Telangiectasias are small, widened blood vessels on the skin. They are usually harmless, but may be associated with several diseases. Angioma serpiginosum appears most frequently in adolescent females and consists of small, superficial telangiectasias vascular lesions in the skin. Essential telangiectasia often appears over the lower extremities, beginning in adolescence, and continuing throughout adult life. Telangiectasias of the skin occur in multiple conditions. Thin skin secondary to long-term steroid use or aging, collagen vascular disease, and hormonal variation particularly estrogen are all implicated in the formation of telangiectasias.
Bleeding and Bruising: A Diagnostic Work-up
Telangiectasias , also known as spider veins , are small dilated blood vessels  that can occur near the surface of the skin or mucous membranes , measuring between 0. Dilated blood vessels can also develop on the legs, although when they occur on the legs, they often have underlying venous reflux or "hidden varicose veins" see Venous hypertension section below. When found on the legs, they are found specifically on the upper thigh, below the knee joint and around the ankles. Many patients who suffer with spider veins seek the assistance of physicians who specialize in vein care or peripheral vascular disease.
When Joyce Kierstead first began to notice the road map of tiny red lines appearing on her chin in her late 20s, she didn't realize it would lead her down the wrong path. She was often told her problem was that she was not cleaning her skin properly, or that she needed a better foundation. It was the network of visible blood vessels on her face that bothered Rita Edwards the most. As a frequent blusher, she was accustomed to having "high color" on her face, but this was more than she could bear. Even though she doesn't like to wear makeup, Rita tried foundations and creams to cover her blemishes, redness and blood vessels.
