A Case of Tracheal Tumor Presented as Bronchial AsthmaA Case of Tracheal Tumor Presented as Bronchial Asthma
Abstract
- Upper airway obstruction is a relatively infrequent cause of obstruction to airflow, but is occuring with increasing frequency as an iatrogenic disease. If recognized, many of the lesions are amenable to corrective surgery. But there is the tendency to overlook obstructing lesion of the major airway in favor of COPD or bronchial asthma in patient with dyspnea and noisy breathing. The flow-volume curve and some data of pulmonary function test indexes (FEF,/FIF 0. etc.) can provide the first clue or the most easily obtained characterization of major airway obstruction, and discrimination between patient with upper airway obstruction and patient with other lung diseases. A 47 year old female patient has been treated as bronchial asthma due to dyspnea of 5 year duration without improvement. The examination for bronchial asthma was negative, but pulmonary function test showed the finding of upper airway obstruction. After further evaluation and tracheal mass escision with tracheostomy, she was diagnosed of adenoid cystic carcinoma of trachea, and is being treated with radiotherapy without dyspnea.
