Tricuspid Papillary Fibroelastoma Mimicking Tricuspid Vegetation in a Patient with Severe Neutropenia.
We report a 72-year-old male with known myelodysplastic syndrome who presented to the emergency department with a 7-day history of fever and dyspnea. Echocardiography revealed a round echogenic mass 13×16 mm in size attached to the atrial side of the tricuspid valve. Considering the high risk of infective endocarditis in the patient with a low absolute neutrophil count (130/mm(3)), emergency surgery was performed. Intraoperatively, a single gelatinous neoplasm was resected, and subsequent reconstruction of the involved leaflet was accomplished using autologous pericardium. The tumor was pathologically confirmed as papillary fibroelastoma with no evidence of infective endocarditis. Papillary fibroelastoma is a rare cardiac neoplasm that occurs in either the mitral or aortic valves. Interestingly, a few cases of tricuspid valve papillary fibroelastoma have been reported so far. Similar echocardiographic findings between vegetation and tricuspid valve neoplasm make it difficult to distinguish these two disease entities.
