A solitary, benign, keratinizing, squamous cell papilloma was found in the lingula of a 74-year-old-man. The patient had been a heavy smoker for many years and gave a history of chest pain, weight loss, night sweats, and a productive cough with streaking hemoptysis. A Salmonella typhimurium abscess was found distal to the tumor. Lobectomy was performed. There has been no evidence of recurrence in a 3-year follow-up. The world literature since 1892 contains five previous reports of solitary squamous cell papillomas of tracheobronchial origin.
