Synovial sarcomas represent 3-5% of primary heart sarcomas. They can be of three different types: biphasic, monophasic and poorly differentiated, of which the monophasic type is the most common in the heart. These cases are positive for vimentin and EMA in most cases and less frequently positive for pan-cytokeratins, synaptophysin and CD99. This particular case was strongly BCL2 positive.
