Synovial sarcoma of lung is a very rare tumor accounting for 0.5% of all primary lung malignancy. It presents clinically with cough, chest pain, shortness of breath, or hemoptysis, with a mass lesion on X-ray and computerized tomography scan. Diagnosis is made by histopathology and immunohistochemistry. Here, we report a case of 48-year-old male, who presented with right-sided chest pain, cough with blood-tinged sputum, and found to have primary pulmonary synovial sarcoma of lung.
