Giant cell tumor of the tendon sheath (nodular

Giant cell tumor of tendon sheath or synovium (nodular tenosynovitis) is a common tumor that may present as either localized or diffuse disease. Other diagnostic terms used for this lesion include nodular or diffuse pigmented villonodular tenosynovitis, xanthogranuloma, benign synovioma, and fibrous histiocytoma of tendon sheath or synovium Background: Tenosynovial giant cell tumor (TSGCT) originates from the synovial cells of the tendon sheath and is the most common soft tissue tumor of the foot and ankle Giant cell tumors of the tendon sheath have a well-circumscribed multilobular appearance and often possess shallow grooves along their deep surfaces created by the underlying tendons BACKGROUND AND OBJECTIVES: Giant cell tumor of the tendon sheath (GCTTS) is a lesion of uncertain etiology. To better interpret pathogenesis and aid in the differentiation of GCTTS from other similar pathological processes we reviewed the literature and analyzed the available information Tenosynovial giant cell tumors are usually benign lesions that arise from the tendon sheath. It is unclear whether these lesions represent neoplasms or merely reactive masses. On imaging, these lesions are commonly demonstrated as localized, solitary, subcutaneous soft tissue nodules, with low T1 and T2 signal and moderate enhancement
