Venous malformations (VMs) represent the most common congenital vascular malformations and are estimated to occur in 1-5 of every 10 000 births. They are the third most common congenital vascular lesion to occur in the head / neck region, with infantile hemangiomas and lymphatic malformations being more common. VMs can involve the skin, subcutaneous tissue, and mucosa. They range in presentation from asymptomatic venous varicosities to exophytic deforming tumors involving the skin, internal organs, and bones, with mass effect on adjacent structures. Visible cutaneous changes may belie much deeper involvement in any given area.
