[Tracheal Resection and Reconstruction for a Squamous Cell Carcinoma of the Trachea;Report of a Case].

We report a case of tracheal resection and reconstruction for a squamous cell carcinoma of the trachea that was found in an 82-year-old male patient who had underwent right lower lobectomy for an adenosquamous cell carcinoma 3.5 years before. He noticed bloody sputum. Chest computed tomography (CT) revealed a 15 mm tumor in the anterior wall of the trachea. A transbronchial biopsy for the tracheal tumor showed a squamous cell carcinoma. Under right thoracotomy, we resected the tumor with 3 tracheal rings. Histologically a squamous cell carcinoma was diagnozed. As there was intraepithelial spread of cancer cells in the oral margin, the tracheal tumor was suspected to be a primary tracheal tumor rather than a metastasis from lung cancer. After the surgery, combination therapies of an external radiation therapy for 50 Gy and brachytherapy 2 times for totally 8 Gy were performed as a postoperative adjuvant therapy. He does not have any signs of recurrence in 1 year and 6 months after the surgery.
