Simultaneous occurrence of malignant lymphoma and malignant gastric cancer in a single patient is rare. Such cases may be positive or negative for H. pylori infection. A 60-year-old-man was examined at our clinic for evaluation of abnormal shadows in upper gastrointestinal radiography. Endoscopy of the upper gastrointestinal tract revealed early cancer in the fornix and mucosa-associated lymphoid-tissue (MALT) in the antrum of the stomach. At Toranomon Hospital, endoscopic submucosal dissection (ESD) was performed under a diagnosis of early gastric carcinoma. Histological findings for the upper gastric lesion were compatible with early moderately differentiated tubular adenocarcinoma of type 0-IIc, while those for the lesion in the antrum corresponded to MALT lymphoma. H. pylori was detected. The patient declined surgery and is currently under close observation. H. pylori infection may have had a major role in the development of adenocarcinoma of the stomach and MALT in this case.
