A 53-year old woman was admitted for further examination of an abdominal tumor that was found by abdominal computed tomography (CT) and Ultrasonography. It was a solid and cystic tumor 30 cm in diameter arising from the mesenterium. Angiography showed feeding vessels from the superior mesenteric artery and encasement of this artery. Preoperative echo-guided aspiration cytology showed no cytological diagnosis. We extirpated the tumor and resected the transverse colon, ascending colon and jejunal segment. The tumor was histologically malignant fibrous histiocytoma and immunohistochemically positive for α₁-antichymotrypsin. The recurrence tumor in the abdominal cavity was developed 4 months later. The tumor was removed by the second surgery. Postoperative chemotherapy was not initiated and the woman was alive and well recurrence-free for 13 years after the second operation.
