Abstract:
Progressive cribriform and zosteriform hyperpigmentation (PCZH) is a distinctive clinical entity first described by Rower et al. in 1978. It is characterized by a single area of uniformly tan cribriform macular pigmentation in a zosteriform distriggtjpp with no preceding history of skin rash, injury or inflammation. It begins well after birth with gradual extension and is not associatad with any other cutaneous or internal abnormalities. Histologically, there is a mild increase in melanin pigment in the basal cell layer and complete absence of nevus cells. Recently, we observed clinical and histological featurea of 5 cases of PCZH. The age at onset ranged from 4 to 35 years. The lesions were unilaterally distributed on face, neck, chest, or abdomen. Histologically there was a mild increase in melanin pigment in the basal cell layer. PCZH must be differentiated from Beckers hairy nevus which begins with a unilateral lesion of irregularly macular pigmentation but occasionally it may be multiple or bilateral. In early stage, overgrowth of hairs may be absent but after a few years it is usually present. PCZH is characterized by uniformly tan cribriform pigmentation in zosteriform distribution, which is unilateral and does not cross the midline of the body. Overgrowth of hairs is absent even after a few years. So the lesions of Beckers hairy nevus previously reported, which were unilateral and did not cross the midline of the body and did not show overgrowth of hairs even after a few years, must be called progressive cribriform and zosteriforrn hyperpigmentation.
