Mucoepidermoid carcinoma (MEC) of the tracheobronchial tree represents 0.2% of all lung tumours. It arises from the excretory ducts of the bronchial mucosa and is classified into low- and high-grade tumours using criteria derived from similar tumours of the major salivary glands. Low-grade MEC behaves in a benign fashion with less parenchymal and hilar lymph nodal invasion. The traditional method of treatment is by thoracotomy. The bronchoscopic approach to this lesion using lasers has rarely been reported. This article reports two cases of low-grade tracheobronchial MEC, which were both managed through bronchoscopic neodymium yttrium aluminium garnet (Nd-YAG) laser surgery. The patients were free from disease, 26 and 36 months after surgery. Bronchoscopic laser surgery promises to be an effective alternative treatment modality for tracheobronchial MEC. It is minimally invasive, results in less hospital stay and does not impair pulmonary functions.
气管支气管树的黏液表皮样癌（MEC）占所有肺部肿瘤的0.2%。它起源于支气管黏膜的排泄管，并根据源自大唾液腺类似肿瘤的标准分为低级别和高级别肿瘤。低级别MEC表现为良性，实质和肺门淋巴结侵犯较少。传统的治疗方法是开胸手术。使用激光治疗该病变的支气管镜方法鲜有报道。本文报告了两例低级别气管支气管MEC病例，均通过支气管镜钕钇铝石榴石（Nd-YAG）激光手术进行治疗。术后26个月和36个月时，患者均无疾病。支气管镜激光手术有望成为气管支气管MEC的一种有效替代治疗方式。它微创，住院时间短，且不损害肺功能。
