An unusual case of bronchial adenoma in childhood.

A 26-year-old woman harbored a symptomatic mucoepidermoid bronchial adenoma for 24 years, confirmed by a bronchoscopic biopsy examination 18 years before surgical therapy. The snug incarceration of the bulbous tip of the long, pedunculated tumor by the margins of the left upper lobe bronchial orifice led us to conclude in error that the tumor originated within the left main stem bronchus at the point of juncture between left upper lobe and main stem bronchi; and therefore to undertake needlessly extensive resection. A more extensive bronchotomy could have revealed the unique growth pattern of the lesion.
