title: [Double-primary cancer of the lung and trachea].
abstract: A 70-year-old woman with no history of smoking was admitted to the hospital because of a persistent cough and pneumonia in the right lower lobe. Examination with a fiberoptic bronchoscope revealed an intratracheal polypoid tumor and a polypoid tumor almost completely obstructing the right bronchus B(8). Biopsies were done, and histological diagnosis of both tumors was squamous cell carcinoma. A sleeve resection of the trachea with end-to-end anastomosis and right lower lobectomy were done. Examination of specimens resected from both tumors revealed moderately differentiated squamous cell carcinoma. Synchronous double-primary cancer (both squamous cell carcinoma) of the lung and trachea in a non-smoker is very rare.
