抄録

A 77-year-old woman was admitted to the hospital because of an upper abdominal mass. Abdominal ultrasonography, computed tomography, hypotonic duodenography, angiography and Garium scintigraphy suggested a malignant tumor in the mesentery of duodenojejunal flexure. The tumor combined with the third portion of the doudenum and the origin of the jejunum was resected. Pathological diagnosis was malignant lymphoma of non-Hogkin's diffuse large B cell type. Immunohistochemical examination showed negative BCL-2 staining. Molecular cytogenic analysis disclosed chromosome translocation t (8; 22) (q24; q11), but no C-MYC abnormalities recurred. Based on these findings, no other treatments following surgery were added. The patient has been in good health as of six months after the surgery.<br> Surgical resection of a tumor is useful for mesenteric malignant lymphoma in respect that exact diagnosis and appropriate therapeutic principle could be established through close exploration of the resected specimen including prognostic fuctors.
