Dyspnea was the only significant clinical symptom in a patient suffering from a primary tracheal tumor. Tracheography and tracheal tomography revealed a marked stenosis in the medium third of this organ. The endoscopic biopsy identified a squamous carcinoma. Medical treatment and radiation gave only temporary tumor control. The uncommoness of primary tracheal neoplasms, one per each 180 cases of lung tumor, is stressed. The diagnosis is usually made in advanced stages due to the lack of initial symptoms and because these patients are frequently catalogued as asthmatics or bronchitics. Performance of flow-volume loops using a mixture of helium and oxygen increases the diagnostic percentages, since it is possible to separate those cases with diffuse airway obstruction.
呼吸困难是一名原发性气管肿瘤患者唯一显著的临床症状。气管造影和气管断层扫描显示该器官中三分之一处有明显狭窄。内镜活检确诊为鳞状细胞癌。药物治疗和放疗仅能使肿瘤得到暂时控制。文中强调了原发性气管肿瘤的罕见性，每180例肺部肿瘤中才有1例。由于缺乏初始症状，且这些患者常被归类为哮喘或支气管炎患者，所以诊断通常在晚期进行。使用氦氧混合气体进行流量-容积环检查可提高诊断率，因为这样有可能区分出弥漫性气道阻塞的病例。
