Abstract
Psoriatic arthritis is the most common extra-cutaneous manifestation of psoriasis, and affects
musculoskeletal structures mainly joints and entheses, where tendons and ligaments attach to the bone. It is a
chronic immune-mediated, seronegative arthritis with a heterogeneous presentation. Its prevalence ranges from
3.2 to 41% among psoriatic patients with equal sex prevalence. Most of the PsA patients were first evaluated for
skin psoriasis 10 years before PsA onset and PsA is often undiagnosed and unrecognized among patients
followed at dermatology clinics. So, we have to equip dermatologists with tools that can easily assist in
identifying PsA.
The psoriasis epidemiologic screening tool (PEST) is a validated screening tool for psoriatic arthritis (PsA) that
was developed to detect and study the prevalence of PsA. Since it has only five questions, it is easy to use in
routine OPD setup.
