Port-wine stain (also known as nevus flammeus) is a vascular anomaly present at birth, characterized by a pink to purple mark on the skin, which can vary in size. The name "port-wine" is derived from the color of Port wine, which the stain often resembles.

Causes

Port-wine stains are caused by an abnormal development of blood vessels (vascular malformation) in the skin. The exact cause of this abnormal development is not known, but it is believed to be caused by a genetic mutation. Port-wine stains are not caused by trauma, injury, or any other known environmental factors.

Symptoms

The primary symptom of a port-wine stain is a visible mark on the skin, usually pink to purple in color. The mark can vary in size, and can be located anywhere on the body, but is most commonly found on the face. The skin under and around the port-wine stain may be thicker than normal, and may have a pebbly appearance.

Treatment

Treatment for port-wine stains includes laser therapy, which can lighten the color of the stain and make it less noticeable. Other treatments may include dermabrasion, chemical peel, and surgery. However, these treatments are not always successful and may have side effects.

Prognosis

Port-wine stains are permanent and may become darker and thicker with age. However, they are not life-threatening and do not cause any physical health problems. Some people with port-wine stains may experience psychological distress due to the appearance of the stain.
