We report herein on a case of sigmoid colon cancer with intussusception prolapsing through the anus. An 89-year-old woman, diagnosed as having a rectal prolapse was admitted to our hospital because of anal pain, prolapse, and hematochezia. Pelvic CT imaging revealed a target-like lesion in the rectum, and the sigmoid colon was invaginated into the rectum. The intussusception could not be reduced preoperatively. Therefore, a sigmoidectomy via Hartmann's method was performed after reduction by resection of the anterior wall. The patient's postoperative course was uneventful. The cancer was graded as pathologic stage I (pMP, N0, M0). Adult sigmoid colon cancer with intussusception prolapsing through the anus is rare, with only 40 cases reported in Japan.
