Healthgrades

Psoriatic arthritis is an arthritis that is associated with psoriasis, a chronic skin and nail disease. Psoriasis is characterized by red, scaly rashes and thick, pitted fingernails. In terms of symptoms and joint swelling, psoriatic arthritis is similar to rheumatoid arthritis (RA) (inflammation). However, it affects fewer joints than RA. It also does not produce the typical RA antibodies. Psoriatic arthritis can be classified into five types: arthritis of the small joints in the fingers, toes, or both; symmetrical arthritis of the joints in the hands and feet; symmetrical polyarthritis, which is similar to RA; arthritis mutilans, a rare type of arthritis that destroys and deforms joints; and psoriatic spondylitis, arthritis of the lower back (sacroiliac sac) and the spine. Doctors are baffled as to what causes psoriatic arthritis. Immunity, genes, and the environment, however, may all play a role. Psoriasis symptoms can appear before or after arthritis. Psoriasis is characterized by red, scaly rashes and thick, pitted fingernails. Psoriatic arthritis can affect one in every 20 to one in every ten people who have psoriasis. Psoriatic arthritis symptoms include inflamed, swollen, and painful joints, particularly in the fingers and toes, as well as deformed joints caused by chronic inflammation. Psoriatic arthritis symptoms can mimic those of other medical conditions. Consult your healthcare provider for a diagnosis.
