Michael Roizen, MD, Internal Medicine, answeredPlaque psoriasis is the most common type of psoriasis. About 80% of people with psoriasis have it. This type of psoriasis usually occurs on the places you hear old relatives complain about the most: knees, elbows, lower back, and head (scalp). You can identify it by the characteristic raised, red patches of skin with white or silver patches of dead skin on top that flake off. It may feel as itchy as the old, wool costume you had to wear for your school play.

Psoriasis is a skin disease that affects the normal growth of skin cells. It causes cells to form rapidly on the skin's surface, creating thick scaly patches. Plaque psoriasis is the most common form. Lesions (plaques) can form anywhere on the body and can be itchy or painful. Plaques consist of dry, raised skin that is usually red with silvery scales. Severity varies. Some may have only a small number of plaques. In more severe cases, skin surrounding the joints can crack and bleed.

The most common type of psoriasis is plaque psoriasis. According to the National Institutes of Health, about 7.5 million people in the US have psoriasis. It's estimated that about 80 percent of people with psoriasis have plaque psoriasis.
With plaque psoriasis, you will have itchy, irritated and raised, red skin lesions covered with a silvery white scale. While psoriasis can occur anywhere on the body, plaque psoriasis is usually found on the lower back, elbows, scalp, and knees.
Each type of psoriasis has it's own unique characteristics and symptoms. Usually a person will only have one type of psoriasis. Or sometimes, one type of psoriasis will clear up only for another type to appear.
Mark Morocco, Emergency Medicine, answeredPsoriasis is a chronic immune system disease of the skin that occurs when skin cells grow too quickly. Faulty signals in the immune system cause new skin cells to form in days rather than weeks. The body does not shed these excess skin cells, so the cells pile up on the surface of the skin and lesions form. Plaque psoriasis (psoriasis vulgaris) is the most prevalent form of the disease. About 80 percent of those who have psoriasis have this type. It is characterized by raised, inflamed, red lesions covered by silvery-white scales. It is typically found on the elbows, knees, scalp, and lower back.
