Tracheal adenoid cystic carcinoma masquerading asthma: a case report
Nurdan Kokturk et al. BMC Pulm Med. 2004.
Abstract
Background: Tracheal tumors are often misdiagnosed as asthma and are treated with inhaled steroids and bronchodilators without resolution.
Case presentation: Here, a patient with tracheal adenoid cystic carcinoma who had been previously diagnosed with difficult asthma was reported. The possibility of the presence of localized airway obstruction was raised when the flow-volume curve suggesting fixed airway obstruction, was obtained.
Conclusion: The presenting case report emphasizes the fact that not all wheezes are asthma. It is critical to bear in mind that if a patient does not respond to appropriate anti-asthma therapy, localized obstructions should be ruled out before establishing the diagnosis of asthma.
