[Histologic and cytologic evaluation of chronic gastritis].

It is in the gastrobiopsies that morphological features of chronic gastritis--inflammation and activity according to the International Classification of Gastritis (1990)--are more pronounced in the atypical hyperplasia and dysplasia than in normal epithelium. This means that inflammatory cells may play a role in the development of atypical hyperplasia and moderate dysplasia. Nuclear-cytoplasmic ratio in cases of the foveolar epithelium dysplasia was 0.89 and in the dysplasia of the metaplastic epithelium of intestinal type it was 0.99, this being higher than in normal epithelium. Complete intestinal metaplasia was large-focal or diffuse, while incomplete was predominantly small-focal.
