American Academy of Pediatrics Releases Report on Infantile Hemangiomas.

A collection of Practice Guidelines published in AFP is available at http:// www.aafp.org/afp/ practguide. Infantile hemangiomas, the most common tumors of childhood, are vascular neoplasms characterized by abnormal proliferation of endothelial cells and aberrant blood vessel architecture. The incidence of infantile hemangiomas is approximately 5%. Congenital hemangiomas are biologically and behaviorally distinct from infantile hemangiomas because they are fully grown at birth and can be rapidly involuting or noninvoluting. The American Academy of Pediatrics has published this report to provide an update on diagnosing and managing infantile hemangiomas.
