Primary malignant cardiac tumors in children.

A child with a primary malignant cardiac tumor prompted a review of all 13 cases reported in Great Britain from 1962-1983. Only 4 definitely malignant tumors were identified, giving an incidence of between 1 in 38 and 1 in 90 x 10(6). All 4 patients died without evidence of metastases. Cardiac transplantation should be considered.
