Question

The most common primary benign cardiac tumor found in children is:

A. Myxoma
B. Papilloma
C. Rhabdomyoma
D. Rhabdomyosarcoma

Answer 1

The most common primary benign cardiac tumor in children is Rhabdomyoma, usually associated with tuberous sclerosis complex and different from hypertrophic cardiomyopathy, a muscle enlargement without a known cause.

Step-by-step explanation:

The most common primary benign cardiac tumor found in children is C. Rhabdomyoma. Rhabdomyomas are often found during fetal development or infancy and comprise a large proportion of cardiac tumors in children. They are generally associated with tuberous sclerosis complex (TSC), a genetic disorder that affects multiple systems. In contrast, myxomas are the most common primary cardiac tumors in adults but are rare in children. Unlike hypertrophic cardiomyopathy, which is a pathological enlargement of the heart's muscular wall often without a known cause, rhabdomyomas are discrete masses arising from cardiac myocytes.
