Psoriasis is a most comman disease related to skin.Psoriasis is a chronic , non-contagious autoimmune disease which affects the skin and joints. It causes red scaly patches to appear on the skin. The scaly patches caused by psoriasis , called psoriatic patch,are areas of inflammation and excessive skin production.that gives silvery white appearance.
Psoriasis is quite common , affecting around two per cent of the population, although people with very mild symptoms may not be aware they have it. Psoriasis can begin at any age but usually starts either around the age of 20 or between 50 and 60.
The disorder is a chronic recurring condition which varies in severity from minor localized patches to complete body coverage. Fingernails and toenails are frequently affected (psoriatic nail dystrophy) and can be seen as an isolated finding. Psoriasis can also cause inflammation of the joints, which is known as psoriatic arthritis. In contrast to eczema, psoriasis is more likely to be found on the extensor aspect of the joint.
The cause of the psoriasis is still unclear.
