title: A case of ileoileal intussusception caused by metastatic pedunculated tumor of cutaneous angiosarcoma.
abstract: Cutaneous angiosarcoma is a rare aggressive vascular tumor that occurs in elderly patients and is usually located on the head and face. Metastases often develop in the cervical lymph nodes, lungs, bone, liver and spleen. There have been no reports of ileoileal intussusception due to metastatic tumor from cutaneous angiosarcoma. We reported a case of cutaneous angiosarcoma in a 67-year-old Japanese male accompanied with ileoileal intussusception due to metastatic angiosarcoma. We assume that the metastatic tumor in the small intestine was metastasized hematogeneously from cutaneous angiosarcoma, resulting in the formation of nodules and the rapid growth of a pedunculated tumor as a forerunner of the ileoileal intessusception.
