気管支鏡インターベンション後に左上葉スリーブ切除を要した気管支原発定型カルチノイド

Bronchial Typical Carcinoid Requiring Left Upper Sleeve Lobectomy after Rigid Bronchoscopic Intervention

肺・気管支カルチノイドは，全肺腫瘍の1％と比較的まれな低悪性度の腫瘍として扱われている．われわれは，治療に苦慮した若年発生の定型カルチノイド（TC）例を経験したので報告する．

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.
