Abstract
- A congenital melanocytic nevus (CMN) is present at birth in approximately 1% of newborn infants. Treating CMN with a single laser without complications is very difficult because of the deep nature of the pigments in this lesion. A 5-year-old girl presented with a single 3x6 cm sized dark brown plaque on the right lower leg; some black hairs were also evident inside the pigmented lesion. She received ten treatments with intense pulsed light and then four treatments with Q-switched Nd:YAG laser. In order to achieve the chemoexfoliation, a topically modified Kligman formula (Trilusta(R)) was applied to the pigmented lesion twice a day for 6 months. Complete pigment clearance and hair removal were obtained and no side effects were observed. These results have been maintained for up to 18 months follow-up. We suggest that this combined treatment will be a good option for treating CMN with minimal scarring.
