Psoriasis
Psoriasis is a skin disease that causes itchy or sore patches of thick, red skin with silvery scales. You usually get the patches on your elbows, knees, scalp, back, face, palms and feet, but they can show up on other parts of your body. Some people who have psoriasis also get a form of arthritis called psoriatic arthritis.
Psoriasis
Erythematous, well-defined, dry, scaly papules and plaques of varying size, of salmon color.
Psoriasis is a chronic, noncontagious autoimmune disease that causes the skin to become inflamed and develop thick, scaly patches.
Causes of psoriasis
A problem with your immune system causes psoriasis. In a process called cell turnover, skin cells that grow deep in your skin rise to the surface. Normally, this takes a month. In psoriasis, it happens in just days because your cells rise too fast.
Psoriasis is thought to be caused by an overactive immune system that mistakenly attacks healthy skin cells. The exact cause isn’t fully understood, but it’s believed to be a combination of genetics and environmental factors.
Common triggers of Psoriasis
Stress
Skin injuries, such as cuts or sunburns
Infections, such as strep throat
Some medications, including lithium, prednisone, and hydroxychloroquine
Weather, especially cold, dry weather
Tobacco
Alcohol (heavy drinking)
