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.
