title: Plaque-type blue nevus on the face: a variant of Ota's nevus?
abstract: We describe a plaque-type blue nevus that had been present since birth on the right cheek of a 22-year-old man. It was characterized by several dark blue macules and papules with intervening areas of faint blue discoloration. Histologic examination showed a common blue nevus and a mongolian spot-like dermal melanocytosis in the dark blue and intervening faint blue pigmentary lesions, respectively.
