Lymphocytic gastritis and giant gastric folds associated with gastrointestinal protein loss

Lymphocytic gastritis is a recently described lesion which occurs in a significant proportion of patients with celiac sprue. This paper describes two patients with lymphocytic gastritis and no evidence of celiac sprue. Both patients had markedly enlarged gastric folds and serum hypoproteinemia, which were clinically suggestive of Ménétrier's disease. These cases indicate that lymphocytic gastritis may cause a protein-losing gastropathy and should be considered in the differential diagnosis of Ménétrier's disease.
