AbstractTHE CONTEXT: Psoriasic arthritis lies somewhere between rhumatoid polyarthritis and spondyloathropathy. Its prevalence is about 0.1% with a 1/1 sex ratio. Mean age at onset of symptoms is 40 years. In 10 to 15% of the cases, rhumatological manifestations are observed before skin lesions. Ungueal involvement is particularly frequent. FIVE CLINICAL FORMS: Classically, five clinical forms are described: arthritis limited to the distal interphalangeal joints, mutilating arthritis, symmetrical polyarthritis, asymmetrical mono- or oligoarthritis, and spondylitis. Asymmetrical oligoarticular forms and polyarithrtis predominate. DISEASE SEVERITY: In general psoriasic arthritis is a benign condition. Severe forms have however been described with erosion and osteolysis involving the distal interphalangeal joints. Typical radiological may be observed.
