Abstract: 【Abstract】 Psoriasis is an immune-mediated chronic, recurrent, inflammatory, systemic disease induced by the interaction between the individual and environment. Psoriasis is a non-communicable disease, its typical clinical manifestations are locally or widely distributed scaly erythema or plaques. The etiology of psoriasis involves heredity, immunity, environment, and other factors. Until now, psoriasis is still an incurable disease. Choosing appropriate drugs and regimens is very important for patients with psoriasis to control the condition, reduce comorbidities, maintain long-term efficacy, and comprehensively improve the quality of life. To standardize the diagnosis and treatment procedure of psoriasis, improve treatment effectiveness, and minimize adverse reactions, the Committee on Psoriasis of Chinese Society of Dermatology formulated this guideline based on the "Guideline for the diagnosis and treatment of psoriasis in China （2018 complete edition）" and according to the current situation in China, with some contents supplemented and revised in this guideline. Because latest research achievements in traditional Chinese medicine for the diagnosis and treatment of psoriasis were combined, this guideline was also an integrated Chinese and Western medicine guideline for the diagnosis and treatment of psoriasis. Considering the complexity of psoriasis, the treatment regimens should be decided according to patients′ individual situation. Topical treatment is commonly recommended for patients with mild psoriasis, systemic treatment can be chosen for those with moderate to severe psoriasis, and biological agents or small-molecule drugs can be selected for those with poor response to traditional systemic treatment.
