We describe the case of a 36-year-old man who presented with chest pain and a mass lesion occupying 2/3rds of the left hemithorax on a chest radiograph. A malignant pulmonary tumor was suspected, and after all diagnostic procedures, spindle-cell carcinoma was considered. Because of the proximity of the lesion to vascular structures, chemoradiotherapy was given before surgery. A left pneumonectomy was performed. Pathology identified a pulmonary synovial sarcoma which rarely occurs in the thorax.
