A case of granular cell myoblastoma of the bronchus is added to the 42 already reported in the English literature. The extensive spread of the tumor along the bronchus is an unusual feature. A 12-year followup on a case previously reported demonstrates cure following adequate resection. From a review of the literature we concluded that this tumor is found most often in the fourth and fifth decade of life, has equal sex incidence and generalized distribution throughout the bronchial tree. The best results follow lung-saving procedures such as bronchotomy, wedge or sleeve resection of the involved bronchus.
