Vanishing finger in psoriatic arthritis: a case report.
Dactylitis is a typical phenomenon in psoriatic arthritis, presenting as a "sausage-shaped" finger. Although classically the distal interphalangeal joints are affected, proximal interphalangeal joints and metacarpophalangeal joints are frequently involved. We present a patient who presented with severe psoriatic arthritis of the proximal interphalangeal joint, leading to subtotal disappearance of the phalangeal bones and important shortening of the fourth finger after 10 years of evolution.
