Psoriasis--is an immune-mediated disease that affects the skin. It is typically a lifelong condition. There is currently no cure, but various treatments can help to control the symptoms.
Psoriasis occurs when the immune system mistakes a normal skin cell f or a pathogen, and sends out faulty signals that cause overproduction of new skin cells. It is not contagious. Psoriasis has been linked to an increased risk of stroke, and treating high blood lipid levels may lead to improvement. There are five types of psoriasis: plaque, gutate, inverse, pustular, and erythrodermic. The most common form, plaque psoriasis, is commonly seen as red and white hues of scaly patches appearing on the top first layer of the epidermis (skin). Some patients, though, have no dermatological signs or symptoms. The name psoriasis is from the Greek language, meaning roughly "itching condition" (psora "itch" + -sis "action, condition").
In plaque psoriasis, skin rapidly accumulates at these sites, which gives it a silvery-white appearance.
Plaques frequently occur on the skin of the elbows and knees, but can affect any area, including the scalp, palms of hands and soles of feet, and genitals. In contrast to eczema, psoriasis is more likely to be found on the outer side of the joint.
The disorder is a chronic recurring condition that varies in severity from minor localized patches to complete body coverage. Fingernails and toenails are frequently affected (psoriatic nail dystrophy) and can be seen as an isolated sign. Psoriasis can also cause inflammation of the joints, which is known as psoriatic arthritis. Between 10% and 30% of all people with psoriasis also have psoriatic arthritis.
