Examination of the small intestinal trac t revealed a tumor with calcification in the inner portion, from the horizo ntal portion to the ascending portion of the duodenum, and jejunojejunostom y was performed. The pathological findings of the tumor gave a diagnosis of non-Hodgkin's lymphoma, diffuse small cleaved cell (Working Formulation cl assification), B cell type, of the jejunum, Calcification is rarely found i n untreated malignant lymphoma and 15 cases of untreated malignant lymphoma with calcification have been reviewed.
