Capillary malformations are present at birth and appear as flat, pink, red, or purplish lesions. Port-wine stains are flat, reddish to purple lesions appearing anywhere on the body. Lesions become darker and more palpable with time often becoming quite hyperplastic by late middle age , but the lateral extent increases only in proportion to the growth of the patient. Port-wine stains of the trigeminal area may be a component of the Sturge-Weber syndrome in which a similar vascular lesion appears on the underlying meninges and cerebral cortex and is associated with seizures. Diagnosis of capillary malformations is made clinically. Imaging studies may be indicated, depending on findings, to diagnose associated syndromes eg, Sturge-Weber syndrome.
