Lung teratoma is a rare disease to date. About 43 cases have been described in the literature. We report on a 28-year-old man who presented fever, cough and hemoptysis for four months. Chest X-ray and computerized tomography showed opacification of the left upper lobe and bronchoscopy revealed the presence of hair at the site. The patient's condition improved with surgical treatment.
