RT Journal Article SR Electronic T1 Solitary Primary Tracheal Small-Cell Lung Cancer Causing Acute Respiratory Failure: Diagnosis and Treatment JF Respiratory Care FD American Association for Respiratory Care SP 929 OP 932 VO 55 IS 7 A1 Lan, Chou-Chin A1 Yang, Mei-Chen A1 Lee, Chih-Hsin A1 Huang, Shiu-Feng A1 Wu, Yao-Kuang YR 2010 UL http://rc.rcjournal.com/content/55/7/929.abstract AB Small-cell lung cancer often presents as an extensive cancer, and rarely as a solitary tracheal tumor. We report a 41-year-old male smoker with dyspnea and wheezing that was initially diagnosed as asthma and treated with bronchodilators. He was later intubated for acute respiratory failure, and computed tomography revealed a tracheal mass. Solitary primary small-cell lung cancer was diagnosed via bronchoscopic biopsy. The patient received bronchoscopic electro-surgery and was successfully extubated. Concurrent chemo-radiotherapy was performed due to the stage IV small-cell lung cancer.
