To the 44 observations of endobronchial granular cell myoblastoma described in the world literature can be added the case of a 52-year-old patient who presented with bifocal localization of this rare tumor of enigmatic origin. The two tumors were isolated from each other, one being situated at the level of the bronchus of the left superior lobe without implantation on the main bronchus, and the other at the bifurcation of the anterior segmental bronchus and left apico-dorsal segmental bronchus. The irreversible chronic-inflammatory peripheral lesions necessitated pneumonectomy. The patient is in excellent health 17 years after pneumonectomy. This is the fifth case of bifocal bronchial granular cell myoblastoma to be published.
