Psoriatic arthritis is a chronic inflammatory arthropathy associated with cutaneous psoriasis.
It is a progressive disease with asymmetric joint distribution pattern and rheumatoid factor is negative.
It can develop at any time including childhood but most often occurs between 30-50 years old.
Symptoms may range from mild to very severe.
