Two cases of Endobronchial Neurilemmoma and Review of the Literature in Korea / 결핵및호흡기질환

ABSTRACT

Neurilemmomas are benign tumors that originate from Schwann cells. These tumors rarely occur in the trachea or bronchus. Although small peripheral lesions cause no symptoms, they usually cause dyspnea, cough, wheeze, and atelectasis. We encountered two cases of endobronchial neurilemmoma, and reviewed 10 cases previously reported in Korea in order to clarify the characteristics of this disease, and to determine the appropriate treatment. The median age of the 12 patients reviewed were 36.5 (range 16-75). Cough and dyspnea were the most common initial symptoms (40%), and two cases had no symptoms. Regarding the diagnostic methods, bronchoscopic biopsy was found to be inadequate for diagnosis in two cases. A review of the cases revealed the following teatments: bronchoscopic removal in two cases, surgery in six cases, and combined bronchoscopic removal and surgery in one case.
