Abstract:
Progressive cribriform and zosteriform hyperpigmentation(PCZH) is a pigmentary disorder of the skin which is a distinctive clinical entity first described by Rower et al. in 1978. It is characterized clinically by a single area of uniformly tan cribriform macular pigmentation in a zosteriform distribution without preceding history of skin rash, injury or inflammation and histopathologically by a mild increase of melanin pigment in the basal cell layer and complete absence of nevus cells. We report herein three cases of PCZH. The age at onset ranged from 30 to 39 years. The lesions were unilateraly distributed. The lesions of two cases were on left lower extremity and the lesions of another case were on right flank and right thigh. Histopathologic examination of the lesions showed a mild increase in melanin pigment in the basal cell layer with absence of nevus cells.
