[A case of tricuspid valvular myxoma in a child]

A six-year old boy had hospitalization because of cardiac murmur and syncope attack. Laboratory data including immunoglobulin and erythrocyte sedimentation rate were normal, but echocardiography and cardioangiography indicated tricuspid valvular myxoma in the right atrium. The tumor was successfully removed with the septal tricuspid valve using the cardiopulmonary bypass. The tumor was 18 x 20 x 12 mm in size and pathological findings showed a myxoma originated from tricuspid valve. Now he shows normal cardiac function and no recurrent sign of tumor. There has been reported a few cases of valvular myxoma in Japan. However, this is the first case which was successfully resected by surgery.
