Primary liposarcoma of the lung is extremely rare. To date, only 24 cases have been reported in the English literature. Herein, we present a case of well-differentiated pulmonary liposarcoma that was misdiagnosed as teratoma on positron emission tomography/computed tomography (CT) and contrast-enhanced CT. Radical surgery with left superior lobectomy and mediastinal lymph node dissection were performed. The patient experienced recurrence and distant metastases 33 months after surgery. He was alive at the time of writing this report (36 months postoperatively). To our knowledge, this is the first case report of pulmonary well-differentiated liposarcoma.
原发性肺脂肪肉瘤极为罕见。迄今为止，英文文献中仅报道了24例。在此，我们报告一例高分化肺脂肪肉瘤病例，该病例在正电子发射断层扫描/计算机断层扫描（CT）及增强CT上被误诊为畸胎瘤。实施了左上肺叶切除术及纵隔淋巴结清扫的根治性手术。患者术后33个月出现复发及远处转移。在撰写本报告时（术后36个月）他仍存活。据我们所知，这是首例高分化肺脂肪肉瘤的病例报告。
