Psoriatic arthritis (PsA) is an inflammatory arthritis that occurs in patients with psoriasis, a chronic skin condition present in 2-3% of the general population. It is not as well-recognized as other forms of arthritis, such as rheumatoid arthritis (RA) or osteoarthritis (OA), and is likely underdiagnosed.
