A 70-year-old man with bloody bowel discharge resulting in severe anemia was referred to our hospital. Abdominal CT and endoscopic examination revealed a hemorrhagic tumor 3 cm in diameter in the jejunum. Partial resection of the jejunum was performed both as a cure for bowel bleeding and to diagnose the tumor. The resected specimen showed a submucosal tumor measuring 9.5×4.5×4.0 cm projecting into the lumen. Histologically, the tumor comprised spindle cells showing patternless growth and a hemangiopericytoma pattern. Immunohistochemically, tumor cells were positive for bcl-2 and CD99. According to these findings, the tumor was diagnosed as solitary fibrous tumor. The patient showed recurrence in the superior mesenteric plexus, L5 lumbar vertebra, left suprarenal gland, and piriformis muscle 3 months after the operation, and died 5 months postoperatively due to multiple-organ failure. This is a rare case in which SFT of the intestine caused a malignant outcome.
