Endometriosis of the umbilicus is rare, and account for about 0.2% of all endometriosisexterna. We report a case of endometriosis of the umbilicus with a review of the literature. A 47-year-old woman was seen at the hospital because of umbilical pain and bloody discharge from the umbilicus throughout menstrual period. A spherical mass, 1cm in diameter with slight tender, was palpable around the umbilical region. Abdominal CT scan revealed a solid tumor 12mm in diameter. Based on the clinical symptoms and histopathological features of the biopsied specimen, we diagnosed the tumor as endometriosis of the umbilicus. Under general anesthesia, an enucleation of the tumor was performed. It was diagnosed as endometriosis histopathologically. There have been no signs of the recurrence after the operation.
