Cutaneous findings associated with cardiac myxomas.
The clinical diagnosis of cardiac myxomas remains a challenge despite the advent of echocardiographic technology. These tumors may produce a variety of clinical and laboratory findings that can mimic systemic disease and obscure the proper diagnosis. Although histologically benign, cardiac myxomas may cause significant morbidity and mortality via intracardiac obstruction and arterial embolism. Possible long-term sequelae may be avoided by early recognition and prompt surgical excision. We briefly review the various findings associated with cardiac myxomas (nonfamilial and familial) with emphasis on cutaneous presentations. An illustrative case of left atrial myxoma with cutaneous findings contributing to the diagnosis is discussed. Certain skin lesions and multifocal clinical findings should alert the clinician to consider cardiac myxoma in the differential diagnosis.
