Abstract

<b>背景.</b>肺多形癌は稀な組織型であり,予後不良とされている.今回我々は,肺多形癌術後の気道内への転移に対して,高周波スネアによる気管支鏡下切除を繰り返し行った症例を経験したので報告する.<b>症例.</b>69歳,男性.肺多形癌に対して右下葉切除を行った2年後に呼吸困難,喘鳴を自覚し,救急受診した.画像検査により,気管内に突出する腫瘍を指摘された.気管支鏡下に高周波スネアによる切除を行った.その後,10,12か月後にも気道内への再発を認めたが,いずれも同様に高周波スネアにより気管支鏡的切除を行い,気道確保に成功した.大出血などの合併症はみられなかった.<b>結論.</b>気道内への腫瘍に対しての高周波スネアを用いた気管支鏡下切除は,有効かつ安全に,繰り返し行うことが可能である.

<b><i>Background. </i></b>Pulmonary pleomorphic carcinoma is a rare sarcomatoid carcinoma known to be refractory to treatment. <b><i>Case. </i></b>A 69-year-old male was admitted with severe dyspnea and stridor exhibiting sudden onset. He had undergone right lower lobectomy for pulmonary pleomorphic carcinoma two years previously. Chest computed tomography performed on the current admission revealed a tracheal tumor, and we removed the mass with a high-frequency electrosurgical snare. A pathological examination showed metastasis of the pulmonary pleomorphic carcinoma, and radiation therapy was added. However, the tumor relapsed 10 and 12 months after the first bronchoscopic resection procedure, and endoscopic resection was repeated. <b><i>Conclusions. </i></b>Endoscopic electrosurgery with a high-frequency snare is safe and useful for tracheobronchial tumors.
