Etiology:

- Consumption of aspirin and other nonsteroidal
anti-inflammatory drugs.
- Chronic alcohol ingestion
- Alkaline or bile reflux(abnormal pyloric sphincter function,
previous surgical intervention)
- Uraemia

Microscopic features:

- Glandular elongation and tortuosity
- Mucin depletion
- Edema
- Hypercellularity of the gastric pits
- Foveolar hyperplasia
- Increased number of smooth muscle fibres in lamina propria.
- Villiform transformation of the mucosa
- Regenerative (basophilic) glands with increased mitotic activity.
-Capillary congestion and vasodilation in superficial lamina propria
- A few chronic inflammatory cells and occasional neutrophils.
- Usually there is no evidence of atrophy.
- Bile in the glands.
- Long standing bile reflux cases may be accompanied by erosions or intestinal metaplasia (including all its subtypes).


Note :  Reactive gastritis with erosions is the commonest cause of false positive diagnosis of dysplasia or carcinoma in the stomach.
