硬性気管支鏡下切除後に気管支楔状切除を伴う右肺上葉切除で完全切除した中枢型気管支カルチノイドの1例

Bronchial Typical Carcinoid Tumor Treated with Two-stage Resection；Report of a Case

はじめに　気管支カルチノイドは低悪性度の腫瘍であり，原発性肺癌の中では約1～5％とされる比較的まれな腫瘍である．われわれは末梢肺の無気肺を伴った中枢発生の定型気管支カルチノイドに対して，二期的に完全切除を行った症例を経験したので報告する．

A 45-year-old woman, who had been treated for bronchial asthma, was referred to our hospital with symptoms of dyspnea. Upon examination, we found the right main bronchus to be almost completely occluded by an endobronchial tumor. For the purpose of diagnosis and relieving the dyspnea, we performed a rigid bronchoscopic tumor resection with a high frequency snare. The tumor was pathologically diagnosed as a typical bronchial carcinoid, and a right upper lobectomy and wedge resection of the right main bronchus was carried out 1 month later.
