ABSTRACT: Nevus of Ota is a benign dermal melanocytic condition characterized by unilateral blue-grey facial hyperpigmentation, often associated with cosmetic concern. Laser therapy, particularly the Q-switched Nd:YAG (QSNY) laser, is considered the treatment of choice. We report a case of a 25-year-old woman with Fitzpatrick skin type IV who presented with congenital Nevus of Ota involving the right cheek. She underwent 20 sessions of 1064 nm QSNY laser at 4-week intervals, with progressive lightening observed after each session. Marked clinical improvement was achieved after completion of treatment, with no adverse effects observed. This case demonstrates a favourable outcome with QSNY 1064 nm laser for Nevus of Ota, suggesting that it may be a safe and effective treatment option in similar patients.
