Abstract
Some healing gastric ulcers leave an elevated scar that is indistinguishable from early gastric cancer type lla during short term observation. We have followed 9 patients with elevated ulcer scars by radiography, endoscopy, and biopsy. The appearance is that of mucosal folds converging to an elevated center and resembles early gastric cancer. Histologic sections reveal penetration of the muscularis mucosae and submucosal fibrosis; the central elevation consists of hyperplastic pyloric glands with cystic dilatation.
