title: A case of intratracheal schwannoma presenting at the emergency department with a diagnosis of asthmatic attack.
abstract: Primary tumors of the tracheobronchial tree are rare, and benign tumors are even rarer. Patients with tracheobronchial tumors are at times wrongly diagnosed with asthma. A 77-year-old woman presented to our Emergency Department with increasing dyspnea and stridor. She had been treated for bronchial asthma for the last 7 years. Due to the presence of the stridor, a cervical soft tissue computed tomography scan was performed. It revealed a tracheal polyp at the level of the thyroidal isthmus. Polyp excision with rigid bronchoscopy was performed by a thoracic surgeon. This case demonstrates that intratracheal masses should be considered in patients with dyspnea and stridor or in patients with asthma refractory to usual treatment.
