Abstract
|
|
|
|
Progressive cribriform and zosteriform hyperpigmentation (PCZH) is a distinctive pigmentary disorder observed along the lines of Blaschko. Clinically, the lesions appear as uniformly tan, cribriform macular hyperpigmentation with a zosteriform distribution, without a history of rash, injury, inflammation, or other associated cutaneous or internal abnormalities. Histopathological specimens show increased melanin pigmentation in the basal cell layer with a complete absence of nevus cells. We report 8 cases of PCZH and review the literature on this peculiar disorder
