Primary dedifferentiated liposarcoma originating in the mediastinum is extremely uncommon. Here, we report a case of mediastinal dedifferentiated liposarcoma. A 74-year-old man was admitted to our hospital with a left intrathoracic tumor ∼10 cm in diameter. Computed tomography that was taken in another hospital 2 years before the initial visit to our hospital had shown a lipomatous tumor ∼3 cm in diameter adjacent to the left lower pulmonary vein. The tumor was resected by left lateral thoracotomy with video-assisted thoracoscopic surgery. Pathological examination revealed primary mediastinal dedifferentiated liposarcoma. No evidence of recurrence has been seen as of 8 months postoperatively.

起源于纵隔的原发性去分化脂肪肉瘤极为罕见。在此，我们报告一例纵隔去分化脂肪肉瘤病例。一名74岁男性因左胸内直径约10 cm的肿瘤入住我院。在初次就诊我院的2年前，另一家医院进行的计算机断层扫描显示，左肺下静脉旁有一个直径约3 cm的脂肪瘤样肿瘤。通过左侧开胸电视辅助胸腔镜手术切除了该肿瘤。病理检查显示为原发性纵隔去分化脂肪肉瘤。术后8个月未见复发迹象。
