[Coexisting malignant lymphoma and early cancer of the stomach]

A 62-year-old man with malignant lymphoma and early gastric cancer as two independent growths in the stomach was reported. In the resected stomach, malignant lymphoma was observed as a protruding lesion measuring 5.5 X 3.0 X 1.2 cm with four giant folds at the anterior wall of the upper gastric body. There also was a poorly differentiated adenocarcinoma as an early gastric cancer of type IIc + III; it measured 0.9 X 0.7 cm and invaded the submucosal layer at the antral portion. There were no pathological findings, excepting intestinal metaplasia, in the mucosal layer between the two lesions. There was no metastasis from either the malignant lymphoma or the adenocarcinoma to perigastric lymph nodes.
