Psoriatic arthritis is a specific condition in which a person has both psoriasis and arthritis. Psoriatic arthritis is an autoimmune disease, meaning that the immune system is misdirected to cause inflammation of one's own tissues. Rarely, a person can have psoriatic arthritis without having skin psoriasis. Moreover, the arthritis can precede the psoriasis by months or years, or present after years of psoriasis.
