Definition of Telangiectasis

telangiectasisTelangiectasis is a weblike network of blood vessels that becomes visible just below the surface of the skin, commonly called spider veins.

Sometimes spider veins are present from birth or early childhood as a birthmark, though more commonly develops later in life as a manifestation of chronic sun exposure.

Telangiectasis generally has no adverse health effects, though many people find the lesions cosmetically unacceptable. When it occurs on the face, dermatologists use laser therapy or fine cautery.

For spider veins on the legs, the most common treatment is sclerotherapy in which the dermatologist injects the telangiectasis with a chemical that irritates the blood vessels, causing them to scar. Over time the discoloration fades. Laser therapy may be a therapeutic option.
