A case of umbilical endometriosis

This paper reports a single clinical case of umbilical endometriosis in a 46-year-old woman who developed a small light-brown umbilical nodule without clear trigger 1 year prior, which enlarged and became painful over the subsequent 2 months. The report describes the clinical presentation in the dermatology setting and provides pathological assessment performed by the authors’ pathology department. The main finding is the diagnosis of endometriosis at the umbilicus based on the case workup, but the study is limited by its nature as a single case report, with no broader population analysis or generalizable comparisons. This paper is centrally about endometriosis — specifically a case of umbilical (cutaneous) endometriosis.
