Abstract
- Brunner's gland hyperplasia, also known as Brunner's gland adenoma or hamartoma, is often encountered as a proliferative lesion arising from the Brunner's glands of the duodenum. This lesion has previously been described as being benign, with no malignant potential. We report a case of Brunner's gland hyperplasia that was incidentally discovered on endoscopy for evaluation of gastrointestinal bleeding. The histopathological findings of this lesion revealed a marked dysplastic and malignant changes from the normal Brunner's gland structure. Our case demonstrates the possibility of malignant potential in the natural history of Brunner's gland hyperplasia, even though its incidence is very rare.
