A 79-year-old man was admitted to our hospital with complaints of tarry stools and anemia. Emergency endoscopic examination of the stomach revealed 3 distinct malignant ulcerating lesions. Biopsy specimens showed poorly differentiated adenocarcinomas and gastrectomy was performed. The histopathological diagnosis was malignant hemangioen-dothelioma (angiosarcoma). Five months later, he appeared complained of anal bleeding and colonoscopy demonstrated bleeding from polypoid lesion of the rectum, and poly-pectomy was performed. The histopathological finding was also angiosarcoma. Followed-up examination showed the recurrence in anastomotic region of the residual stomach, the cecum and ascending colon. Multif ocal angiosarcome of the stomach and colon is a very rare occurrence. As multifocal malignant hemangioendothelioma of the gastrointestinal tract is extremely rare, was reported this case with a review of literatures.
