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
