Spider Telangiectasia

Overview
  • Spider Telangiectasias are non-neoplastic ectasias, or localized dilations of pre-existing blood vessels that produce small, focal red lesions and may be apparent in the skin or mucous membranes. Spider Telangiectasias represent localized dilations of arterioles that display a radial spread. These lesions are often pulsatile and fade when pressure is applied to them. Athough their pathogenesis is not understood, high levels of estrogen are thought to play a role as they tend to appear in the context of pregnancy or cirrhosis.
