TELANGIECTASIA
A vascular lesion formed by dilatation of a group of small blood vessels. It may appear as a birthmark or become apparent in young children. It may also be caused by long-term sun exposure. Although the lesion may occur anywhere on the skin, it is seen most frequently on the face and thighs. See: illustrationtelangiectatic, adjective

telangiectasia

A local or general increase in the size and number of small blood vessels in the skin. Often incorrectly called ‘broken veins’. Telangiectasia may be present from birth but may be caused by undue exposure to sunlight or may be a feature of ROSACEA, PSORIASIS, LUPUS ERYTHEMATOSUS and DERMATOMYOSITIS.

telangiectasia

A dilatation of small blood vessels (arterioles, capillaries, venules), often multiple in character. Telangiectasias create small red lesions, sometimes spidery in appearance, usually in the skin or mucous membranes, which blanch on pressure. They can develop into naevus flammeus ('port-wine stain'), a birthmark found usually on the head or neck. See Sturge-Weber syndrome.
