Use of Nd:YAG laser in endobronchial granular cell myoblastoma.

Granular cell myoblastoma is an uncommon benign tumor that causes pulmonary complications due to obstruction of the airways. We report the first case of bronchial obstruction due to granular cell tumor treated with Nd:YAG laser. The Nd:YAG laser appears to be an effective new tool for relieving obstruction and, in some cases, preventing recurrence, and can be delivered with the use of a flexible bronchoscope.
