A 56-year-old man had a 6 x 5-cm mass originating from the fossa ovalis in the atrial septum found by echocardiography and multiple enlarging scalp masses. The mass had a regular surface and was prolapsing into the mitral valve during diastole. The tumor was successfully treated by surgical excision, which revealed a well-defined mass with a narrow-base stalk originating from the fossa ovalis in the atrial septum. Histological examination confirmed the diagnosis of myxoma. The scalp masses were also removed surgically; histopathologic examination corresponded to benign trichilemmal cyst. The patient recovered without complication and was discharged 10 days after the operation.
