General Discussion

Psoriasis is a chronic, inflammatory skin disease characterized by dry, reddish (erythematous), thickened patches of skin that are covered with silvery-gray scales. These patches may be referred to as papules or plaques and most often affect the scalp, elbows, knees, hands, feet and/or lower back. The plaques may be intensely itchy (pruritis) or sore. In some cases, individuals with psoriasis may experience abnormalities affecting the fingernails, toenails, and the soft tissues inside the mouth. The severity of psoriasis varies from case to case. Psoriasis may be classified as mild, moderate or severe depending upon the amount of skin involved and the effect on an individual's quality of life. In approximately one-third of cases a family history of psoriasis is present.
