A multidisciplinary approach to giant cell tumors of tendon sheath and synovium—A critical appraisal of literature and treatment proposal



Giant cell tumors deriving from synovium are classified into a localized (GCT of tendon sheath; GCT-TS) and diffuse form (diffuse-type GCT, Dt-GCT). We propose a multidisciplinary management based upon a systematic review and authors' opinion. Open excision for GCT-TS and open synovectomy (plus excision) for Dt-GCT is advised to reduce the relatively high recurrence risk. External beam radiotherapy should be considered in severe cases, as Dt-GCT commonly extends extra-articular. J. Surg. Oncol. 2013;107:433–445. © 2012 Wiley Periodicals, Inc.
