Scar endometriosis as a complication of surgically treated utero-cutaneous fistula

Extra-pelvic endometriosis is a rare form of endometriosis, however cesarean section scar is a common site for the rare condition. Scar endometriosis can be associated with obstetric or gynecologic surgeries. Utero-cutaneous fistula is an abnormal communication between the endometrium and the skin, this is another rare clinical condition that may complicate cesarean section. We report a case of a 23-year-old woman presenting with features suggestive of scar endometriosis about 20 months after surgical treatment of utero-cutaneous fistula. The utero-cutaneous fistula developed 2 months after cesarean section. This case is presented to highlight scar endometriosis as a complication of surgical management of utero-cutaneous fistula and emphasize the importance of complete surgical excision in the management of both rare conditions.
