原发于气管之肿瘤极为少见,常被延误诊断。据报告之21例(恶性15例,良性6例)资料分析,被延误诊断的时间平均是10个月。本文结合病例重点讨论提高早期诊断水平问题。归纳有如下数点:(1)哮喘是气管肿瘤的主要和常见症状(占57％),其次是咯血、咳嗽、气短(各占33％)。初诊时常被误诊而按哮喘病、慢性支气管炎或心脏疾患给予较长时期的治疗。作者因此提出,凡成人发生哮喘或有上述其它症状接受药物治疗而不奏效者,均应对气管、支气管进行全面的检查。并建议在哮喘的鉴别诊断中包括气管肿瘤。
Primary tumors in the trachea are extremely rare and are often delayed in diagnosis. According to the reported data of 21 cases (15 cases of malignant and 6 cases of benign), the average time for diagnosis was 10 months. This article focuses on discussing cases to improve the level of early diagnosis. Summarized the following points: (1) asthma is the main and common symptoms of tracheal tumor (57%), followed by hemoptysis, cough, shortness of breath (each 33%). Initial diagnosis is often misdiagnosed according to asthma, chronic bronchitis or heart disease given longer treatment. Therefore, the authors suggest that tracheal and bronchial examinations should be thoroughly examined in all adults with asthma or other medical conditions other than those prescribed above. It is also recommended to include tracheal tumors in the differential diagnosis of asthma.
