Treatment of nevus of Ota with autologous-cultured epithelium grafting combined with dermabrasion.

Nevus of Ota is an anomaly of the dermal melanocytes, which lies primarily in the deep dermis. It causes discoloration of the face and induces a remarkable disfigurement to the patients. This report demonstrates the favorable results of 3 male patients treated with autologous-cultured epithelium grafting combined with dermabrasion. The lesions on the cheek, forehead, and temple were dermabraded to the deep dermal layer. The cultured epithelium obtained from preauricular skin or medial upper arm were grafted on the wounds. The grafts took well, and most of the grafted site healed after 1 week. Facial appearances improved remarkably. There was minimal scar formation and minimal recurrence of nevus cell. After long-term follow-up, the grafted sites resembled the adjacent normal face skin in terms of appearance and texture.
