We compared the effectiveness of the UltraPulse CO 2 Laser (Coherent Laser Corp, Palo Alto, California) continuous-wave mode with the ultrapulse mode in treating verrucous epidermal nevi in 4 patients with Fitzpatrick skin types IV to VI (1 of these patients was lost to follow-up). For each patient, a continuous plaque of nevus was taken and divided into 3 equal parts: the superior and inferior parts were randomized to be treated with either the continuous-wave or ultrapulse mode; the middle part was the untreated control. At 1, 4, 12, and 36 weeks, patients were checked for quality of healing and recurrence. Results at the 2 treated sites - epidermal nevi removed almost completely, no significant scarring, no recurrence at 36 weeks - were not significantly different. Continuous-wave and ultrapulse modes seem equally effective in treating verrucous epidermal nevi.
