Lymphocytic gastritis, abbreviated LG, is a rare form of gastritis, typically associated with celiac disease or Helicobacter pylori infection.
General
The DDx is limited:
- Celiac disease - most common (39 of 82 cases in one series[1]).
- Helicobacter gastritis - common (30 of 82 cases in one series[1]).
- Idiopathic.
- HIV/AIDS.
- Crohn's disease.
- Lymphoma.
Microscopic
Features:[2]
- 25 lymphocytes / 100 epithelial cells.
DDx:
- Helicobacter gastritis - Helicobacter-like organisms present.
- Lymphoma - esp. MALT lymphoma.
