Inflammation of the stomach:
Contents
Microscopy evaluation
- Mild acute gastritis:[2]
- Modest edema of lamina propria
- Vascular congestion
- Scattered neutrophils
- Mucosal hemorrhage
- Intact epithelium
Early acute superficial gastritis: Marked neutrophilic infiltrates appear in the mucous neck region and lamina with a pit micoabscess.[1]
- Moderate to severe acute gastritis:[2]
- Loss of superficial epithelium above the muscularis mucosa
- Hemorrhage
- Variable infiltrate with neutrophils
- Fibrinopurulent luminal exudate
- Nearby epithelium may show regenerative changes
- Chronic gastritis[3]
- 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.
Extensive atrophy of oxyntic glands in fundus/corpus causes pseudo-pyloric metaplasia.[1]
When gastritis is present, also evaluate as a stomach biopsy for Helicobacter pylori.
Microscopy report
Chronic gastritis without neutrophils is preferably also termed "non-active".
Example:
(Gastric, biopsy:) Mild chronic non-active gastritis, non-specific. Negative for Helicobacter pylori organisms on H&E slide. |
Notes
- ↑ The combination of atrophy and gastritis helps the clinician to potentially make a diagnosis of atrophic gastritis.
