Abstract

Neurilemmomas are relatively uncommon, slowly growing tumors which originate from Schwann cells. Intrathoracic neurilemmomas often occur in the chest wall and posterior mediastinum, but endobronchial neurilemmomas are exceedingly rare. These tumors in trachea or bronchus are usually detected by radiologic examinations, mostly computed tomography scan of chest. An 88-year-old man was admitted for management of pneumonia in left lower lobe and parapneumonic effusion. On bronchoscopic examination, there was a small polypoid nodule less than 1 cm in diameter mimicking an endobronchial inflammatory polyp at the bifurcation of the right anterior segmental bronchus and lateral segmental bronchus and under auto-fluorescence imaging, the nodule showed reddish brown area with defined margin. The bronchoscopic biopsy revealed that the bronchial nodule was endobronchial neurilemmoma. This is an interesting case of endobronchial neurilemmoma mimicking a bronchial polyp that is detected incidentally via bronchoscopy.
