Psoriasis vulgaris: The medical name for the most common form of psoriasis (“vulgaris” means common). About 80% of people with psoriasis have this type. It is also called plaque psoriasis because of the characteristic plaques on the skin: well-defined plaques of red raised skin that can appear on any area of skin, although the knees, elbows, scalp and trunk are the most common locations. The flaky silvery white buildup on top of the plaques is called scale; it is composed of dead skin cells. This scale comes loose and sheds constantly from the plaques. Skin symptoms include pain, itching and cracking.
Psoriasis is a long-term skin condition that may cause large plaques of red, raised skin, flakes of dry skin, and skin scales. There are several types of psoriasis, including psoriasis vulgaris, guttate psoriasis, inverse psoriasis, and pustular psoriasis. Depending on the type of psoriasis the individual has symptoms vary. Treatment of psoriasis may include creams, lotions, oral medications, injections and infusions of biologics, and light therapy.
There is no cure for psoriasis. The goal of treatment is to control symptoms and prevent infection.
