Y1 - 2018 N1 - T2 - Rudolph's Pediatrics, 23e AB - Vascular tumors in children are rare and their classification has been difficult, especially in the pediatric population, because of their unusual morphologic appearance, diverse clinical behavior, and lack of independent stratification for pediatric tumors in the World Health Organization’s (WHO) 2013 classification system. In 2014, the International Society for the Study of Vascular Anomalies (ISSVA) updated their classification system. Although the ISSVA classification of vascular tumors is based on the WHO classification (refer to Tables 458-1 and 458-2), it uses more precise terminology and phenotypes.
