Objective: To report a case of endometriosis located at an unusual site in the canal of Nuck.
Design: Case report.
Setting: Department of Obstetrics and Gynecology, Chang Gung Memorial Hospital.
Patient(s): A 35-year-old woman with no previous history of surgery had endometriosis in the canal of Nuck excised incompletely via an open skin method. Recurrent endometriosis at the canal of Nuck was noted 9 months later despite postoperative medical treatment.
Intervention(s): Laparoscopic surgery and open skin method.
Main outcome measure(s): Removal of endometriosis in the canal of Nuck and repair of the inguinal ring.
Result(s): The patent left canal of Nuck identified, endometriosis completely resected, and the inguinal ring closed. She was well 12 months after the second surgery.
Conclusion(s): We suggest that when encountering endometriosis in the canal of Nuck, removing all involved lesions and closing of the internal inguinal ring is indicated.
