Study Notes


  • Acute gastritis can be caused by non-infective factors, including irritation from:
    • Drugs such as aspirin (NSAIDs) and chemotherapy
    • Smoking and alcoholism

Features of Gastritis

  • Gastritis can be classified into three types based on the location of inflammation:
    • Antral predominant
    • Corpus predominant
    • Pangastritis (inflammation of the entire stomach wall)

Chronic Gastritis

  • There are two types of chronic gastritis:
    • Chronic superficial gastritis
    • Chronic atrophic gastritis

Morphological Features of Chronic Gastritis

  • Mucosa:
    • Slight flattening of gastric rugae in chronic superficial gastritis
    • More thinned and flattened, and red in chronic atrophic gastritis

Microscopic Features of Chronic Gastritis

  • Inflammation is limited to the inner 1/3 of the mucosa (in the lamina propria) with:
    • Mixed lymphocytes
    • Plasma cells
    • Few neutrophils
    • Eosinophils
