Poliosis is a localized loss of hair pigment.1 It has been previously associated with intradermal nevi, halo nevi, melanoma of the scalp, and genetically based syndromes such as piebaldism, Wardenburg syndrome, and tuberous sclerosis.1- 4 We present a case in which diffuse segmental poliosis developed on a giant congenital nevus. This association has not been previously reported.
