title: Obstructing tracheobronchial schwannoma.
abstract: Endotracheal and endobronchial schwannomas are extremely rare tumors of neurogenic origin. These tumors often present late. Common symptoms of hemoptysis and dyspnea result from the size and location of the tumors. Two cases of tracheobronchial schwannoma with proximal airway obstruction are reported. Various diagnostic modalities employed in the evaluation of these tumors are reviewed. Because malignant transformation is exceedingly rare, operative resection of tracheobronchial schwannomas based on the principle of conservation of lung parenchyma is emphasized.
