Malignant fibrous histiocytoma is a pleomorphic sarcoma in adults, which occurs principally as a mass on an extremity or in the abdominal cavity or retroperitoneum. It typically involved deep fascia or skeletal muscle and only rarely was confined to the subcutis without fascial involvement. Malignant fibrous histiocytomas developed in the intraabdominal organs are very rare and only few cases have been reported until now. Here, we report a case of malignant fibrous histiocytomar developed in the stomach of a 46-year old male who showed clinical and histologic features of malignant fibrous histiocytoma without any identified etiologic factors. The patient was treated successfully with surgery, and has had no recurrence since, during the ensuring one and a half yars.

Adult intusussception is a rare entity and this usually has a definable cause. We describe here two cases of adult patients with ileocolic intussusception that was secondary to a lymphoma of the cecum. The one patient was a 23-year-old man. We diagnosed ileocolic intussusception by performing abdominal computed tomography. At laparotomy, a 5.0 x 5.0 cm polypoid tumor was found in the cecum. Histologic examination disclosed the diffuse large B-cell lymphoma. The other patient was a 32-year-old man. Preoperatively, we diagnosed intussusception in the ileocolic lesion by performing a barium study and computed tomography. At laparotomy, a 3.1 x 4.0 cm tumor was found in cecum, and histologic examination revealed the diffuse small noncleaved type lymphoma (Burkitt's lymphoma). So far as we are aware, this is the first report of a Korean adult patient with intussusception that was secondary to a cecal lymphoma, and it was not secondary to an ileal lymphoma.
