What is Psoriasis?
Psoriasis is a common and chronic incurable but treatable skin disorder. Plaque psoriasis is the most common form and appears as elevated plaques of red skin covered with silvery scale that may itch or burn. The involved areas are usually found on the arms, legs, trunk, or scalp but may be found on any part of the skin. The most typical areas are the knees, elbows, and lower back.

Psoriasis is not contagious but can be inherited. Research indicates that the disease may result from a disorder in the immune system.
A significant percentage of people with plaque psoriasis also have psoriatic arthritis. Individuals with psoriatic arthritis have inflammation in their joints and may have other arthritic symptoms. Sometimes plaque psoriasis can evolve into more inflammatory disease, such as pustular psoriasis or erythrodermic psoriasis.

Psoriasis affects children and adults. Men and woman are affected equally.
Psoriasis can affect all races. Studies have shown that more people in western European and Scandinavian populations have psoriasis than those in other population groups.
