Pneumothorax as a rare presentation of bronchial schwannoma

Tracheobronchial schwannomas are rare diseases. Common signs and symptoms of this tumor include cough, wheezing, and dyspnea. In contrast, pneumothorax is an exceptional presentation. This study reports the first case of bronchial schwannoma presenting with pneumothorax. A 79-year-old woman was diagnosed with pneumothorax by chest radiography. Chest computed tomography unexpectedly revealed a tumor occluding the right main bronchus. Following the pathological diagnosis of bronchial schwannoma, the patient underwent thoracoscopic tumor enucleation. The airway lumens are consequently secured postoperatively. We reviewed the literature and discussed the mechanisms and treatment options for bronchial benign tumor-associated pneumothorax. Pneumothorax should be aware of a rare presentation of non-malignant tracheobronchial tumors.
