endometriosis. It usually arises secondary to prior surgery but may arise de novo as well. We report a case of this condition with the spontaneous occurrence, which was diagnosed preoperatively as umbilical granuloma. Umbilical endometriosis should be kept in differential diagnoses in women with umbilical lesions.
