title: Epithelial dysplasia in endoscopic gastric mucosal biopsies.
abstract: To define the frequency of gastric epithelial dysplasia (precancerous lesion), 1463 biopsies from 842 endoscopically studied patients were reassessed. Mild dysplasia was found in 19.9% of the cases, moderate in 4.1%, severe in 0.95%. Since the clinical and biological significance of the lesion is still an open question, indications for follow-up are discussed in the light of personal views, together with a critical evaluation of the recently proposed classifications.
