Picture of Port Wine Stain
The photo depicts a port wine stain on the cheek of an infant. Port wine stains are caused by an abnormal grouping of capillaries in the skin. Port wine stains in infancy are amenable to high-energy pulsed-dye laser treatments, which are safe and effective in improving the appearance of these birthmarks.
