This paper reports a rare case of umbilical endometriosis in a 45-year-old woman who presented with a painful brown, pigmented umbilical tumor that increased in symptoms during menstruation. The authors suspected umbilical endometriosis, excised the lesion, and histology confirmed endometriosis; the resected mass measured about 20 mm by 20 mm with a grayish-white cut surface. They note that recurrence was not observed one year after surgery, following “nasal suprecur” administration. The paper emphasizes that umbilical endometriosis accounts for about 0.3–3.0% of all endometriosis and that only 42 cases had been reported in Japan including this one. This paper is centrally about endometriosis — specifically an umbilical endometriosis case.

Abstract

A case of umbilical endometriosis was reported for its rarity. A 45-year-old woman, who had experienced 2 times pregnancies and 2 times labors, was hospitalized with umbilical tumor. The tumor was about 1.5 cm in diameter, hard and pigmented in brown, and had become painful and reddened during menstration. Umbilical endometriosis was suspected, and tumor was excised. Resected material was elastic hard in consistency, 20 mm×20 mm in size, and its cut surface was grayish-white and parenchymal. Histological diagnosis was endometriosis. Recurrence is not observed with nasal suprecur administration a year after surgery.Umbilical endometriosis is very rare. It comprises of 0.3-3.0% of all endometriosis, and only 42 cases have been reported in Japan including present case. However, as endometriosis is most common in umbilical tumors in female, a history should carefully be taken regarding the exacerbation of symptoms at menstruction.
