Cutaneous eruption in a patient with cardiac myxoma.

Atrial myxoma was diagnosed in a young woman who had cutaneous and constitutional manifestations clinically suggestive of cutaneous vasculitis without cardiac signs or symptoms. Scrupulous physical and laboratory examinations excluded additional medical disorders. The patient was totally cured by surgical removal of the tumor. Various aspects of the association of cardiac myxoma with dermatological findings are discussed, emphasizing the importance of echocardiography in the diagnostic workup of various skin abnormalities, including unexplained vasculitis, even in the absence of cardiac findings.
