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)
