Presentations

Microscopic evaluation

Generally screen for gastritis:

  • Mild acute gastritis:[1]
  • Modest edema of lamina propria
  • Vascular congestion
  • Scattered neutrophils
  • Mucosal hemorrhage
  • Intact epithelium
  • Moderate to severe acute gastritis:[1]
  • Loss of superficial epithelium above the muscularis mucosa
  • Hemorrhage
  • Variable infiltrate with neutrophils
  • Fibrinopurulent luminal exudate
  • Nearby epithelium may show regenerative changes
  • Chronic gastritis[2]
  • Presence of plasma cells, lymphocytes, and occasionally lymphoid follicles
  • Eosinophils and neutrophils may be present
  • Reduced mucin in the cytoplasm
  • Enlargement of nuclei and nucleoi
  • Subnuclear vacuolation in antral glands or pits (which is PAS negative)
  • Intestinal metaplasia: with partial replacement of the mucosa of the antrum and body with metaplastic goblet cells of intestinal morphology, absorptive cells and Paneth cells
