Microscopic examination of the nonadenomatous polyps (n=27) led to a variety of findings duodenitis/inflammatory polyp (n=10), normal duodenal tissue (n=7), gastric heterotopia (n=4), Brunner's gland hyperplasia (n=2), hyperplastic polyp (n=1), leiomyoma (n=1), lipoma (n=1), and vascular ectasia consistent with portal hypertensive duodenopathy (n=1).
Brunner's gland adenomas are largely benign tumours located predominately in the first part of the duodenum.
We recently encountered a patient with a sessile polyp in the second portion of the duodenum that was successfully resected by endoscopic mucosal resection and diagnosed as adenocarcinoma in situ arising from the Brunner's gland. In this report, we focus mainly on the pathological characteristics of the adenocarcinoma and review previously reported cases of this disease.
To our knowledge, never before has a Brunner's gland hamartoma been described presenting with such severe anemia and this size, requiring blood transfusions and a Whipple procedure.

Canine Brunner's glands are rich, and the unit cavity that secretes mucus is large and lined with tall columnar cells; feline villi are long, and rich Brunner's glands enter the muscularis mucosa and divide into many independent lobules; equine Brunner's glands are both mucoid and serous, but the secretory cavity is very small; the porcine duodenal gland also extends a significant length in the jejunum (Huang, 1990; William and Chen, 2007; Wang, 2002).
