Psoriatic arthritis is an inflammatory seronegative spondyloarthropathy that occurs in approximately 25% of patients with psoriasis and is a progressive and severely disabling disease. Most patients have had psoriasis for several years before the development of arthritis or develop the joint and skin condition simultaneously. Given the absence of specific diagnostic test for psoriatic arthritis, clinical findings remain the standard criteria for the diagnosis. Patients with psoriasis presenting to the dermatologist for management of their skin disease may have joint symptoms related or not to psoriatic arthritis and similarly arthritic patients presenting to a rheumatologist for the management of psoriatic arthritis may have skin lesions related or not to psoriasis. In this paper an expert panel of specialist belonging to the Associazione Dermatologi Ospedalieri Italiani (ADOI) and Collegio dei Reumatologi Ospedalieri Italiani (CROI) analysed the international literature and scientific recommendations and also investigated the Italian setting. It has been demonstrated in the literature that a multidisciplinary clinical setting may benefit patients with psoriatic arthritis from both diagnostic and therapeutic points of view. The comparative analysis of the Italian clinical records used by ADOI and CROI have highlighted some substantial differences. Collaboration between the dermatologist and rheumatologist allows for a more complete appreciation of the overall skin and musculoskeletal disease burden, and subsequently leads to a more comprehensive treatment approach.
