AB Vascular  anomalies  commonly  present  as  birthmarks.1  Their  classification  has  historically  been  problematic,  with  contradictory  and  confusing  terminology  and  nomenclature.  Although  several  classification  schemes  exist,  the  most  widely  accepted  and  comprehensive  is  the  International  Society  for  the  Study  of  Vascular  Anomalies  (ISSVA)  classification,  updated  in  2014,  to  incorporate  clinical,  imaging,  histologic  and  (where  known)  genetic  characteristics.1,2  Vascular  anomalies  are  broadly  divided  into  vascular  malformations  and  vascular  tumors.3  Vascular  malformations  (see  Chap.  147)  are  errors  of  vascular  morphogenesis  whereas  infantile  hemangiomas  and  other  vascular  tumors  are  proliferative.  Vascular  tumors  in  the  current  ISSVA  classification  are  subdivided  into  (a)  benign,  (b)  locally  aggressive  or  borderline,  and  (c)  malignant;  each  has  unique  features  based  upon  histology,  biology,  clinical  appearance,  behavior,  prognosis,  and  treatment  (Table  118-1).
