[Duodenal lipoma is a rare cause of gastrointestinal bleeding]

Lipomas of the gastrointestinal tract are extremely rare, slow-growing and most often asymptomatic tumours. They are composed of highly differentiated fat cells surrounded by a fibrous capsule. Tumours larger than 2 cm can produce symptoms of abdominal pain and discomfort or cause anaemia due to ulceration and bleeding, or intestinal obstruction due to intussusception. This is a case report of a 73-year-old man with a bleeding duodenal lipoma situated at the papilla duodeni major which caused difficulty in the diagnostic process, and the endoscopic visualization raised suspicion of cancer of the papilla.
