title: Angiosarcoma of the small intestine: a case report and literature review.
abstract: A case of primary intestinal angiosarcoma in a 59-yr-old man is reported. The patient had recurrent gastrointestinal bleeding with normal upper and lower gastrointestinal endoscopies, technetium-99m-labeled erythrocyte scan, and angiography. Barium small bowel series and abdominal computerized tomography showed an ileal mass. Pathological examination was consistent with hemangiosarcoma with both solid and vasoformative patterns. Metastatic disease was also identified in the small bowel mesentery, liver, spleen, lungs, and brain. No identifiable underlying or epidemiologic factors have previously been reported to be associated with this rare type of tumor of the gastrointestinal tract. The pertinent literature on gastrointestinal angiosarcoma also is reviewed.
