Not only do they simulate valvular disease of the heart, but they are sometimes accompanied by a non-specific syndrome of fever, anemia, clubbing of the fingers and toes, hemoptysis, and a raised erythrocyte sedimentation rate (ESR).

This report is of a left atrial sarcoma which presented in this way.
