Among 121 cases of primary gastric malignant lymphoma from 1962 to 1994 at
the National Cancer Center Hospital, Tokyo, we found four cases (three
males and one female) of adenocarcinoma coexisting in the stomach. The
incidence of gastric malignant lymphoma together with gastric
adenocarcinoma was 3.3%, suggesting that patients with lymphoma may have an
increased incidence of gastric adenocarcinoma. A review of the Japanese
literature revealed an additional 62 patients who developed coexisting
gastric malignant lymphoma and adenocarcinoma. In the total series of 66
patients whose age and sex were recorded, there were 48 males with a mean
age of 63.8 years and 18 females with a mean age of 58.6 years. Most
adenocarcinomas were macroscopically early (76%) and of histologically
differentiated type (75%). Conversely, 71% of lymphomas were of the
advanced type macroscopically. The correct preoperative diagnoses were made
in only 27% (16/59) of cases, when both tumors were located independently.
