Abstract
|
|
|
Brunner¡¯s gland hyperplasia, also known as Brunner¡¯s gland adenoma, polypoid hamartoma, or Brunneroma, is a rare proliferative lesion arising from the Brunner¡¯s glands of the duodenum. These lesions have been described previously as benign, with no malignant potential. We report a case of Brunner¡¯s gland hyperplasia in the duodenum that was discovered incidentally during the endoscopic evaluation of anal bleeding. Histopathological examination of this Brunner¡¯s gland hyperplasia revealed well-marked, low-grade dysplasia. This case suggests a dysplastic stage with malignant potential in the natural history of Brunner¡¯s gland hyperplasia.
