What is psoriasis?
Psoriasis is a noncontagious skin condition that produces plaques of thickened, scaling skin. The dry flakes of skin scales are thought to result from the excessively rapid proliferation of skin cells triggered by inflammatory chemicals produced by specialized white blood cells called lymphocytes. Psoriasis commonly affects the skin of the elbows, knees, and scalp.
Some people have such mild, limited psoriasis that they may not even suspect that they have a medical skin condition. Others have very severe psoriasis that affects their entire body surface.
Psoriasis is considered an incurable, long-term (chronic) skin condition. It has a variable course, periodically improving and worsening. It is not unusual for psoriasis to spontaneously clear for years and stay in remission. Many people note a worsening of their symptoms in the colder winter months.
Psoriasis affects all races and both sexes. Although psoriasis can be seen in people of any age, from babies to seniors, most commonly patients are first diagnosed in their early adult years. The quality of life of patients with psoriasis is often diminished because of the appearance of their skin. Recently, it has become clear that people with psoriasis are more likely to have diabetes, high blood lipids, and heart disease. There are hypotheses as to how this might related to their overall ability to control inflammation. Caring for psoriasis takes medical teamwork.

As mentioned above, psoriasis appears as a small bump, a papule, surmounted by scale. When these papules combine, a plaque is formed that is covered by excessive layers of horny skin that is perceived as a silvery scale. This scale is shed and appears as dandruff.
