Nevus of Ota is an uncommon dermal melanosis in the Indian subcontinent and is rarely associated with capillary malformations, classified as type II phakomatosis pigmentovascularis (PPV). It usually presents unilaterally as mottled, slate blue, or dark brown macules; bilateral presentation is only seen in a few cases. A 20-year female presented to Dermatology OPD of a tertiary hospital with bilateral nevus of Ota involving the cheeks, temples, nose, forehead, and sclera of the eyes for one year. She also had a port wine stain on the right arm, forearm, back, bittock, and thigh since birth without any other systemic involvement. We treated nevus of Ota with six sessions of 1064 nm picosecond laser every month at 0.8 J/cm2 with significant improvement in the appearance of the lesions and no adverse effects. This case highlights the importance of thoroughly examining pigmented lesions for additional cutaneous findings and the potential use of a 1064 nm picosecond laser to treat such lesions.
