Abstract 

Psoriasis is a chronic, inflammatory and hyperproliferative skin disease with a genetic basis. While epidermal hyperplasia and altered keratinocyte differentiation are prominent features, considerable evidence indicates that psoriasis is immunologically mediated. Recently, the identification of HLA-Cw6 as the disease allele conferring susceptibility to psoriasis has provided a focus for elucidation of these events. In this article, we will focus on the epidemiology of psoriasis and its associated arthritis.
