Vascular Birthmarks generally develop at birth or within the first few weeks of life. They can be flat or raised, brown, red, pink or bluish in color. The exact cause of birthmarks is unknown. The most common types of vascular birthmarks are macular (flat) stains, hemangiomas, and port-wine stains.
Macular stain is the most common which are flat and faint in color. Macular stains do not require treatment for they are a harmless birthmark.
Hemangiomas typically do not appear immediately at birth but rapid growth generally begins during the first six weeks of life. After the first year, most will stop growing, turn white and disappear. Occasionally, a hemangioma, can form an open sore which should be watched closely by a dermatologist to determine further treatment.
Port-Wine Stains appear at birth and are flat, pink, red or have a purplish discoloration. Generally are found on the face, neck, arms or legs and grow proportionately as the child grows. Port-Wine Stains are permanent. Complications and treatment options must be discussed with your dermatologist to determine the most effective plan of treatment.
