Tracheobronchial schwannoma: a case report and literature review.

Primary tracheobronchial schwannoma is extremely rare. A woman in her early 60 s was admitted to our department with a 2-month history of cough and expectoration. Chest computed tomography (CT) revealed a high-density nodule at the opening of the right main bronchus, accompanied by atelectasis in the middle and lower lobes.
