Recurrence of unilateral naevoid telangiectatic syndrome following treatment with the pulsed dye laser.

Abstract

Unilateral naevoid telangiectatic syndrome (UNTS) was first described in 1899 and is characterized by the dermatomal distribution of telangiectasia. It is broadly divided into congenital and acquired forms based upon the time of presentation. To date no effective treatment has been reported for this condition. In view of the vascular component of this eruption, it was felt that the pulsed dye laser (PDL), 585 nm, may have a role to play in the selective photothermolysis of these lesions. The treatment of five patients with acquired UNTS using the PDL is described. Based upon the findings it is concluded that the PDL is an effective treatment for UNTS; however, the clinical response is short lived with a 100% recurrence noted in all cases. Possible explanations for this condition are also briefly discussed.
