Summary
Progressive cribriform and zosteriform hyperpigmentation (PCZH), first described by Rower et al in 1978, is a distinctive clinicopathological pigmentary disorder of the skin [1]. PCZH refers to an asymptomatic dermatosis consisting of a single area of uniformly tan, cribriform, macular pigmentation in a zosteriform distribution; histological pattern consisting of mild increase in melanin pigment in basal cell layer and complete absence of nevus cells. Di Lernia et al [2], suggested that PCHZ should be considered as a part of spectrum of Linear and Whorled Nevoid Hyperpigmentation(LWNH) as apart from later age of onset, there was no difference between the two disorders clinically and histopathologically.
