[Gastric mucosal cysts as a histomorphological equivalent to polypoid gastric mucosal lesions].

Report on a 57-year-old female patient with numerous polypoid lesions of the gastric mucosa. This aspect has been described only recently and it is not listed in the scheme of classification of gastric polyps, usual up to now. This clinical picture is histomorphologically characterized by multiple cysts of varying size within an otherwise intact and non-inflammatory glandular body of the corpus mucosa. No relation to the so-called cystic gastritis can be detected. Etiology and pathogenesis are unknown. A doubtful hamartoma or a functional secretory disorder are discussed.
