Vascular Anomalies, ISSVA Classification

2 categories: vascular tumors or vascular malformations. Distinction determines therapy.

Vascular Tumors

• infantile hemangiomas: grow rapidly after birth, GLUT1+
• congenital hemangiomas (RICH and NICH): fully mature at birth, GLUT1-
• Tufted angioma
• Kaposiform hemangioendothelioma
• Spindle cell hemangioendotheliomas
• Dermatologic acquired vascular tumors

Vascular malformations (slow)

• capillary malformation (port-wine stain, telangiectasia, angiokeratoma)
• venous malformation
• lymphatic malformation

Vascular malformations (fast)

• arterial malformation
