Cardiac papillary fibroelastoma(CPF)is a rare benign cardiac tumor. It commonly arises from the left side heart valve. We present two rare cases of CPF that originating from the right side of the heart confirmed by surgical resection. Case 1:A 67-year-old man was admitted for surgical resection of a cardiac tumor located in the right atrium. Transesophageal echocardiography revealed a mobile mass attached on the anterior leaflet of the tricuspid valve. The tumor was resected by open heart surgery. Histopathologic examination confirmed the tumor to be a CPF. Case 2:A 68-year-old man was admitted for surgical resection of a tumor occurred from the tricuspid valve. Transthoracic echocardiography revealed a tumor attached to the medial leaflet. The tumor was resected. Histopathologic examination confirmed it to be a calcified mass. However, the surface of tumor had many papillary projections macroscopically. We redo the histopathologic examination, and confirmed the tumor as a CPF finally. In both cases, postoperative courses were uneventful.
