Cutis tricolor.

Cutis tricolor is characterized by the coexistence of congenital hyperpigmented and hypopigmented patches in the context of normally pigmented skin. We report the case of a 13-year-old white adolescent girl with cutis tricolor. We analyze other reported cases of cutis tricolor as well as other cases characterized by coexistent hyperpigmented and hypopigmented patches. Cutis tricolor seems to be a rather unique cutaneous manifestation and occurs either in isolation or in association with internal manifestations. Labeling any other case characterized by hyperpigmented and hypopigmented patches as cutis tricolor, regardless of the distribution pattern, is inappropriate in our opinion.
