Describe telangiectasis.

Telangiectasis consists of a new growth or enlargement of the cutaneous capillaries, usually appearing during middle adult life, and seated, for the most part, about the face.

To what extent may telangiectasis develop?

It may be limited to a red dot or point, with several small radiating capillaries (nÆvus araneus, spider nÆvus), or a whole region, usually the face, may show numerous scattered or closely-set capillary enlargements or new formations (rosacea). The latter is frequently associated with acne (acne rosacea).

The etiology is obscure.

What is the treatment of telangiectasis?

Destruction of the vessels by electrolysis or by the knife. (See treatment of acne rosacea.)
