Complications during removal of a pedunculated endobronchial leiomyosarcoma.

Pedunculated endobronchial leiomyoma or leiomyosarcoma is comparatively rare and is known to produce intermittent, partial or complete obstruction of the ipsilateral lung. Rarely it causes obstruction of the contralateral main bronchus. Fatalities have been caused by obstruction of the contralateral main bronchus during surgery. A pedunculated intrabronchial leiomyosarcoma obstructing the contralateral main bronchus is reported.
