Carney complex with right ventricular myxoma following second excision of left atrial myxoma.

We report a case of Carney complex with massive right ventricular myxoma after two-time excision of a left atrial myxoma. The patient was a 45-year-old woman with pyrexia. She temporarily lost consciousness during examination, and echocardiography and computed tomography (CT) showed a massive tumor in the right ventricle. Loss of consciousness was determined to be caused by intracardiac obstruction of blood flow due to the tumor, and corrective surgery was performed. Pathological findings indicated myxoma with no malignancy. Myxomas are benign, but there is frequent recurrence of tumors associated with Carney complex. Because her myxomas were accompanied by unusual skin pigmentation, she was diagnosed with Carney complex. Carney complex has a high rate of myxoma recurrence, and often runs in families. In all cases, it is necessary to observe the patient's course closely.
