7例原发性气管恶性肿瘤与支气管哮喘的鉴别诊断

A report of 7 cases of tracheal cancer and its differential diagnosis from bronchial asthma

目的 了解气管肿瘤与支气管哮喘的鉴别。方法 对 7例误诊为哮喘的气管肿瘤患者的临床表现和相关检查进行分析。结果 7例患者误诊时间平均 5个月。与支气管哮喘的不同点有 :( 1)呼吸困难以吸气时明显 ,哮鸣音多不典型 ,以上肺部和喉部为最响。 ( 2 )病人以喉部痰多 ,喉部多闻及痰鸣音。 ( 3)咳喘随着病程的延长而逐渐加重。结论 及早对可疑病人行纤维支气管镜检查可明确诊断。

Objective To report 7 cases of primary tracheal carcinoma and study its differential diagnosis from bronchial asthma. Methods 7 cases of primary tracheal cancer and their clinical manifestations were reviewed and analyzed, and the differential diagnosis was discussed. Results Primary tracheal cancers were rarely seen and easily miss diagnosed. The average miss diagnosis time was 5 months. Here the clinical manifestations of these tumors were studied in details. The main differences of tracheal cancer to bronchial asthma were 1. Dyspnea was more apparent in aspiration in tracheal tumors; 2. Spuctum was plentiful and bronchial wheeze were frequently heard; 3. Clinical symptoms became more and more apparent as time went on. Conclusion Primary tracheal cancers are easily misdiagnosed and confused with bronchial asthma. Hence, the differential diagnosis between the two should be careful.
