Cardiac Tumors T2 Rudolph's Pediatrics, 22e YR 2011 FD 2011 PB The McGraw-Hill Companies PP New York, NY SN 978-0-07-149723-7 LK accesspediatrics.mhmedical.com/content.aspx?aid=7048441 RD 2024/10/05 AB Primary cardiac tumors are rare at any age. About 90% are benign, and 10% are malignant, most of them sarcomas. These tumors are found mainly in the heart, but can occur in the pericardium or the great arteries. Secondary cardiac involvement from malignant tumors of adjacent organs (lung, thymus) or from kidney (Wilms tumor) or liver, or even remote organs, are also seen. The main types of tumors and age groups at which they occur are shown in eTable 487.1.
