title: Adult idiopathic subglottic stenosis: a diagnostic and therapeutic challenge.
abstract: A 22-year-old woman presented with effort dyspnea unresponsive to bronchodilators. Harsh respiratory sounds were audible at the neck. Thoracic and cardiac evaluation was normal. Spirometry revealed an obstructive ventilatory defect, and the flow-volume loop indicated upper airway obstruction. Bronchoscopy and tracheal computed tomography revealed a stenosis of the subglottic larynx. A biopsy specimen of the stenotic area of the trachea showed a normal mucosa and non-specific chronic inflammation. The tracheal stenosis was managed by means of endobronchial laser therapy, which led to the resolution of the patient's symptoms. As we could not identify any specific pathogenetic process, our final diagnosis was idiopathic subglottic tracheal stenosis.
