Both types are benign. </p> <h3>Rhabdomyomas</h3> <p>Rhabdomyomas (say: RAB-doe-my-OH-muhs) are found in the inside walls of the heart. They are usually multiple. These tumours are usually seen in children under the age of one. Often there are no symptoms, but when there are, they can include heart murmur, arrhythmia and heart failure. </p> <p>More than 75% of rhabdomyomas are seen in children with tuberous sclerosis. This is a genetic condition marked by lesions of the skin and central nervous system, tumour growth and seizures. </p> <p>These tumours usually disappear without treatment and do not become malignant. In general, the outlook is positive.</p> <h3>Fibromas</h3> <p>Fibromas (say: fie-BROE-muhs) usually affect the left ventricle. When these tumours grow, they may get in the way of the mitral and aortic valves, causing valve blockage or leakage. They can also disrupt the heart's electrical system, resulting in arrhythmias. They mainly affect children under the age of six.</p> <p>Fibromas may require surgical intervention.</p> <h3>Other benign heart tumours</h3> <p>Less common tumours seen in children are:</p> <ul> <li>myxomas, which tend to occur in the atria; they are the most common tumour seen in adults</li> <li>teratomas, which occur in the heart sac</li> <li>lipomas, which are fatty tumours</li> </ul> <h2>What are the most common malignant heart tumours in children?</h2> <p>Sarcomas (say: sar-COE-muhs) are malignant heart tumours. These are extremely rare in children. The most common are rhabdomyosarcomas. Other malignant tumours include:</p> <ul> <li>angiosarcomas, which can involve any chamber of the heart but most frequently affect the right atrium</li> <li>fibrosarcomas</li> <li>liposarcomas</li> <li>primary lymphomas</li> </ul> <p>Other less common types of malignant tumours include papillary fibroelastomas, hemangiomas, teratomas, lipomas and lymphomas.
