[A case of bronchial neurinoma]

Neurinoma of the bronchial tree is extremely rare. We report a case of bronchial neurinoma involving a 21-year-old woman. The patient was admitted due to an abnormal shadow on chest X-ray, with cough and sputum production. Chest CT and MRI showed that the tumor arose from the left lower bronchus and bronchofiberscopic examination revealed complete obstruction of the lower bronchus by a polypoid tumor. A left lower lobectomy was performed based on the histological diagnosis of benign neurinoma and the postoperative course was uneventful. The tumor was 7.0 x 6.0 x 5.0 cm in size and had grown endobronchially without penetrating the bronchial wall. Pathological diagnosis was Antoni A type benign neurinoma. Since malignant or metastasized tumors have been reported in cases of tracheobronchial or intrapulmonary neurinoma, complete surgical resection of bronchial neurinomas should be performed.
