title: "Borderline" giant cell tumor of the tendon sheath in the hand: to amputate or not? Case report.
abstract: Giant cell tumors of the tendon sheath are usually benign, but their tendency to recur is well documented. Malignant giant cell tumors are extremely rare and their prognosis is very poor. We report a case of a "borderline" giant cell tumor of the tendon sheath and the puzzle in determining the right therapy.
