Background:
Nevus of Ota (NO) is a hamartoma of dermal melanocytes usually presents as unilateral blue, gray or brown macules or patches. It can impose a high burden of cosmetic and psychological disturbances in affected individuals. Q-Switched lasers appear to be an effective treatment for this kind of dermal melanocytosis. Multicolored Ota nevus is a rare variant of this kind of nevus and its treatment may be more challenging compared with unicolor lesions. Herein we report a 21-year-old woman with a multicolored nevus of Ota (blue and brown), which showed a dramatic response to a combination of 1,064 nm and 532 nm Q-Switched Nd:YAG lasers. We also discuss different aspects of the Q-switched laser application of Ota nevus treatment. We also focus on laser combination therapy to treat the nevus of Ota.
