[A case of coexistent multiple malignant lymphomas and early carcinoma of the stomach]

A 68-year-old man with multiple malignant lymphomas and early gastric carcinoma in the stomach is described. In the resected stomach, six lesions of malignant lymphoma, large cell type (LSG classification) or histiocytic type (Rappaport classification) were observed at the posterior wall of the gastric body. Well differentiated tubular adenocarcinoma as an early carcinoma of type IIc was also found on the lesser curvature of the gastric body. In addition, multiple early follicular proliferation of malignant lymphoma was microscopically revealed centering around the gastric body. This rare case of coexistent multiple malignant lymphomas and early carcinoma of the stomach is reported and discussed.
