title: [Sarcoid synovitis. A case report of localization at the level of the flexor tendons of the fingers].
abstract: Sarcoidosis without bone involvement or sarcoid dactylitis, is a very unusual cause of flexor synovitis. Our reported patient initially presented with chronic arthralgia of the knees and ankles. The initial diagnosis of rheumatoid arthritis was incorrect. A surgical flexor synovectomy was performed to release painful compression of the median nerve due to the synovitis. The correct diagnosis was suggested by the histopathological examination showing noncaseating epithelioid granulomas. The diagnosis was confirmed by the association of a negative tuberculin test and raised angiotensin converting enzyme. No recurrence of synovitis occurred after surgical excision and colchicine therapy but arthralgia persisted.
