Telangiectasia

Telangiectasia represent small, persistently dilated blood vessels in the skin. Telangiectasia can occur as a primary process, as a result of damage to the skin from the sun or following radiation therapy, or secondary to a systemic disease. Multiple telangiectasia should prompt referral to evaluate for an underlying cause such as hereditary hemorrhagic telangiectasia (HHT), ataxia-telangectiasia and others. Treatment of telangiectasia is often not necessary, but can include cosmetic camouflage, vascular laser, and sclerotherapy.
