Gastric pseudolymphoma.

Six histologically proved cases of gastric pseudolymphoma are described. This uncommon benign condition often simulates ulcerated gastric carcinoma radiologically, and pathologically it may cause considerable confusion with malignant lymphoma. Recognition of this condition is important to prevent unnecessary and often hazardous treatment whether by surgery or radiotherapy and to prevent inclusion in series of malignant gastric lymphoma, so that falsely high survival rates are not recorded.
