Telangiectasias are small blood vessels that are located under the surface of the skin. The vessels may appear red, purple, or blue. The most common places these are seen include the face, upper chest, and neck. Related vessels can be found in the legs, called spider veins. Removal is usually for cosmetic reasons.

There are many causes of telangiectasia, including heredity, sun damage, hot and spicy foods, emotions, hormones, some medications, and adult acne.

Treatment of these lesions may include lasers or sclerotherapy. Sclerotherapy is a procedure in which a small needle is used to inject medication into the vessels, causing them to shrink. New vessels may continue to develop throughout the person's life, depending on the underlying cause of the lesions.
