Progressive disseminated essential telangiectasia and erythrosis interfollicularis colli as examples for successful treatment with a high-intensity flashlamp.

BACKGROUND Treatment of progressive disseminated essential telangiectasia and erythrosis interfollicularis colli by flashlamp pulsed dye laser frequently results in a mottled appearance and often leads to hypo- or hyperpigmentation after treatment. Furthermore, treatment is time-consuming due to the small spot size. OBJECTIVE To report the successful removal of thin vessels in patients with the above-mentioned indications by an intense pulsed light (IPL) source. METHODS Four patients with progressive disseminated telangiectasia on the extremities and 5 patients with erythrosis interfollicularis colli were treated with IPL. RESULTS A clearance of up to 90% of the telangiectasias was achieved. CONCLUSION The superficial, thin vessels of progressive disseminated essential telangiectasia and erythrosis interfollicularis colli can be successfully treated by IPL.
