Follicular Lymphoid Hyperplasia.

 (Goose pimple stomach).

 The lesions are raised, flat or nodular folds, and are often
 associated with gastric ulceration. The etiology of this
 condition remains unclear, but Helicobacter pylori infection
 has been implicated. Microerosions are frequently seen
 with magnifying endoscopes.

Endoscopic View of Follicular Lymphoid Hyperplasia.

 In follicular gastritis, gastric acidity is significantly reduced,
 but can be normalized by eradication of H. pylori. It can
 thus be speculated that inflammatory cytokines or H. pylori
-infection induced prostaglandins might strongly inhibit
 gastric acid secretion in follicular gastritis.

Follicular Lymphoid Hyperplasia.

 Innumerable small hemispherical elevations, many with a
 slightly depressed or umbilicated center, are characteristic
 of follicular gastritis.

Follicular Lymphoid Hyperplasia.

 Diffuse hyperplasia of lymphoid follicles at the antrum.
 (Goose pimple stomach).

 Proliferation of submucosal lymphoid follicles in the
 gastrointestinal tract. Lymph follicles are a normal
 component of gut associated lymphatic tissue.
