You will usually see them on below your knees and on the surface of your ankles and thighs and around your nose, cheeks, or chin on your face. They can also be seen on the whites of your eyes. Although they are usually harmless there is also a chance that they can occur in your brain and cause some major problems from bleeding. On your legs they are sometimes referred to as spider veins.

Telangiectasia Symptoms

Many times when these lesions develop on people that are healthy they usually do not cause any symptoms. What you might see is that this permanent dilation can cause a reddish discoloration in the surrounding skin. This happens because of the small lesions that develop.

  • They can look unattractive and cause discomfort
  • The formation of these lesions is gradually
  • They can be painful because of the pressure on the venules
  • Itching

Telangiectasia Causes

The exact cause of telangiectasia is not known but according to researchers they believe that it could be because of overexposure to the sun. The reason that researchers think this is because these lesions will usually appear in places that are more exposed to sunlight. Some of the other causes that can possibly cause telangiectasia can include:

  • Pregnancy because this can put a large amount of pressure on your venules
  • Aging because as you get older the blood vessels start to weaken
  • Alcoholism which can affect the flow of blood in your vessels

They can be seen with a number of other diseases like acne rosacea, birthmarks, prolonged use of topical or oral corticosteroids, and long time use of oral contraceptives, several different inherited disorders, and more. It has also been found that telangiectasia can be caused by routine damage to your skin or just appear spontaneously.

Telangiectasia Treatment

If you notice telangiectasia on your skin it is advisable that you see your physician to rule out the presence of an inherited or underlying condition. There are also treatments that your dermatologist can do if they are detracting from your personal appearance your dermatologist could treat it by electrosurgery, or a pulsed dye laser. If it is not caused by an underlying condition you could cover it up by using makeup.

Other methods to treat telangiectasia can include:

Laser ablation

The laser targets the vessels that have been widened and seals them. With this treatment there is little pain and a short recovery. This the type of treatment used on your face.

Surgery

With surgery the widened vessels can be removed but this treatment it can take you a long time to recover and can be painful.

Sclerotherapy

This is a cosmetic surgery in which the dermatologist injects a sclerosing agent into your veins. The dermatologist uses one injection for every one inch of vein and as a result you may need between five to fifty injections to treat telangiectasia. This is the treatment that is used on your legs.

Because they are not attractive looking and are causing discomfort many decide to have them removed. This is accomplished by causing some type of damage to your blood vessel, forcing the blood vessel to scar or collapse. By doing this it will decrease the appearance of the patterns or red marks on your skin.
