FERNANDEZ AVILA, Daniel G et al. Diagnosis of Psoriatic Arthritis. []. , 16, 4, pp.342-351. ISSN 0121-8123.

Psoriatic arthritis is a relatively recent description disease in the rheumatology field. Previously physicians considered that the patient with psoriasis and any type of arthropathy had two diseases that coincided at the time: psoriasis and rheumatoid arthritis. There have been many attempts to classify these patients adequately. In the last 36 years seven criteria for the classification of this entity have appeared. In this article we made a summary of the clinical characteristics, laboratories and imaging in psoriatic arthritis. Furthermore, we intend to describe the classification criteria in chronological order.

: psoriasis; psoriatic arthritis; arthritis; dactyilitis.
