title: [Brunner's gland adenoma: a rare tumor as cause of pyloric syndrome in an AIDS patient].
abstract: Brunner's gland adenoma is a rare neoplasm that accounts for only the 0.008% of all benign duodenal tumors. Here we describe the case ofan HIV-seropositive man who developed a severe pyloric stenosis due to a Brunner's adenoma of the bulb and the first duodenal portion. Gastroduodenoscopy showed a large polypoid tumor that obstructed the pyloric region. The lesion was resected by surgery and a gastroduodenal anastomosis was made. The histopathologic examination of the surgical specimen showed a large proliferation of Brunner's glands into a large pedunculated polyp that confirmed the diagnosis of this hamartoma.
