Chronic gastritis: a clinico-pathological classification.

Abstract

Based on known histopathologic features, as well as clinical and etiopathogenic information, a classification of chronic gastritis is proposed. The following types are described: superficial gastritis, diffuse antral gastritis, postgastrectomy (reflux) gastritis, diffuse corporal atrophic gastritis, and multifocal atrophic gastritis. The histopathologic features are illustrated, and the main clinical features are discussed.
