Abstract： To the Editor:Unilateral nevoid telangiectasia (UNT) is a rare vascular dermatosis characterized by telangiectasia that is distributed in a linear,unilateral pattern.The etiology of this condition is not yet fully understood,although high estrogen levels are thought to be related to its development.[1] Affected patients often resort to treatment because of cosmetic distress.Pulsed dye laser (PDL) therapies have been employed to treat various vascular lesions,such as port-wine stains (PWS),hemangioma,spider angioma,and angiokeratoma.PDL modalities have the advantage of achieving selective photothermolysis,leading to selective vascular injury without unwanted thermal damage to surrounding tissue.[2] Sharma and Khandpur have previously treated six UNT cases with PDL and reported that good to excellent lighting was achieved in five of these cases after 2 to 5 sessions.
