[Histo-topography of gastric mucosa changes in benign and malignant stomach diseases].

The incidence and distribution of chronic gastritis, chronicatrophic gastritis and epithelial dysplasia I-III have been investigated in 50 resected stomachs of patients suffering from duodenal ulcer, gastric ulcer, early or advanced gastric cancer. Only in gastric cancer epithelial dysplasia III has been frequently observed, particularly in the neighbourhood of gastric cancer. Distribution of chronic-atrophic gastritis was similar to the distribution of dysplasia I and II. These mucosal lesions were detectable with the same frequency in patients with or without gastric cancer.
