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.
脂肪肉瘤是最常见的恶性软组织肿瘤，主要见于四肢和腹膜后，但发生于腹腔脏器者罕见。其中大多数病例报道于食管和胃。在胃肠道脂肪肉瘤中，原发性十二指肠脂肪肉瘤极为罕见，文献中仅有5例记录。我们描述了一例66岁女性，表现为晕厥、黑便和贫血。计算机断层扫描（CT）显示十二指肠上壁软组织肿块及肝脏低密度强化肿块。行内镜检查，发现十二指肠肿块导致胃出口梗阻并大量出血。因此，行剖腹手术，广泛松解粘连并行胃空肠吻合术。
