A 64-year-old male, who had received successful radiotherapy for the previous laryngeal cancer, was admitted to our department for the treatment of a peripheral pulmonary tumor in the right upper lobe and an endotracheal tumor in the carina. The endotracheal biopsy of the carinal tumor demonstrated squamous cell carcinoma, though preoperative examination of the intrapulmonary tumor was unable to clarify it's pathological type. The intrapulmonary tumor required right upper lobectomy and R2 lymph node dissection as a measure against the possibility of primary lung cancer. Since the endotracheal cancer was diagnosed as an intra mucosal tumor by the preoperative computed tomography (CT) scans and the bronchoscopic examination, laser abrasion therapy to the endotracheal tumor was performed 4 days before the lobectomy of the intrapulmonary tumor. After the pulmonary operation, the intrapulmonary tumor was diagnosed as squamous cell carcinoma without lymph node metastasis, and it was suggested to be a metastatic tumor of the previous laryngeal cancer. Both radiotherapy to the carina and general chemotherapy with docetaxel hydrate and carboplatin were used as adjuvant therapies 36 days after the lobectomy. One year after the pulmonary surgery, there is no recurrence of the tumor in the lung or carina. Laser abrasion therapy to the endotracheal tumor is very useful and safe for the patient, who should then receive pulmonary resection soon after the therapy.
