Endometriosis of the Appendix: Incidental Diagnosis

Abstract Background: Endometriosis of appendix is a very rare condition. Its recognition at the time of surgery is important for complete treatment. Case: The case of a young woman who had presented with pain lower abdomen and mennorhagia, is reported. Preoperative diagnosis was ovarian cyst. Diagnosis of appendicular endometriosis was incidental. The patient was found to have an ovarian cyst adherent to the appendix, and a total abdominal hysterectomy, bilateral salpingo-oophrectomy, and appendectomy were performed. Results: The patient had an uneventful recovery, and she was free of pain on follow-up. Conclusions: The possibility of appendicular endometriosis should always be kept in mind when operating to treat right lower-quadrant pain or for endometriosis. (J GYNECOL SURG 28:138)
