Abstract

Intestinal endometriosis is often not suspected preoperatively in patients without a past history of this condition. Accurate preoperative diagnosis is very difficult due to the absence of specific clinical symptoms or endoscopic features. A 39-year-old woman with clinical and endoscopic findings consistent with a protruding demarcated mass invasive into the rectosigmoid colon underwent tumor resection under the suspicion of rectosigmoid cancer. However, final histological findings revealed benign endometriosis of the sigmoid colon. If a patient experiences weight loss, change in bowel habits, and a mass in the colon, the overwhelming likelihood is adenocarcinoma of the colon; however, intestinal endometriosis mimicking rectosigmoid cancer should also be considered.
