Sarcoid dactylitis.

Dactylitis is a rare rheumatological complication of sarcoidosis. It may be accompanied by underlying bone changes, and management is often difficult. We report these 4 cases of dactylitis in which there have been significant bone changes and associated management problems. One case is further complicated by biopsy-proved sarcoid synovitis, uncommon in a British resident, and 2 cases show destructive bone changes, which have rarely been reported in sarcoidosis.
