  Fig. 1 Congenital melanocytic nevus (CMN) in a 25-year-old man. (A) Before treatment: a solitary, 1-cm brown patch is visible on the right alar area of the nose. (B) One year after the final treatment session, the skin lesions resolved with minimal scarring. (C) CMN in a 5-month-old boy. Before treatment, a solitary, 1.5~2-cm, well-demarcated, brown patch is visible on the forearm. (D) The pinhole method was used to create 1-mm holes deep in the dermis. (E) Minimal mottled hyperpigmentation was observed 6 months after the final laser treatment.

  Fig. 2 Nevus sebaceous lesions in a 40-year-old woman. (A) Before treatment, two 2.5-cm, well-demarcated, yellow, verrucous plaques were visible on the right side of the forehead. (B) Deep line- and doughnut-shaped holes were created to remove the nevus sebaceus lesions. (C) Six months after the final laser treatment, the patient showed marked improvement, with only mild hypopigmentation.
