Leiomyosarcoma of duodenum is a rare malignant tumor, only ten percent are found in the duo- denum. The most common symptotns are abdominal pain, melena, weakness, weight loss, and jaundice, fever are rare complants. We reported a case of leiomyosarcoma with abscess formation in 54 year-old man confirmed by exploration and excisional biopsy. His chief complaints were right upper quadrant pain and high fever, a mass lesion combined with air bubbles on computerized tomography, upper gastrointestinal findings showed a duodenal mass hanging on 2nd and 3rd portion of duodenum and mucosal destruction. Excisional biopsy revealed low grade leiomyosar- coma in duodenum combined with necrosis and suppurations. (Korean J Gastroenterol 1996;28: 566 - 570)
