title: [Psoriatic arthritis--diagnostic criteria].
abstract: Arthritis psoriatica has been known for over 160 years, however, not long ago it became a separate nosologic unit. In 1964 American Rheumatological Society introduced the name arthritis psoriatica, which is obligatory nowadays. It was thought in the beginning that the inflammation may coexist with psoriasis accidentally only, whereas epidemiological studies, clinical observations and serologic data excluded such a simple relation. Since the international diagnostic criteria were established and also the rheumatoid factor was discovered it has been clear there's a direct relation between arthritis psoriatica and dermatologic changes of a psoriasis type. Therefore it is a disease where rheumatology and dermatology meet with each other. The aim of our study was to collect the knowledge about the diagnosis of arthritis psoriatica.
