Doctor's Notes on Plaque Psoriasis
Plaque psoriasis is a systemic disease of the skin that produces plaques (elevated skin abnormalities). Signs and symptoms start out as small scaly red bumps that come together and form elevated skin areas (plaques) with a pinkish-reddish base and scaly skin that may be a whitish color. The plaques are often itchy. Although any skin area may be involved, it occurs most often in patches on the elbows, knees, and scalp.
The exact cause is unknown. The disease is thought to be the result of genetics and environmental problems that allow some factor to trigger the disease.
What Are the Treatments of Plaque Psoriasis?
Treatments of plaque psoriasis may include one or more of the following with examples:
- Topical skin medications
- Light therapy: ultraviolet light to treat skin plaques
- Systemic drugs (oral or IV drugs)
- Biologic drugs
You and your doctors can design treatments that best fit to treat your disease.

PsoriasisPsoriasis is a common and chronic skin disorder caused by inflammation that affects 1%-2% of people in the U.S. There are several different types of psoriasis.

Symptoms and signs include red, raised, scaly areas on the skin that may itch or burn. Treatment may involve topical therapy, phototherapy, and medication.
Psoriasis MedicationsThere are a number of good treatment options to control the skin lesions of psoriasis. Topical agents are practical when treating localized disease. Phototherapy should be considered if the disease covers more than 5%-10% of the total body surface area. Systemic agents should be started only after both topical treatment and phototherapy have been carefully considered.

Some psoriatic arthritis symptoms and signs include scaly red skin on certain areas of the body, nail changes, eye inflammation, iritis, and inflammation of the muscles and tendons where they connect to the bone.
