The review summarizes literature data on rare forms of gastritis and gastopathies. The described gastritis include: lymphocytic, plasmacytic, eosinophilic, granulomatous; a separate group includes gastritis that develop under the influence of external factors: drug-induced, NSAID-induced and post-radiation gastritis. As part of the question of gastropathies, we paid attention to the description of Menetrie's disease, portal hypertensive gastropathy, and GAVE syndrome. We presented materials on the frequency of occurrence of each pathology, etiology, clinical manifestations, morphological and endoscopic diagnostic criteria and consideredthe issues of differential diagnosis and treatment tactics for these diseases.
