title: Hypertrophic gastritis, primary diffuse G-cell hyperplasia and pancreatic metaplasia of the gastric mucosa (pseudo-Zollinger-Ellison syndrome)--case report.
abstract: We report a case of pseudo-Zollinger-Ellison syndrome in a 17-year-old man presenting with gastrin levels exceeding 2000 pmol/l and BAO 24 mEq/hr. Histologically, apart from hypertrophic gastritis with the thickening of mucosal folds and diffuse G-cell hyperplasia, gastric mucosa was found to contain foci of pancreatic metaplasia.
