[A case of gastrointestinal bleeding from metastatic alveolar soft part sarcoma of the jejunum].

Alveolar soft part sarcoma (ASPS) is a rare malignant tumor. It is often seen in the extremities of youngsters, and frequently metastasizes to the lung, brain, and bones. We experienced a case of ASPS which presented with gastrointestinal (GI)bleeding and was diagnosed as metasatic ASPS of the jejunum. We could not find in the literature a single case of ASPS which metastasized to the intestine and caused GI bleeding. We feel that it is important to consider the possibility that metastasis to the intestine can cause GI bleeding in a patient with a history of ASPS.
