RESUMEN
Behcet's disease is a recurrent and multisystemic disorder which usually persists over many years. In 1937 Behcet described a chronic relapsing triple symptom complex of recurrent oral ulceration, genital ulceration and ocular inflammation. Other manifestations of the syndrome include arthritis, cutaneous vasculitis, thrombophlebitis, epididymitis, ulcers of gastrointestinal tract and meningoencephalitis. Recently, a case was experienced involving intestinal Behcet's syndrome with duodenal ulcer bleeding. A 32-year-old male patient was admitted due to hematemesis, and epigastric pain. The patient had ulcers on the oral mucosa, soft palate, external genitalia, and anus. An irregularly marginated ulcer with bleeding was found on the anterior of the duodenal bulb through esophago- gastroduodenoscopic examination. The patient was diagnosed with Behcet's disease and was treated with steroids. In this paper, the case of duodenal bulb involvement of Behcet's disease is reported with a review of relevant literature.
