- vascular tumors

- vascular malformations

  • simple vascular malformations (fast flow)
    • aneurysm, ectasia, stenosis
    • arteriovenous fistula (AVF)
    • aretrionvenous malformation (AVM)
  • combined vascular malformations
    • AVF
    • AVN

    • CLVM
    • LVM

The International Society for the Study of Vascular Anomalies (ISSVA) divides congenital vascular anomalies into malformations and tumors and subclassified hemangiomas under tumors.

Particularly troublesome is the use of the term hemangioma, commonly used to describe a variety of vascular lesions (both malformations and tumors).
