title: Diagnostic signs and symptoms of psoriatic arthritis.
abstract: PsA is a distinct pathologic entity with a unique set of diagnostically relevant clinical features. The typical clinical picture of PsA consists of peripheral joint inflammation with an asymmetric pattern of involvement. Furthermore, other clinical signs, such as sacroiliitis, enthesitis, dactylitis, and nail lesions, are also closely associated with the disease. By gaining familiarity with the features of PsA, as well as the ways in which disease presentation may vary, health care professionals will be better equipped to identify this condition, making early treatment, which is an essential step toward optimizing patient outcomes, more readily achievable.
