A 67-year-old man was admitted with a right lower abdominal tumor. Barium enema and CT scan revealed a large tumor from the cecum to the ascending colon. Colonoscopic biopsy revealed that the tumor was a malignant lymphoma. A laparotomy was performed but the tumor was unresectable because of its invasion into adjacent organs. Then chemotherapy was given via a transarterial catheter with a reservoir. The tumor became smaller after chemotherapy, so a right hemicolectomy was performed. Pathologically, the tumor was non-Hodgkin lymphoma, diffuse medium-sized cell type, according to the Lymphoma Study Group classification. It was positive for the cell surface marker anti B-cell antigen. Resection of the residual tumor after chemotherapy via a transarterial catheter with a reservoir is useful method for treating an unresectable malignant lymphoma of the large intestine.
