Primary endobronchial granular cell myoblastoma

Granular cell myoblastoma is a common lesion of uncertain histogenesis. It
commonly affects the tongue, breast, and subcutaneous tissues. However, its
occurrence in the tracheobronchial tree is rare. Although generally a
benign lesion, isolated malignant granular cell myoblastoma as well as its
coexistence with other primary bronchogenic carcinomas has been documented.
In spite of recent anecdotal reports advocating endoscopic removal of this
lesion, we believe definitive surgical excision is a more rational choice
of treatment.
