Psoriatic arthritis is a painful, disabling disease which involves inflammation of the skin and joints.

Psoriatic arthritis is characterized by synovitis and enthesitis. Synovitis is inflammation of the membrane that covers synovial joints. Enthesitis is inflammation of the entheses, which are the regions where tendons or ligaments attach to the bone.
