Abstract:
Pruritus is a common symptom of most primary skin diseases and some systemic diseases. Despite the high incidence of pruritus in patients with psoriasis,the specific pathogenesis is complex and unclear. The occurrence and development of skin pruritus in psoriasis patients involve the joint participation of nervous,immune,endocrine,and vascular systems.This article reviews the mediators related to the pathogenesis of pruritus in psoriasis,aiming to improve the understanding of itching symptoms and the treatment of pruritus.

Papillary Dermis
The dermis might be considered the "core" of the integumentary system, as distinct from the epidermis and hypodermis. It contains blood and lymph vessels, nerves, and other structures, such as hair follicles and sweat glands. The dermis is made of two layers of connective tissue that comprise an interconnected mesh of elastin and collagenous fibers, produced by fibroblasts.
