Brunner’s gland hamartoma, also known as Brunner’s gland adenoma or brunneroma, comprises a small portion of these benign tumors. B enign small bowel neoplasms are very rare. The pathology of the current case, which included multilocular cysts lined by columnar epithelium, dilated ducts, and lymphoid cells heavily infiltrated by germinal centers, also included a secondary retention cyst that was caused by an obstruction of the major Brunner’s gland duct as well as hyperplasia of Brunner’s glands. 13. The purpose of this essay is to describe, illustrate, and correlate the imaging and pathologic features of Brunner's gland hyperplasia and Brunner's gland hamartoma. Brunner's gland hyperplasia. Surgical evaluation also revealed ulcerations of the mucosa surrounding the polyp, which were thought to be the cause of his iron deficiency anemia. The oxyntic mucosa show marked hyperplasia and hypertrophy of the parietal cells.Some of these cells can be vacuolated, and many can display protrusions of apical cytoplasm into dilated oxyntic glands filled with inspissated eosinophilic material.. Etiology. Where the diameter of focal hyperplasia is less than 1 cm, the term Brunner gland hyperplasia is used.. Etiology remains obscure. Except for its association with duodenal ulcers, Brunner’s gland hyperplasia has no clinical significance and mostly asymptomatic. Rarely, they may be found in the second [27%] and third [5%] parts of the duodenum, the pyloric canal [5%], the fourth part of the duodenum, jejunum and proximal ileum. Excessive nodular hyperplasia of Brunner glands associated with gastric hypersecretion and lipomatous atrophy of the pancreas. Brunner gland hamartoma/hyperplasia) can be differentiated from PGAs primarily by their retained lobular architecture. CONCLUSION. Tøttrup A(1), Rokkjaer M, Kruse A, Poulsen SS, Jacobsen NO. The aetiology of these lesions is not yet clear. Brunner's gland hamartoma typically appears as a polypoid, pedunculated lesion ranging in size from 0.7 to 12 cm, with a mean of 4 cm [ 1 ]. Sebaceous gland hyperplasia is characterized by large sebaceous glands with increased numbers of cells forming numerous lobules around central ducts ( Figure 3 and Figure 4). Background . Brunner gland hyperplasia results from disproportionate overgrowth of Brunner glands in the duodenum as a result of hyperacidity.. Hyperplasia begins at the pylorus and extends distally within the first 2/3 rds of the duodenum. Several features of these lesions favor their designation as hamartomas , including the lack of encapsulation; the mixture of acini, smooth muscles, adipose tissue, Paneth cells, and mucosal glands; and the lack of any cell atypia. Awareness of the existence and character of Brunner’s gland lesions will increase the possibility of their accurate diagnosis. 12. Author information: (1)Dept. Brunner’s gland hyperplasia is a rare cause of biliary obstruction and pancreatitis and the literature is limited to a few case reports [3, 4]. The proliferative lesions of the Brunner’s glands (BGs) are hyperplasia and hamartomas, and they are usually asymptomatic and very rarely diagnosed. The observed mucosal patterns could be classified into five categories: (1) focal BGH causing a solitary submucosal adenoma or a cluster of sessile polyps in the otherwise smooth duodenal bulb surface … Acute duodenitis. Hyperplasia of Brunner glands with a lesion greater than 1 cm was initially described as a Brunner gland adenoma. Background Brunner’s glands are exocrine glands located in proximal duodenum. Images Rarely one or few hyperplastic Brunner’s glands may form a mass lesion large enough to cause obstructive symptoms, epigastric pain, or upper GI bleeding. Hyperplasia of Brunner glands with a lesion greater than 1 cm was initially described as a Brunner gland adenoma. Herein, we report a case of duodenal carcinoma arising from Brunner’s gland in a 63-year-old man.

Hyperplasia of Brunner's glands: report of a case and review of the literature. [citation needed] DDx: Chronic duodenitis not otherwise specified - no foveolar metaplasia, abundant plasma cells. Pathology revealed Brunner's gland hyperplasia with secondary polyp formation that extended to the margin. • Hyperplasia of the parietal cells due to increased gastrin production • Source of gastrin may be: – A pancreatic islet cell tumor (90%) – A proximal duodenal tumor (7%) – Antral G-cell hyperplasia (3%) • Maximal stimulation of parietal cells leads to excessive acid production, Radiographic features of the duodenal mucosa were analyzed in a series of 26 patients in whom the diagnosis of Brunner gland hyperplasis (BGH) had been established by endoscopic biopsies. ... Brunner's gland adenoma (hyperplasia) (BGA/H) is a benign gastrointestinal lesion, usually asymptomatic and frequently detected incidentally by endoscopy as a submucosal nodule. Over the period of a 2-year study, sebaceous hyperplasia has the potential to progress to benign and malignant sebaceous cell neoplasms. Because these glands function to buffer the acid output of the stomach, it has been postulated that Brunner’s gland hyperplasia (and, by extension, Brunner’s gland hamar-tomas) may be due to hyperchlorhydria (10,11). Introduction: BPH or benign prostatic hypertrophy or Nodular hyperplasia of prostate is a condition characterised by the enlargement of prostate especially in the peri-urethral regions of … Dodd GD, Fishier JS. Nodular Hyperplasia of Bartholin Gland is a very uncommon nodular lesion that is caused by a benign growth of the Bartholin gland. Brunner's gland hyperplasia is a rare benign lesion of the duodenum and is usually found incidentally. Reactive Brunner gland proliferative lesions (e.g. Erb WH, Johnson TA.

Key words: Brunner’s gland hyperplasia, EUS-FNB, ESD, LECS (Intern Med 58: 2009-2013, 2019) (DOI: 10.2169/internalmedicine.2477-18) Introduction Brunner’s gland hyperplasia (BGH) is basically a benign polyp lesion that is mainly limited to the first part of the duodenum, and it frequently is associated with duodenal ul- chronic omeprazole therapy () … Buchanan EB. Brunner's gland adenoma (BGA) of the duodenum appear to be nodular hyperplasia of the normal Brunner's gland with an unusual admixture of normal tissues, including ducts, adipose tissue and … Surgical pathology showed Brunner’s gland hyperplasia and was negative for malignancy. It is agreed among pathologists that Brunner gland hyperplasia and Brunner gland hamartoma have a common cause, and that the distinction between the two is arbitrary. Radiology 1953;60:814. Introduction The small intestine constitutes 75% of the gastrointestinal tract; however, small intestine tumors are extremely rare (5%), with duodenal tumors being more common than jejunal and ileal tumors [1] . They tend to be 1-2 cm in diameter, although case reports have described tumors of up to 12 cm diameter. However, many studies have associated this condition with acid hypersecretion, chronic pancreatitis, uremia, and H. pylori infection. Gastric heterotopia of the duodenum. We report 3 patients and review the recent literature to support our hypothesis of common pathology. The pathogenesis of Brunner’s gland hyperplasia remains unknown. [citation needed] Ulceration. Brunner gland adenomas are hyperplastic areas of the Brunner glands within the duodenum that are greater than 1 cm. Duodenal carcinoma originating in Brunner’s gland is rare. A rare case of Brunner’s gland hyperplasia mimicking duodenal cancer is reported. Where the focal growth of hyperplastic cells is greater than 1 cm in diameter, the hyperplastic region is referred to as Brunner gland adenoma. Hence, we decided to perform partial duodenectomy to reduce operative stress. Am J Surg 1961;101:253. of Surgery L, University Hospital of Aarhus, Kommunehospitalet, Denmark. 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 hamartomas are mostly located in the duodenal bulb [57%]. Benign prostatic hyperplasia(BPH) / Nodular hyperplasia of prostate. Although the cause of Brunner’s gland hamartomas is unknown, interesting associations have been noted. The interface between normal small intestine and the polyp was visible. Patients may harbour the lesion for long periods with little symptoms and upon treatment have good outcomes.
