Psoriasis is divided into three degrees of severity: mild, moderate and severe. Abou75 percent to 80 percent of people with psoriasis have what is considered mild disease, and about 20 percent to 25 percent have moderate to severe psoriasis. These categories are useful for selecting what treatments might be appropriate for individuals with psoriasis. The physical measure of severity is based on how much skin on the body is affected by psoriasis. As a general rule of thumb, the palm of the hand represents 1 percent of the body´s surface. Severity can also hinge on how psoriasis affects a person´s quality of life. If psoriasis covers only a small area yet is serious enough to be disabling—for example, bad psoriasis of the hands or feet—it could be considered a severe case of the disease.

  • Moderate Psoriasis

    Moderate PsoriasisModerate psoriasis is defined as affecting between 2 percent and 10 percent of the body´s surface. Psoriasis may appear on the arms, legs, torso, scalp and other areas. Appropriate therapies include topical treatments, phototherapy and oral medications, depending on the location and extent of the psoriasis and other individual factors.

  • Severe Psoriasis

    Severe PsoriasisPsoriasis covering more than 10 percent of the body is considered severe. Extensive areas of skin may be covered with psoriasis plaques or pustules, or widespread erythrodermic psoriasis (as shown in the photo to the left) can cause severe peeling of the skin.
