Vascular birthmarks

For this reason, vascular marks tend to be red, bluish, or purplish in color. There are two major types of vascular birthmarks: hemangiomas (heh-Man-jee-OH-muhz) and vascular malformations. A hemangioma is a blood vessel tumor that's normally harmless. Most hemangiomas occur in the form of so-called ""strawberry marks,"" named for their red, bumpy appearance. Hemangiomas usually go away on their own by age nine or 10, though a few may persist longer.

If the hemangioma grows internally and interferes with functions like vision or breathing, doctors may need to remove it rather than wait for it to fade. Vascular malformations include problems such as venous (VEEN-uhs) malformations, in which large veins cause soft lumps with or without color; lymphatic malformations, in which lymph system vessels swell in response to fluid build-up; and port wine stains. Port wine stains are usually found on the face or neck and typically begin as flat stains of pink or red which later turn purple. Most vascular malformations will enlarge in size unless they're treated.
