Spontaneous resolution of an intratracheal mass: report of one case

Abstract:
A 14 year-old boy was investigated for a slowly resolving right upper lobe consolidation persisting for 3 months after a pneumonic episode. A flexible bronchoscopy showed a polypoid mass in the carina with extension to the right proximal bronchus. The bronchial washings study for fungus, acid-fast bacilli and polymerase chain reaction for mycobacterium were negative. A reported bronchoscopic examination 8 months later revealed no tracheal mass or subsequent stenosis. A tracheal mass in an asymptomatic and non-progressive child may be managed alternatively by repeated bronchoscopic examinations at intervals instead of immediate bronchoscopic excision or thoracotomy.
