Psoriatic arthropathy: where now?

P soriatic arthropathy is a common inflammatory arthritis that characteristically occurs in individuals with psoriasis [1]. PsA was classified as a distinct entity for the first time in 1964 [2], but the antiquity of this disease can be dated back tens of centuries [3]. The many faces of PsA have historically complicated the timely diagnosis on the one hand, while its aggressive and destructive behavior has been recently recognized in up to 20% of affected persons on the other [4]. As such, PsA has attracted much attention lately, resulting in tremendous progress in the understanding, classification and treatment of the disease in recent years. This review will summarize the current experience in PsA in light of the recent developments in the field.
