Evaluating the therapeutic efficacy of the 595 nm pulsed dye laser system for treating capillary malformations.

Capillary malformations are the most prevalent low-flow vascular abnormalities. We present the case of a 30-year-old woman with a lateral capillary malformation. Dermoscopy showed an erythematous background and rare telangiectatic vessels for less than 5-10% of the entire area examined. The patient underwent a single treatment session with a 595 nm pulsed dye laser (PDL). An excellent immediate response was observed at the end of the session, with a noticeable reduction in the capillary malformation confirmed at clinical follow-up two months later. Dermatoscopic and 3D photographic evaluation before and after laser treatment also documented the disappearance of the erythematous background and telangiectatic vessels.
