摘要

Nevus of Ota or nevus fusco-caeruleus ophthalmomaxillaris is a dermal melanocytic nevus is characterized clinically by blue gray patches and macules along the first and second branches of trigeminal nerve [1]. Here we report the case of a patient with new dermoscopic findings. A 22-year-old female presented with asymptomatic pigmented lesions on the first dermatome of trigeminal nerve since the age of 10 years. Clinical examination revealed a bluish hyperpigmented patch involving forehead, periorbiteal area and temple (Fig. 1). No pigmentation was found in the sclera of homolateral eye ni Ito nevus was found. Dermoscopy showed blue-grayish structureless with iridescent reflections and white rosettes in many places (Figs. 2a and 2b). Hence, a diagnosis of nevus of Ota was formulated.
