Angiosarcoma of cecum: unusual presentation with intussusception.

We report a 55-year-old man with angiosarcoma of the cecum who presented with generalized colicky abdominal pain with a mass in the periumbilical region. The lesion at surgery was a colo-colic intussusception extending to the midtransverse colon. A radical right hemicolectomy was done. Metastases to regional lymph nodes were noted in the specimen.
