Brunner’s gland hyperplasia: A rare cause of gastrointestinal bleeding

Brunner’s gland hyperplasia (BGH) is an unusual entity that presents with large duodenal polyp or mass and rarely causes gastrointestinal bleeding. It is usually asymptomatic and often an incidental finding during the esophagoduodenoscopy (EGD). However, most of the cases are benign. We encounter a 40 years old man who presented in Emergency Room with melena. EGD revealed solitary, large duodenal polyp in second part of duodenum and later histopathological findings were consistent with BGH.
