Psoriasis is a chronic inflammatory disease of the skin. It is a skin disorder characterized by epidermal hyper proliferation and dermal inflammation that differ in severity, from small, confined patches to complete body coverage. It affects approximately 2–3 percent of the population, making it one of the most prevalent autoimmune diseases worldwide. In this disease skin cells replicate at an exceptionally rapid rate, about eight times faster than the normal skin cells. This results in the build-up of cells on the skin's surface forming thick patches or plaques. It is a lifelong skin disease that begins in the immune system, mainly with a type of white blood cell called a T-cell. T-cells help protect the body against infection and disease. In psoriasis, T-cells are set into action by error and they turn out to be so active that they start out other immune responses. This results into swelling and quick turnover of skin cells. There is no cure for psoriasis. But numerous topical, systemic, and biologic therapies are available for the treatment of mild psoriasis or controlling the severe psoriasis. Treatment modalities are chosen on the basis of disease severity, cost, efficacy, patient preference, and evaluation of individual patient response.
