Benign lymphoid hyperplasia of the stomach mimicking gastric malignancy

A case of benign lymphoid hyperplasia of the stomach misdiagnosed as ulcerating gastric carcinoma is presented. The similarities in the clinical, roentgenologic and and gastroscopic features as well as in the gross appearance of the two lesions are described and the features which help differentiation are highlighted. The pathologic picture suggested that the lesion possibly arose as a peptic ulcer and the clinical history further supports such a possibility.
