Giant cell tumor of tendon sheath (localized nodular tenosynovitis).

Giant cell tumor of tendon sheath (localized nodular tenosynovitis) remains a disease of unknown origin. Thirty-five giant cell tumors of tendon sheath are reviewed in this study. High recurrence rates can be minimized with attention to accurate preoperative diagnosis and aggressive local excision. The removal of portions of tendon sheath, volar plate, periosteum, or joint capsule may be necessary in selected cases.
