The Brunner's gland polyps are composed of hyperplastic Brunner's glands with intervening fibrous bands and connective tissue stroma that contains a mixture of ducts, adipose tissues and smooth muscles.
The pathogenesis of Brunner's gland adenomas is unknown; it is thought to be the result of increased acid exposure resulting in hyperplasia of the Brunner's glands.

The origin, development and differentiation of Brunner's glands
in the rat.
Based on the imaging and pathological studies, we diagnosed the duodenal tumor as adenocarcinoma arising from Brunner's glands. Due to the advanced age and multiple underlying disorders, the risks of general anesthesia, artificial ventilation, and radical surgical resection were considered too high.
Pathological analysis of the resected specimen revealed proliferation of Brunner's glands (Figures 4(a) and 4(b)).
Microscopically, the lesion showed marked proliferation of Brunner's glands, extending up towards the antrum of the stomach (Figures 3(a), 3(b), and 3(c)).

hyperplasia, an unusual cause of hemorrhagic shock.
Histological examination confirmed Brunner's gland
hyperplasia, with lobular proliferation of Brunner's glands
, some of which were cystically dilated.
SUMMARY: The existence of Brunner's glands
(BGs) in the duodenal submucosa is uncontestable, but their exact distribution along the full extent of the duodenal wall is unknown.
