title: Duodenal Lipoma as a Rare Cause of Upper Gastrointestinal Bleeding.
abstract: A 52-year-old female was referred because of melaena. After initital work-up, including gastroduodenoscopy, endosonography and CT scan, a duodenotomy was performed. Definite diagnosis was a duodenal lipoma based on histological findings. Lipomas of the gastrointestinal tract are rare. Only 4% occur in the duodenum. The peak incidence is around the 5th and 7th decade of life, with a slight female preponderance. Gastrointestinal lipomas are usually asymptomatic, but can present with mild to severe gastrointestinal bleeding, intussusceptions, abdominal pain, constipation and diarrhea. Clinical, endoscopical, surgical, and radiological features are described in this case of duodenal lipoma.
