[Gastric lymphosarcoma associated with early carcinoma (type IIa)--a case report].

We report a case of gastric lymphosarcoma associated with early carcinoma (type IIa). Lymphosarcoma was also seen in the small intestine, but there were no metastatic lesions in the lymph nodes , liver, and peritoneum. This suggest that lymphosarcoma was the primary cancer in both the stomach and small intestine. Microscopically, the early carcinoma was a moderately differentiated tubular adenocarcinoma . Only two earlier cases of coexistent gastric lymphosarcoma and early gastric carcinoma have been reported in the literature.
