Abstract
Intratumoral injection of ethanol via a flexible bronchofiberscopy was performed effectively in a 64-year-old woman with obstruction of the left lower lobe bronchus caused by endobronchial hamartoma. She was admitted with a history of dyspneic sensation continuing for one month. Bronchofiberscopy revealed a endobronchial tumor obstructing the left lower lobe trunchus. Repeated biopsies showed no malignancy, but not definitive diagnosis was obtained. The obstruction was improved by several bronchofiberscopic intratumoral injections of ethanol, and the tumor was proved to originate from B^6. Left S^6 segmentectomy was performed with intraoperative diagnosis of chondromatous hamartoma. Intratumoral injection of ethanol is considered to be a promising endoscopic treatment to eliminate or reduse obstruction caused by endobronchial hamartoma.
