Nevus of Ota is a type of dermal melanocytosis, it is distributed along the ophthalmic and maxillary divisions of the trigeminal nerve and presents as a blue or gray patch on the face [1]. In the opposite, vitiligo is a benign disorder,secondary to chronic degradation of melanocytes in epidermis and follicles, characterized by depigmented lesions [2]. Nevus of Ota is a rare disorder, and the appearance of vitiligo lesions withassociated to nevus of Ota is exceptional. Herein, we report a new case of a teenager with this association [3].

A 16-year-old female presented in our clinical with hypochromic lesions on the face4 monthsearlier. A history of bluish patches which had been present since birth was reported. Physical examination showed white macula on the posterior part of cheek, poorly bounded with irregular contours, with better evidence under Wood’s lamp (Figs. 1a and 1b). We described as well a blue-grayish macula on the dermatome of maxillary divisions of the trigeminal nerve, adjacent to the previous lesion, which dermoscopy revealed blue-grayish structures with iridescent reflections (Figs. 2a and 2b).
