The role of the dermatologist in identification and treatment of the early stages of psoriatic arthritis.

Early diagnosis of psoriatic arthritis (PsA) is essential for preventing disease progression and joint destruction. The majority of patients develop PsA years after the onset of their skin disease. Therefore, dermatologists are in a strategic position to make the diagnosis of PsA, and either manage it or refer the patient to a rheumatologist in order to prevent the potentially irreversible destruction of the affected joints. We will review the presentation and temporal relationship of psoriasis and PsA, the diagnosis, classification, and management, in addition to the role of the dermatologist in the early detection of PsA.
