Multiple granular cell tumors of the bronchi: treatment with laser.

Abstract

Granular cell tumors involving multiple bronchial and extrapulmonary sites were found in a young man. Carbon dioxide laser ray was applied through a specially fitted rigid bronchoscope to a lesion at the left mainstem bronchus. Serial follow-up bronchoscopies revealed a white scarred plaque without evidence of regrowth. A partially obstructing lesion at the left lower lobe bronchus did not respond to one application of laser therapy. Laser treatment of proximal benign bronchial lesions is feasible; however, peripheral lesions may require several courses of laser therapy.
