Yamada-Kanazawa S, Jinnin M, Fukushima S


Nevus of Ota is a dermal melanocytosis that consists of blue-brown spots, patches and plaques along the distribution of the first and second branches of trigeminal nerve. The efficacy of Q-switched ruby laser treatment against nevus of Ota on dark skin has not been described. The present case, a 2-monthold Indonesian girl, showed rare auricular involvement. Because ear has complicated steric structure, whose skin is sensitive and thin, pain and inflammatory reaction are inevitable. We discussed the difficulty of laser treatments on auricular lesions.
