title: Endotracheal granular cell myoblastoma. A failure of laser therapy.
abstract: A patient had multicentric endobronchial granular cell myoblastoma. Progression with worsening tracheal obstruction following carbon dioxide laser therapy led to surgical resection. Flow volume loops documented progressive relief of airway obstruction after laser and resectional surgery. Our experience with failure of laser therapy supports previous recommendations for surgical therapy for large (greater than 8 mm) lesions of the trachea.
