Abstract

Liposarcoma is the most prevalent malignant soft tissue tumor and is primarily found in extremities and retroperitoneum, but its occurrence within abdominal viscera is rare. Most of these cases have been reported in the esophagus and stomach. Among liposarcomas of the gastrointestinal tract, primary duodenal liposarcomas are exceptionally rare, with only five documented cases in the literature. We describe a case of a 66-year-old female presenting with syncope, melena, and anemia. Computed tomography (CT) showed soft tissue mass involving the superior wall of the duodenum and hypo-enhancing hepatic mass. An endoscopy was performed, which revealed a duodenal mass causing gastric outlet obstruction and significant bleeding. Therefore, laparotomy was performed with extensive lysis of adhesions and gastrojejunostomy.
