What is Telangiectasia?
Telangiectasias are dilated as well as superficial blood vessels which are widely open and are usually located in the outer skin layer. Usually seen on the legs they are frequently referred to as spider veins. They can occur in rosacea, as well as some systemic disease such as ataxia-telangiectasia, sclerodema and also sometimes in long-term therapy with topical fluorinated coricosteroids. Most cases of telangiectasias are of unknown causes and could be some component of disorders which are inherited such as hereditary hemorrhagic telangiectasia.
Telangiectsias can occur anywhere on the body and can easily be seen in the mucous membranes, whites of the eyes and in the skin. They are fairly common on the face – cheeks, nose and chin – as well as legs particularly just below the knees and ankles. They normally do not cause any symptoms. But there are some telangiectasias which do bleed and can cause some problems. They can also develop in the brain and this can cause major problems if bleeding develops.
Telangiectasias are blue, purple or red linear lines which measure les than 1 to 3 mm in width and several millimeters to centimeters in length. They often disappear temporarily when you press on them with your finger.
Causes can include:
- Sun exposure
- Alcohol use
Diseases linked with this problem include:
- Cutis marmorata telangiectatica congenita
- Blood syndrome
- Klippel-Trenaunay-Weber syndrome
- Heredity hemorrhagic telangiectasia or Osler-Weber-Rendu syndrome
- Nevus flammeus such as port-wine stain
- Sturge-Weber disease
- Spider angiomas
No treatment is needed unless the appearance is troublesome.
