RESUMEN
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.
