Pulmonary valve papillary fibroelastoma. A case report and review of the literature.

○ Papillary fibroelastomas are rare and benign cardiac tumors that typically affect the cardiac valves. To the best of our knowledge, the English literature contains only 1 case report of pulmonary valve fibroelastoma diagnosed by echocardiogram and confirmed by surgical resection. There is a paucity of pathology literature on this subject. We describe an additional case of pulmonary valve fibroelastoma diagnosed by transesophageal echocardiography and magnetic resonance imaging confirmed by pathologic examination in a patient who also had a thymoma.
