Young Blonde Girl With The Forehead Birthmark

• Strawberry mark (Hemangioma)
A hemangioma of infancy (strawberry mark) is a benign self-involuting tumor (swelling or growth) of endothelial cells, the cells that line blood vessels. It usually appears during the first weeks of life and resolves by age 10. In infancy, it is the most common tumor.
• Port-wine stain (Nevus flammeus)
Port-wine stains are present at birth and range from a pale pink in color, to a deep wine-red. Irregular in appearance, they are usually quite large, and caused by a deficiency or absence in the nerve supply to blood vessels. This causes the blood vessels to dilate, and blood to pool or collect in the affected area. Over time, port-wine stains may become thick or develop small ridges or bumps, and do not fade with age. Such birthmarks may have emotional or social repercussions.
