|Mortality and Prognosis
Psoriasis is an autoimmune skin disease that causes scaly red patches of skin. Sometimes people with psoriasis develop joint pain, which is called psoriatic arthritis.
If you develop a scaly red rash that doesn't go away in a reasonable period of time with the usual over-the-counter products, see your doctor as it may be psoriasis or another skin condition. (Also see Autoimmune Diseases and Skin Diseases)
