Abstract
Umbilical endometriosis is defined as an ectopic localization of functional endometrium at the level of the umbilicus. It is a rare condition, representing 0.5% to 1% of all extragenital endometriosis cases, and its pathophysiology is poorly understood. We report the case of a 34-year-old woman, G2P2, with no significant surgical history, admitted for cyclic umbilical pain. Physical examination revealed a grayish nodule at the umbilicus and MRI showed a parietal umbilical nodule suggestive of an endometrioma. The patient underwent resection of the umbilical nodule and the definitive histological study confirmed endometriosis.
