Circumscribed psoriasis generally refers to circumscribed pustular psoriasis, which can be treated with topical medication or oral medication. 1. Topical medication: local treatment can use vitamin A acid drugs and vitamin D3 derivatives, such as tazarotene gel, carbotriol, tacalcitol and so on. Glucocorticoid drugs can be used during acute attacks, such as mometasone furoate cream, tretinoin cream and so on. 2. Oral drugs: you can take methotrexate, cyclosporine and other immunosuppressants to promote the recovery of the disease, in addition to the use of retinoic acid drugs, such as Avicenna and other drugs to regulate the epidermal keratinization and differentiation and proliferation, to promote the inflammation to subside. Due to the different degree of illness, personal constitution is not the same, so the diagnosis of annular pustular psoriasis should strictly follow the doctor’s instructions for treatment, not indiscriminate use of drugs.
