Psoriatic arthritis (PsA) is an inflammatory arthropathy associated with psoriasis, which is classified within the group of spondyloarthritis. With the exception of the distal interphalangeal joints (hands and feet), there are no predictable joints for involvement in PsA, and the signs of inflammation are often more difficult to detect than those associated with rheumatoid arthritis. PsA is common in patients with psoriasis, and there is some evidence to suggest that the severity of psoriasis is associated with an increased risk for – although not greater severity of – PsA.
