Cardiac myxoma, light micrograph
Cardiac myxoma, light micrograph. Cardiac myxoma is the most common primary tumour of the heart (50% of all cases). It is benign (non-cancerous) with no known potential for malignant transformation. The most common location is the left atrium. Sporadic cardiac myxomas (90-95% cases) are usually single and occur more commonly in middle-aged women (avg. age 50 years). Familial tumours (5-10% cases) occur in younger patients, may be multicentric (30% of cases), and are slightly more common in males. They are seen in the setting of an autosomal dominant multisystem syndrome called Carney complex.
