Abstract
PORT-WINE STAINS (PWSs)—a congenital, progressive ectasia of the superficial cutaneous vascular plexus—appear in 0.3% to 0.5% of newborns. At birth, PWSs are typically flat, sharply delineated, light-red lesions, often occupying large surface areas. Facial PWSs often occur in the region of the first and second trigeminal nerves. With time, these superficial vessels become more and more ectatic resulting in a darkening and thickening of the PWS, occasionally progressing to the nodular type with increasing age.1-5
