From ankylosis to pencil-in-cup deformity in psoriatic arthritis: a case report

Clin Exp Rheumatol. 2009 Jul-Aug;27(4):661-3.

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.
