Scripture: Deuteronomy 24:8 New Revised Standard Version (NRSV) Guard against an outbreak of a leprous[a] skin disease by being very careful; you shall carefully observe whatever the levitical priests instruct you, just as I have commanded them.


Psoriasis is an autoimmune disease that causes raised, red, scaly patches to appear on the skin. It typically affects the outside of the elbows, knees or scalp, though it can appear on any location. Some people report that psoriasis is itchy, burns and stings. Psoriasis is associated with other serious health conditions, such as diabetes, heart disease and depression.

Usually, something triggers psoriasis to flare. The skin cells in people with psoriasis grow at an abnormally fast rate, which causes the buildup of psoriasis lesions. Psoriasis is not contagious. It is not something you can “catch” or that others can catch from you. Psoriasis lesions are not infectious.

There are five types of psoriasis.

Plaque Psoriasis is the most common form of the disease and appears as raised, red patches covered with a silvery white buildup of dead skin cells or scale. These patches or plaques most often appear on the scalp, knees, elbows and lower back. They are often itchy and painful, and they can crack and bleed.

Guttate Psoriasis [GUH-tate], the second most common type of psoriasis often starts in childhood or young adulthood. This is psoriasis, after plaque psoriasis. This form of psoriasis appears as small, red, separate spots on the skin. Guttate lesions usually appear on the trunk and limbs and can number in the hundreds. Sometimes lesions form on the scalp, face and ears. This form can precede or co-exist with other forms of psoriasis, such as plaque.Guttate psoriasis comes on quite suddenly from a variety of known triggers, including:Upper respiratory infections, streptococcal infections,tonsillitis, stress, Injury to the skin and drugs. Strepthroat is a common guttate psoriasis trigger.

Inverse Psoriasis (also known as intertriginous psoriasis) shows up as very red lesions in body folds. It may appear smooth and shiny. Many people have another type of psoriasis elsewhere on the body at the same time. Inverse psoriasis is found in the armpits, groin, under the breasts and in other skin folds on the body.It is particularly subject to irritation from rubbing and sweating because of its location in skin folds and tender areas. It is more common in overweight people and people with deep skin folds.

Pustular Psoriasis [PUHS-choo-lar] is characterized by white pustules (blisters of noninfectious pus) surrounded by red skin. The pus consists of white blood cells. It is not an infection, nor is it contagious. Pustular psoriasis is primarily seen in adults. It may be limited to certain areas of the body — for example, the hands and feet. Generalized pustular psoriasis also can cover most of the body. It tends to go in a cycle with reddening of the skin followed by pustules and scaling.


  • Topical Treatments with and without steroids usually are the first choice in treating psoriasis. Prescription topicals slow down skin cell growth and reduce inflammation.
  • Phototherapy exposes the skin to ultraviolet light on a regular basis and under medical supervision.
  • Systemic medications are prescription drugs that work throughout the body. They are used for individuals with psoriatic arthritis and those with moderate to severe psoriasis whose symptoms are unresponsive to other treatments.
