title: The classification of psoriatic arthritis: what will happen in the future?
abstract: Some patients with psoriasis have articular involvement that falls within the spectrum of seronegative spondyloarthropathies. This form of arthritis has been classified by Moll and Wright into five clinical subsets. Recently this classification has been contested. We review the historical evolution of the concept of psoriatic arthritis and discuss its clinical spectrum.
