In short


Ménétrier’s disease

Ménétrier’s disease is premalignant and presents with hypoproteinemia and anemia.
Foveolar hyperplasia that often results in mucosal thickness 1 cm or greater is the most striking feature of MD.


Lymphocytic gastritis

Lymphocytic gastritis is characterized by the infiltration of the gastric mucosa by T cells and is probably associated with H. pylori infection.


Granulomatous gastritis

Granulomatous gastritis is seen rarely in Crohn’s disease and also may be associated with tuberculosis.


H. pylori

One of the characteristics of H. pylori is its ability to hydrolyse urea, resulting in the production of ammonia, a strong alkali. The effect of ammonia on the antral G cells is to cause the release of gastrin via the previously described negative-feedback loop.
