We evaluated the changes over 1â55 months in mild gastric epithelial dysplasia (a relatively frequent, but not widely studied histological lesion) in 20 patients (11 with benign gastric ulcer, eight with chronic gastritis, and one after Billroth 2 operation), in order to ascertain whether to follow-up such patients in the future. Regression of the lesion was documented in 13 (65%), and no change in six (30%). Progression from mild to moderate dysplasia occurred in only one patient (5%). As mild dysplasia regresses or remains unchanged in most patients, at least over the short-term, specific follow-up is probably unnecessary. Nevertheless, a rational program of monitoring the associated precancerous conditions is in order. Â© Lippincott-Raven Publishers.
