Abstract

Psoriatic arthritis is an inflammatory musculoskeletal disease affecting almost a third of patients with psoriasis. Clinical presentations are complex and varied and include peripheral arthritis, axial disease, dactylitis, and enthesitis, as well as skin and nail manifestations. We lack diagnostic biomarkers, but specific clinical and imaging features distinguish psoriatic arthritis from other forms of arthritis such as rheumatoid arthritis, gout, osteoarthritis, and other forms of spondyloarthritis.
