Brief description
Psoriatic arthritis is a chronic inflammatory arthritis resembling rheumatoid arthritis. It occurs in up to 30% of people with psoriasis, but may also occur in the absence of psoriasis. In a person with an inflammatory arthritis and psoriasis the diagnosis of psoriatic arthropathy needs to be considered, but is not automatic.
Confirming the diagnosis
There are no specific diagnostic tests and a range of clinical presentations. Diagnosis typically requires specialist opinion and is normally made on clinical grounds together with appropriate laboratory testing and imaging.
The appropriate medical specialist is a rheumatologist.
