Résumé
Brunners gland adenoma is a benign epithelial tumor of the duodenum originating from submucosal Brunners gland. This is an extremely rare entity that account for only 10.6% of benign duodenal tumor, which are themselves relatively rare, representing 0.008% of all surgical and autopsy specimens. The clinical manifestation are nonspecific gastrointestinal complaints, such as bloating or epigastric pain, and the tumor gives rise to melena or anemia, due to the ulceration or erosion of the tumor. The diagnosis is usually made by radiologic studies and gastroduodenal endoscopy which can also provide definitive treatment. The aim of treatment is complete removal of the lesion and exclude malignancy. We report on 4 cases of Brunners gland adenoma which was confirmed by operation or endoscopic polypectomy.
