[A case of "familial" type cardiac myxoma].

We report a case of "Familial" type cardiac myxoma observed in mother and daughter. The mother had myxomas in the bilateral atrium, which were completely resected together with the peripheral tissue. Her first child (daughter) had myxoma in the outflow tract of the right ventricle. The wide range resection of tumor and tumor pedicle with the free wall of right ventricle and ventricular septum was tried, however, the resection range was limited for anatomical restriction. Cardiac echo, MRI and superhigh-speed CT are useful for detection of the site of tumor in presence, its mobility and the site to which the pedicle adhered and did not make us recognize necessity of cardiac catheter test. When "Familial" or "Complex" type lesion is suspected, it is necessary to investigate carefully other sites except a tissue with the tumor and the patient's family and recurrence after tumor resection.
