This is a report of pulmonary squamous cell carcinoma that developed around a bullet lodged in the lung for 47 years.<BR>A 67-year-old man was admitted to our hospital complaining of hemosputum. He was shot in the right thorax during World War II and the bullet had lodged in his right lung. Chest X-rays showed a bullet in the right upper lobe with a tumor shadow around it. Pulmonary squamous cell carcinama was diagnosed by bronchoscopic biopsy. Lobectomy was performed after irradiation and chemotherapy.<BR>Three lesions were found in contact with each other in the resected lobe : a bullet surrounded by fibrous tissue, tuberculosis and squamous cell carcinoma. Since these three lesions had been strongly affected by irradiation, a direct connection between the bullet and the carcinoma could not be proved microscopically. However, it can be considered that the bullet was responsible for the etiology of the carcinoma, as well as the tuberculosis.
