Abstract: 【Abstract】 In the past, psoriasis was considered as a non-pruritic skin disease. In recent years, it has been gradually realized that pruritus is one of the factors that aggravate the disease burden of patients with psoriasis. This review mainly elaborates epidemiologic and clinical characteristics of pruritus in psoriasis, focuses on the role of abnormal expression of neuropeptides and abnormal distribution of nerve endings in neurogenic inflammation in the pathogenesis of pruritus, and introduces the effect of treatment of psoriasis on the relief of pruritus.

Key words: Psoriasis, Pruritus, Neurogenic inflammation, Neuropeptides
