[Melena associated with a Brunner's adenoma]. / Melena op basis van een Brunner-adenoom.

A 68-year-old woman presented at the Casualty Department due to collapse, anaemia, fatigue and progressive dyspnoea. She suffered from melena, indicative of a haemorrhage in the upper gastrointestinal tract. Gastroduodenoscopy revealed the presence of a polyp in the duodenum, which was endoscopically resected. Pathological investigation demonstrated that the polyp was a Brunner's adenoma, i.e. a circumscript benign submucosal nodular hyperplasia of the Brunner's glands.
