A 64-year-old woman visited our outpatient clinic because of bloody stools and abdominal fullness. Digital rectal examination revealed a 6 x 4-cm oval mass. Abdominal CT scans demonstrated a concentric, multilayered structure in the rectum. Colonoscopy showed segments of the bowel were dark-purplish, and intussusception. Deeper insertion of the colonoscope through the lumen revealed a type 1 lesion. Under a diagnosis of sigmoid colon cancer with intrarectal intussusception, emergency surgery was performed. The resected specimen showed a type 1 advanced cancer and two early cancers at the base of the intussuscepted colon, all of which appear to have contributed to the intussusception.
