Key features

ย„Although both were once called โ€œangiomasโ€, vascular malforma- tions differ from the vascular tumors seen in infants and children

ย„In slow-flow malformations, capillaries, veins, and/or lymphatic channels are anomalous; most lesions are either apparent at birth or become evident within the first few months or years of life

ย„In fast-flow malformations, there is arteriovenous shunting; some lesions are apparent at birth, but the majority become evident later in childhood or adulthood

ย„Vascular malformations are lifelong and may worsen over time, creating cosmetic consequences and functional impairment

ย„Vascular malformations are occasionally found together with other abnormalities as a part of a complex syndrome
