A 75-year-old woman complained of abdominal pain, bloody stools and a tumor prolapsing through the anus. The leading part of the tumor was diagnosed as adenocarcinoma by histological examination. Computed tomograms of the rectal area showed a thickened colonic wall with hyperdense rings which was separated into three layers. The patient was diagnosed as having colo-rectal intussuception secondary to the sigmoid colon cancer, which prolapsed through the anus. Sigmoidectomy by Hartmann's method was performed because of her poor general condition. Adult colo-rectal intussuception prolapsed through the anus is rare, with only 13 cases reported in Japan.

Key words
