Wegener's granulomatosis: an unusual cause of upper airway obstruction.

A 10-year-old child with a 2-month history of tracheitis presented with acute stridor, for which he required tracheostomy. Granulation tissue was found in the subglottic region and he was treated with antibiotics and corticosteroids. A week after successful decannulation of his tracheostomy, his stridor recurred and, on endoscopy under general anaesthesia, circumferential granulomas extending into both main bronchi were found. A diagnosis of Wegener's granulomatosis was made and confirmed on histology.
