Psoriasis
Introduction
In the United States, psoriasis affects approximately two percent of the population and there are 150,000 new cases each year. It is a chronic skin condition that can occur over a large percentage of the body, but it is usually found on very characteristic sites such as the elbows, knees, nails and scalp. Although psoriasis is very common in some families, it is not a contagious disease; it cannot be passed from one person to another. The skin lesions are generally described as red or erythematous plaques with thick white scale. With a classic presentation the diagnosis of psoriasis is seldom missed. However, certain individuals have non-classic presentations, and they may go undiagnosed for years before being seen by a dermatologist. Even to the trained dermatologist, a skin biopsy is sometimes needed to confirm the diagnosis. Once psoriasis is diagnosed, therapy may be as simple as a topical steroid cream once or twice a day. Other times a more advanced regimen may be required. Therapy is often customized to the individual. With a growing number of treatment options, the patient with moderate to severe psoriasis may choose to seek the care of a board-certified dermatologist.
