Background:
Most umbilical tumors are diagnosed as benign tumors, umbilical metastases of abdominal and pelvic tumors, or Sister Marie Joseph nodule. Herein, we report a case of cutaneous umbilical endometriosis mistaken for a keloid.
Patients And Methods:
A young black woman aged 26 consulted for a painful umbilical tumefaction. She had noted the appearance of a nodule of the umbilicus 10 months ago with bleeding during her menstrual periods. Skin examination revealed a firm and painful umbilical nodule 2.5cm in diameter. She was treated with corticosteroid injections for one month for umbilical keloid. Given that the symptoms recurred regularly at the time of menstruation, we suspected umbilical endometriosis. This diagnosis was finally confirmed by histopathological examination and hormone therapy was instituted on gynecological advice before scheduled surgical excision.
Conclusion:
In a setting of an umbilical tumor simulating a keloid associated with cyclical symptoms in a black woman, the diagnosis of umbilical endometriosis should not be overlooked by the dermatologist.
