62歳女.左腎癌摘除術の1年4ヵ月後に生じた右無気肺により気管支内転移(EM)が判明した.肺にも転移が多発しておりEMも多発性であったことから外科的切除の適応はないと考え,EM巣に対してレーザー照射+高周波スネアを施行したA 62-year-old woman, who had undergone left nephrectomy for renal cell carcinoma and had received interferon-alpha for metastasis to the lung, was hospitalized because of cough, dyspnea and anorexia 16 months after nephrectomy. Chest radiography showed collapse of the right lung. We performed bronchoscopy and found a red polypoid tumor completely obstructing the right bronchus. Biopsy specimens showed clear cell carcinoma, similar to previous specimens of renal cell carcinoma. We removed the endobronchial tumor with laser and electrosurgical snaring, after which the right lung reinflated.
