Brunner's gland hamartoma with dysplasia, presenting as multiple duodenal polyps: An unexplored entity with literature review

Brunner's gland hamartomas (BGHs) are uncommon lesions of duodenum which show hyperplasia of these glands along with smooth muscle bundles, adipose tissue and lymphoid aggregates. These are usually benign, solitary, pedunculated, polypoidal lesions. Dysplastic changes in BGH are extremely rare and even rarer is the multiplicity of this lesion. We hereby report an index case of BGH showing features of high-grade dysplasia, presenting as multiple duodenal polyps.
