What is generalised essential telangiectasia?

Telangiectasia is the term used to describe the permanent dilation of small blood vessels, creating small, red markings on the skin and mucous membranes. Essential or primary telangiectasia refers to capillary dilation of unknown origin. No preceding or coexisting skin or internal disease is present. Generalised essential telangiectasia is just one type of primary telangiectasia and is given this name because of its widespread distribution pattern over the body. Other primary telangiectases include angioma serpiginosum, ataxia-telangiectasia, angiomas and spider naevi.

What are the signs and symptoms?

Generalised essential telangiectasia is characterised by the following:

Why does it happen and who is at risk?

The cause of telangiectasia remains unclear. Sometimes there may be a family history. It usually first appears around 40-50 years of age and affects women more often than men.

It is not associated with varicose veins or other venous disorders. Environmental factors such as sun exposure may possibly play a part in its development.

Telangiectases may be slow or fast to develop and usually spread to other parts of the body. They persist indefinitely and do not spontaneously resolve. Apart from the emotional distress that may be caused by the telangiectases, generalised essential telangiectasia is a benign condition that is not associated with any physical complications.

What treatments are available?

It is very difficult to remove the telangiectases of generalised essential telangiectasia. Patients whom are self-conscious may use cover-up cosmetics or self-tanning lotions to hide the telangiectases.

They are usually unresponsive to sclerotherapy. Recently, various vascular lasers (frequency-doubled Nd-YAG, copper bromide and pulse-dye lasers) have shown promise in the treatment of generalised essential telangiectasia.
