Other studies

  • Radiographs of affected joints: Can be helpful in differentiating types of arthritis

  • Joint radiographs: Can facilitate the diagnosis of psoriatic arthritis

  • Bone scans: Can identify joint involvement early

  • Dermatologic biopsy: Can be used to make the diagnosis when some cases of psoriasis are difficult to recognize (eg, pustular forms)

See Workup for more detail.
