54-year-old man underwent a wide resection of the right chest wall because of a tumor which was diagnosed histologically as a malignant fibrous histiocytoma. Five months later, during chemotherapy for lung metastasis, he developed a symptom of upper alimentary tract obstruction. A CT scan showed an intussusception caused by a small intestinal tumor as a leading mass. An operation revealed a jejuno-jejunal intussusception 10 cm in length, 15 cm distal to the duodenojejunal flexure. A round, brittle tumor measuring 5.0×6.7×3.5 cm was found in the resected jejunum. Its cut surface was necrotic and hemorrhagic. Pathological study revealed jejunal metastasis of the malignant fibrous histiocytoma. A metastatic intestinal tumor of malignant fibrous histiocytoma is very rare. This is the 6th case in the Japanese literature. CT scanning is effective for diagnosis of intestinal intussusception.
