Abstract

Progressive cribriform and zosteriform hyperpigmentation (PCZH) was first described in 1978 by Rower and his colleagues as having the following clinical characteristics: a single area of uniformly-tan, cribriform, macular pigmentation in a zosteriform distribution, an histologically mild increase of melanin pigment in the basal cell layer and complete absence of nevus cells, no preceding history of skin rash, injury or inflammation, onset after birth with gradual extension - age at onset was in the second decade of life, lack of other associated cutaneous or internal abnormalities. We hereby report an atypical case of PCZH in a 16-year-old boy, who presented with multiple, cribriform and zosteriform hyperpigmented lines on his right arm and leg. This is the first ever reported case which has an association with Becker's nevus and melanonychia.
