Plaque psoriasis is a very common form of psoriasis where the skin becomes red, flaky and develops silver colored scales. This type of psoriasis affects approximately 2 to 3 % of the population. It generally comes on between the ages of 15 and 25. It is caused by a disruption in the immune system and there is no cure for the condition.
The skin grows quickly around the outer area of the joints. (See Figure 1) The knees, elbows palms, genitals and scalp are most often affected. Plaque psoriasis can also cause a type of arthritis in 10 to 30% of psoriasis patients. It will last the lifetime of the patient and re-occurs even with aggressive treatment. The disease does tend to “flare” at times and get better during periods of less stress and illness.
