Dermal Melanocytoses

  • Guido Massi

Dermal melanocytoses are peculiar melanocytic lesions characterized by a bluish discoloration of large portions of the skin. The different clinical entities are situated in specific areas of the body. Histologically speaking, all the lesions consist of a sparse melanocytic infiltrate among undisturbed collagen fibers. Melanocytes are elongated with thin, pigmented cytoplasmatic dendrites. This group of lesions may be a variation on the theme of blue nevus.
