RESUMO
The Brunner's gland adenoma is characterized by a nodular proliferation of histologically normal Brunner's gland, accompanied by ducts and scattered stromal elements. First descrived by Salvioli in 1876, the tumor is relatively rare, with 119 cases reported by 1977, The most common benign tumor of the small bowel is the adenoma, 25% of which occur in the duodenum. They make up 30% to 50% of all hyperplastic polyps of the duodenum. Most frequently these tumors are discovered in patients in the fourth to sixed decades of life, though the age in reported caes ranges from l 1 days to 80 years. The benign tumors of the duodenum 30% to 50% contain elements of Brunner's gland and 10.6% of them are adenomas of Brunner's gland. We report a case of Brunner's gland adenoma treated by endoscopic polypectomy in 63 year-old woman, and reviewed the literatues of adenoma of the Brunne'r gland.
