A 7-year-old black boy presented to the Pediatric Pulmonology Service with a 2-year history of progressive dyspnea on exertion and nocturnal wheezing. He was thought to have asthma, although the findings of pulmonary function tests were normal. A chest x-ray film was not obtained. The patient was treated with bronchodilator therapy, without significant improvement in his symptoms. Over the following 2 months, he developed increasing stridor. Because of progression of his symptoms, flexible bronchoscopy was performed, revealing a large subglottic mass. During the procedure, the patient developed significant respiratory distress. The Pediatric Otolaryngology Service was urgently consulted for airway management. The patient was taken to the operating room, where a tracheostomy was performed, followed by laryngoscopy and bronchoscopy. The vocal cords were normal. A subglottic mass was found to obstruct approximately 90% of the airway lumen (Figure 1). Biopsy specimens were obtained of the submucosal lesion, which was noted
