Cutaneous findings associated with cardiac myxomas

Area of Science:

• Cardiology
• Dermatology
• Oncology

Background:

• Cardiac myxomas, though benign, pose diagnostic challenges.
• Echocardiography has improved detection, but clinical presentation can be misleading.
• These tumors can mimic systemic diseases, delaying diagnosis.

Observation:

• Cardiac myxomas can present with diverse clinical and laboratory findings.
• Cutaneous manifestations are important clues for diagnosis.
• A case of left atrial myxoma with indicative skin lesions is presented.

Findings:

• Cardiac myxomas can cause obstruction and arterial embolism, leading to morbidity and mortality.
• Nonfamilial and familial forms exist.
• Specific skin lesions and multifocal findings warrant consideration of cardiac myxoma.

Implications:

• Early diagnosis and surgical excision of cardiac myxomas can prevent long-term sequelae.
• Clinicians should consider cardiac myxoma in differential diagnoses with suggestive cutaneous findings.
• Increased awareness of varied presentations can improve patient outcomes.
