SPIDER VEINS & TELANGIECTASIA
Telangiectasias or angioectasias (also known as spider veins) are small dilated blood vessels near the surface of the skin or mucous membranes, measuring between 0.5 and 1 millimeter in diameter. They can develop anywhere on the body but are commonly seen on the face around the nose, cheeks, and chin. They can also develop on the legs, specifically on the upper thigh, below the knee joint, and around the ankles

Nevus flammeus such as port-wine stain
PORT WINE STAIN
A port-wine stain or nevus flammeus is almost always a birthmark. It is caused by a vascular anomaly (a capillary malformation in the skin).
Port-wine stains ordinarily persist throughout life. The area of skin affected grows in proportion to general growth. Port-wine stains occur most often on the face but can appear anywhere on the body, particularly on the neck and upper trunk.Early stains are usually flat and pink in appearance. As the child matures, the color may deepen to a dark red or purplish color. In adulthood, thickening of the lesion or the development of small lumps may occur.They are called port wine for their reddish color.
Early port-wine stains are usually flat and pink in appearance. As the child gets older, the color may deepen to a dark red or purplish color. They occur most often on the face but can appear anywhere on the body. Over time, the area can become thickened and take on a cobblestone-like appearance.
Many treatments have been tried for port-wine stains, including freezing, surgery, radiation, and tattooing.
Laser therapy is most successful in eliminating port-wine stains. It is the only method that can destroy the tiny blood vessels in the skin without significantly damaging the skin. The exact type of laser used depends on the person’s age and particular port-wine stain.
