Endometriosis externa is presence of endometrial glands and stroma outside uterus. Umbilical endometriosis (also called Villar’s nodules) and subcutaneous endometriosis are rare conditions that occur in elderly women without any menstrual complaints and pelvic endometriosis. The overall incidence of umbilical endometriosis is very low (0.1-0.5%). Here we report a rare case of endometriosis externa with umbilical menstruation in a woman with a previous history of cesarean section and myomectomy. After complete evaluation, the patient underwent excision of the endometriotic lesion with abdominoplasty with mesh repair. The possible cause of this type of endometriosis can be secondary type due to direct implantation of endometrial tissue in the subcutaneous tissue during the previous surgeries.
