Granular cell myoblastoma of the bronchus. Case report and literature review

A case of multiple granular cell myoblastomas of the tracheobronchial tree is presented. The patient is well 32 months following endobronchial removal. Only 46 cases of solitary and two cases of multiple lesions of the tracheobronchial tree have been described in the literature. These lesions occur with equal frequency in men and women; at a median age of 38 years; more requently on the right than on the left; and most commonly with cough as the presenting symptom. Most patients have been treated with major surgical resections, but conservative endobronchial removal may be effective therapy.
