The Primary Salivary Gland-type Lung Tumor:Analysis of Diagnosis and Treatment of 12 Cases

目的探讨肺原发唾腺型肿瘤的临床特点,总结其诊治方法。方法对12例肺原发唾腺型肿瘤的临床表现和诊治结果进行回顾性分析。结果12例肺原发唾腺型肿瘤中,腺样囊性癌6例,黏液表皮样癌4例,黏液性腺瘤和混合瘤各1例。患者多表现为咳嗽及痰中带血,偶有胸痛、胸闷、发热,盗汗、消瘦等症状不明显。行肿物单纯切除2例,袖式肺叶切除1例,单纯肺叶切除7例,全肺叶切除2例。结论肺原发唾腺型肿瘤属良性或低度恶性,好发于气管及支气管;主要表现为干咳及痰中带血;X线检查对该病的诊断有一定的局限性,支气管镜检查并活检通常可获得明确诊断;治疗主要为外科手术切除。
