Most tracheal tumors are malignant, and benign neoplasms are extremely rare. We herein report the case of a 60-year-old woman with a tracheal lipoma obstructing the right main bronchus in whom a preoperative diagnosis was not able to be established. Thus, a thoracotomy was performed followed by complete resection of the tumor including two rings of the tracheal wall. Pathologic examination confirmed that the tumor was a lipoma covered with tracheal epithelium, extending between the cartilage into the outer layer of the trachea.
大多数气管肿瘤是恶性的，良性肿瘤极为罕见。我们在此报告一例60岁女性患者，其气管脂肪瘤阻塞右主支气管，术前未能明确诊断。因此，进行了开胸手术，随后完整切除肿瘤，包括气管壁的两个环。病理检查证实肿瘤是一个覆盖气管上皮的脂肪瘤，在软骨之间延伸至气管外层。
