A Case of H. pylori-associated Granulomatous Gastritis with Hypertrophic Gastropathy.

A 46-year-old man had chronic granulomatous gastritis characterized by giant gastric folds with noncaseating epithelioid granulomas including giant cells in the corpus. No definite etiologic factors were detected. Histology and the rapid urease test indicated that H. pylori was present in both the antrum and corpus. The granulomatous gastritis with giant gastric folds improved after H. pylori eradication. This case suggests an association between isolated granulomatous gastritis and H. pylori infection.
