Brunner gland hyperplasia of duodenum: A rare case mimicking malignancy with obstruction

Abstract

An extremely uncommon benign tumor of duodenum, Brunner gland hyperplasia (BGH), is hereby reported in a 51-year-old male, who presented with recurrent vomiting and epigastric discomfort. Upper gastrointestinal endoscopy, computed tomography scan abdomen, and clinical presentation were suspicious of a malignant tumor with gastric outlet obstructive symptoms, and hence, pancreaticoduodenectomy was done. Post-operative histopathological examination confirmed it to be BGH.
