Upper gastrointestinal bleeding as an unusual presentation of a duodenal carcinoid.
Carcinoid tumors may develop in any part of the gastrointestinal tract. They constitute 1.5% of all gastrointestinal tumors (1). The duodenum is one of the least common sites of this tumor, with a reported incidence varying between 0.2% and 8.9% (2, 3). We report on a case of a bleeding duodenal carcinoid in a patient who underwent bilateral nephrectomy for malignant hypertension.
