Primary synovial sarcoma of lung is an extremely rare tumor. We report a case of a 50 year old male, who complained shortness of breath and hemoptysis. He had heterogeneously enhancing soft tissue density in right upper lobe. Trucut biopsy revealed spindle cell neoplasm and he underwent right lobectomy. Histopathological examination of lobectomy specimen revealed monophasic variant of synovial sarcoma. On immunohistochemistry tumor cells positive for vimentin, bcl-2, CD99 and immunonegative for cytokeratin. Based on clinical, imageological, histopathology and immunohistochemistry finally concluded it as primary synovial sarcoma of lung.
