A.

No. There are considered to be five different forms of psoriatic arthritis:

  • Symmetric: Affects multiple symmetric pairs of joints (occurs in the same joints on both sides of the body).
  • Oligoarticular: Affects few joints in an asymmetric pattern and is usually milder.
  • Distal interphalangeal (DIP): Affects primarily the distal joints of the fingers and toes (the joints closest to the nail).
  • Spondylitis: Predominantly affects the spinal column from the neck to the lower back.
  • Arthritis mutilans: Affects the small joints of the hands and feet, although it can appear in other joints. This rare form of arthritis is severe and destructive.
