My aunt had a Brunner's gland tumor removed a few months ago. View at: Google Scholar See in Reference… About 50% are mucosal lesions and 50% are submucosal. To measure the size of Brunner glands in mouse duodenum, approximately 2 cm of the very proximal duodenum (including approximately 0.5 cm of the antrum) was cut open longitudinally, fixed with 4% paraformaldehyde, and embedded on its edge in paraffin. The patient was dis-charged 11days after the surgery. Brunner Gland Hyperplasia (Brunner Gland Hamartoma) Duplication Cyst . The duodenum is the section of gut through which food passes after leaving the stomach. The authors report a case of great Brunner's gland adenoma of the duodenal bulb, which is of interest because of its great size (8.5×4.5 cm) and the negative result of the endoscopic biopsy. In the past, the terms Brunner gland hyperplasia, Brunner gland hamartoma, and Brunner gland adenoma have been used interchangeably causing some confusion in the pathologic classification of these lesions. Brunner’s gland, which was accurately described by Brun-ner in 1688, is a gland in the submucosa of the duodenum (1), which has a main physiological function of secreting an alkaline-based mucus to protect the duodenal lining from the acid secreted in the stomach. Brunner’s gland, which was accurately described by Brun-ner in 1688, is a gland in the submucosa of the duodenum (1), which has a main physiological function of secreting an alkaline-based mucus to protect the duodenal lining from the acid secreted in the stomach. Brunner’s gland hyperplasia is a rare, often benign proliferative disorder of the duodenum [1]. Brunner’s glands, also called duodenal glands, are found in the submucosa of the duodenum, typically in the duodenal bulb and in the second portion of the duodenum proximal to the sphincter of Oddi. The resected specimen contained, on the intestinal surface, one solid, stalked polyp of 2,5 cm (maximum diameter). Nine years later, Brunner (2,3), who was Wepfer’s son-in-law (4), described the duodenal glands in the horse, ox, sheep, deer, dog, and beaver and presented a brief description in man. Brunner’s gland hyperplasia is a type of proliferative disease of the duodenum, which is a very rare case. arising from the Brunner’s gland. 36 Macroscopically, Brunner's gland hyperplasia appears as multiple, sessile, submucosal nodules mostly identified in the duodenal bulb and/or in the second portion of the duodenum. Brunner’s gland adenoma is a rare benign tumor of the duodenum. This is usually in such small amounts that it is not visible, but it can cause anemia and occasionally patients may pass or vomit blood. Their main physiological function is to secrete an alkaline-based mucus to protect the duodenal lining from the acid secreted in the stomach. Most often there are no symptoms, but sometimes abdominal pain occurs at night, or after meals, and there may also be bleeding from the gut. These glands produce alkaline mucus, which neutralizes acid from the stomach as it enters the duodenum. 473–475, 2008. Secretin is secreted by cells in the duodenum when they are exposed to the acidic contents of the emptying stomach. provide an alkaline condition for the intestinal enzymes to be active, thus enabling absorption to take place; provide an alkaline condition for the intestinal enzymes to be active, thus enabling absorption to take place, This page was last edited on 25 August 2020, at 22:06. Brunner's gland adenoma is a rare tumor of the duodenum and might also be an unusual cause of gastrointestinal bleeding or obstruction. - Duct of Brunner’s gland This image of a plica circularis shows evaginations (villi) and invaginations (intestinal glands) of the mucosal epithelium. Brunner’s glands produce a mucus-rich, bicarbonate-containing, alkaline secretion that aids in neutralizing the acidic content of chyme and gastric acid, providing an alkaline milieu to optimize intestinal absorption and lubricate the intestinal walls [1 1. When symptomatic it presents either with duodenal obstruction or bleeding. The endoscopic approach in selective cases appears to be safe, less invasive, and less costly. The Brunner glands, which empty into the intestinal glands, secrete an alkaline fluid composed of mucin, which exerts a physiologic anti-acid function by coating the duodenal epithelium, therefore protecting it from the acid chyme of the stomach. Furthermore, in response to the presence of acid in the duodenum, these glands secrete pepsinogen and urogastrone, which inhibit gastric acid secretion. Cruveilhier was the first to define BG adenomas in 1835 [1 1. It may also present with various symptoms depending on location and tumor size, such as … Herein, we report a case of duodenal carcinoma arising from Brunner’s gland in a 63-year-old man. Brunner's gland adenoma is a rare tumor of the duodenum and might also be an unusual cause of gastrointestinal bleeding or obstruction. The doctors actually couldn't confirm whether it was malignant or not. The cells which make up the glands increase until abnormal numbers are present, forming a tumor. The presence of Brunner’s glands in the submucosa is a diagnostic feature of the duodenum … To measure the size of Brunner glands in mouse duodenum, approximately 2 cm of the very proximal duodenum (including approximately 0.5 cm of the antrum) was cut open longitudinally, fixed with 4% paraformaldehyde, and embedded on its edge in paraffin. This lesion is generally a single pedunculated polyp, with an average size of 2 cm, rarely larger than 5 cm, and locates in the first portion of duodenum [].Its pathogenesis is unknown and malignant change is rarely observed [].
