Diagnostic dilemma of cardiac synovial sarcoma – Primary or secondary

Cardiac synovial sarcomas are rare tumors. Few cases are reported in literature. They commonly present with heart failure. Surgery is the primary modality of treatment where possible. Radiation and chemotherapy are used for local and systemic control as indicated. We present a rare case of synovial sarcoma with simultaneous cardiac and soft tissue involvement. The case is presented for its rarity and diagnostic difficulty in determining the primary site of origin.
