title: [A case of primary angiosarcoma of small intestine presenting as recurrent gastrointestinal bleeding].
abstract: Angiosarcoma is a rare malignant tumor which occurs frequently in the skin and soft subcutis. Moreover, primary gastrointestinal angiosarcomas are very rare. This tumor manifests as non-specific symptoms such as gastrointestinal bleeding, abdominal pain and nausea. The diagnosis is often made at an advanced stage. Surgery, chemotherapy and radiotherapy are the mainstay of treatment. However, the prognosis is very poor. We report a case of primary angiosarcoma of the small intestine presenting as recurrent gastrointestinal bleeding. A 54-year-old man was admitted with recurrent gastrointestinal bleeding. An abdominal CT scan revealed an ileo-ileal intussusception. Segmental resection was performed with ileo-ileal anastomosis. The ileal mass was diagnosed as angiosarcoma on immunohistochemical stain. He received 3 cycles of chemotherapy, but died 5 months after the diagnosis.
