title: Umbilical endometriosis.
abstract: A 41-year-old woman with umbilical endometriosis is presented. The umbilical lesion is repeatedly painful and there is a bloody discharge simultaneous with the menstrual period. Treatment of umbilical endometriosis is by excision. Hormonal therapy results in its incomplete regression. Umbilical endometriosis is a very rare disease, but should be considered in the differential diagnosis of umbilical tumors.
