Abstract:
A 56-year-old woman with psoriatic arthritis is presented whose initially ankylosed digit was later found to develop pencil-in-cup change. The patient was treated over that period with etanercept and had no signs of active arthritis. The possible mechanisms for these changes are discussed.
