Core Tip

Core Tip: Brunner’s gland hyperplasia (BGH) and lipomatous pseudohypertrophy (LiPH) of the pancreas are rare diseases. We present a case with coexisting LiPH of the pancreas and a huge pedunculated BGH of the duodenum that presented with upper gastrointestinal bleeding. Esophagogastroduodenoscopy revealed a large submucosal mass along the duodenum with central ulceration, and radiological examination showed marked thickening of the duodenal walls and fatty replacement over the entire pancreatic parenchyma. Diagnoses of BGH and LiPH were confirmed by histological evaluations. Although rare, BGH can cause gastrointestinal bleeding. Furthermore, this case highlights the usefulness of combined esophagogastroduodenoscopy and radiological examinations in patients with melena.
