A 17-year-old girl was referred to our hospital with atelectasis of left lung due to tumor occlusion. Clearance of the tumor was performed by mechanical removal and application of Nd-YAG laser or electrocautery. The histopathological diagnosis was typical carcinoid. Chest computed tomography showed extraluminal residual lesions. Left upper lung sleeve lobectomy was performed 1 year after initial treatment. Interestingly, the histology of the resected specimen showed that the tumor cells exist only on the outer side of the bronchial cartilage and not in the bronchial luminal surface, suggesting the effectiveness of the initial bronchoscopic treatment.
