Lymphoreticular hyperplasia of the stomach (pseudolymphoma).
Three histologically proved cases of gastric lymphoreticular hyperplasia with long term follow-up are reported. This condition is often confused radiologically with ulcerating carcinoma and pathologically with malignant lymphoma. The presence of a large ulcer surrounded by a mass and associated with thick rugal folds and additional gastric or duodenal ulcers is not diagnostic but should suggest the possibility of this condition.
