Psoriasis is a chronic skin condition that causes itchy, scaly patches on the skin, most commonly on the knees, elbows, trunk, and scalp. While there is no cure for psoriasis, treatments are available to help manage symptoms. Topical corticosteroids are the most frequently prescribed medications for treating mild to moderate psoriasis. Other treatments include vitamin D analogues, calcineurin inhibitors, coal tar, and dithranol.

For more severe cases, systemic treatments such as methotrexate, cyclosporine, or biologic therapy may be necessary. Phototherapy is also a first-line treatment for moderate to severe psoriasis. Lifestyle habits and coping strategies can also help manage symptoms.

Psoriasis usually indicates the presence of other diseases including cardiovascular disease and malignancy.
