Definition / general
  • Sometimes known as multifocal atrophic gastritis; formerly environmental gastritis
  • Chronic gastritis accompanied by glandular atrophy (mild, moderate, severe), usually secondary to chronic H. pylori infection
  • Initially glands are compressed, later they are destroyed, loss of acid leads to conditions conducive to bacterial growth
  • Associated with duodenal ulcer, gastric peptic ulcer
  • Degree of atrophy and intestinal metaplasia are correlated (Hum Pathol 2001;32:31)
  • Epithelial changes may become dysplastic and progress to carcinoma
Gross description
  • Thin, smooth mucosa (without rugae), prominent submucosal vessels (due to mucosal atrophy)
