  • vascular anomalies have been divided into vascular tumours and vascular malformations (1).
    • vascular tumours
      • infantile haemangioma
        • includes superficial and deep infantile angiomas
          • the superficial infantile haemangioma is most commonly known as a 'strawberry' naevus, on account of its usual clinical appearance in the form of a sharply circumscribed oval or round, soft, domed swelling of intense scarlet-red colour
      • congenital haemangioma ( rapidly involuting congenital haemangioma (RICH) and noninvoluting congenital haemangioma (NICH) )
      • tufted angioma
      • kaposiform haemangioendothelioma
      • haemangiopericytoma
      • pyogenic granuloma
      • spindle-cell haemangioendothelioma
    • vascular malformations
      • simple
        • capillary
        • venous
        • lymphatic
        • arterial
      • combined
        • arteriovenous fistula, arteriovenous malformation (AVM), capillary venous malformation, capillary-lymphatic venous malformation, lymphatic venous malformation, capillary AVM, capillary-lymphatic AVM

Vascular malformations are also divided into fast-flow and slow-flow (high flow and low flow) lesions depending on the vascular components and flow characteristics (1,2):

  • fast-flow - mainly arterial channels including arteriovenous malformations, arteriovenous fistulas, capillary AVM
  • slow-flow - capillary, venous, lymphatic channels and combinations
