Insights
Carney complex can manifest as digital vasculitis and Raynaud's phenomenon. A pediatric case highlights a left atrial myxoma causing these symptoms, emphasizing the need for cardiac evaluation in similar presentations.
Area of Science:
- Cardiology
- Dermatology
- Genetics
Background:
- Carney complex is a rare genetic disorder predisposing individuals to myxomas and spotty skin pigmentation.
- Digital vasculitis and Raynaud's phenomenon are vascular conditions affecting the extremities.
Observation:
- A 12-year-old male presented with a 6-week history of digital vasculitis, including finger color changes and palmar/plantar macules.
- Physical examination revealed skin findings consistent with Carney complex and an abnormal cardiac examination.
Findings:
- Echocardiography revealed a large left atrial mass causing diastolic obstruction and mitral valve insufficiency.
- Surgical excision confirmed a pedunculated myxoma, consistent with Carney complex.
Implications:
- This case underscores the importance of considering Carney complex in pediatric patients with apparent vasculitis.
- Left atrial myxoma can present atypically, mimicking vascular disorders and necessitating thorough cardiac assessment.
- Early diagnosis and management of Carney complex are crucial for preventing cardiac complications.
Abstract:
A 12-year-old male presented with a 6-week history of apparent digital vasculitis with color changes of the distal fingers and erythematous macules of the palms and soles. Physical examination revealed skin findings of Carney complex and an abnormal cardiac examination. Echocardiography demonstrated a large left atrial mass, which caused partial obstruction during diastole and moderate mitral valve insufficiency. Surgical excision and pathological examination of the mass confirmed the presence of a large, peduculated myxoma. This case illustrates the presentation of Carney complex with left atrial myxoma as apparent vasculitis and Raynaud's phenomenon.

Jugular Venous Pressure (JVP) Measurement
Position the patient at a thirty- to forty-five-degree angle or in a semi-fowler's position. Look for the highest point of pulsation in the internal jugular vein and measure the vertical distance to the angle of Loius or sternal angle. A normal JVP is 3-4 cm above the...
