Psoriatic arthritis (also arthritis psoriatica arthropathic psoriasis or psoriatic arthropathy) is a type of inflammatory arthritis that will develop in up to 30 percent of people who have the chronic skin condition psoriasis. Psoriatic arthritis is said to be a seronegative spondyloarthropathy and therefore occurs more commonly in patients with tissue type HLA-B27.
