Liposarcomas, the most common soft tissue tumors, occur predominantly in the lower limbs and retroperitoneum. Primary mediastinal liposarcomas are rare and account for <1% of mediastinal masses. We report a case of a large primary mediastinal liposarcoma invading the right ventricular outflow tract, pulmonary artery, and aortic adventitia that was successfully resected. This report highlights the complex nature of liposarcomas, given their tendency to invade critical structures.
脂肪肉瘤是最常见的软组织肿瘤，主要发生于下肢和腹膜后。原发性纵隔脂肪肉瘤罕见，占纵隔肿块的比例不到1%。我们报告一例侵犯右心室流出道、肺动脉和主动脉外膜的巨大原发性纵隔脂肪肉瘤病例，该病例已成功切除。鉴于脂肪肉瘤有侵犯关键结构的倾向，本报告突出了其复杂的性质。
