Abstract

Giant cell tumor of the tendon sheath and fibroma of the tendon sheath are similar benign neoplasms occurring near or within joints. The cells of giant cell tumor of the tendon sheath may be related to synovial cells, monocytes, and osteoclasts, whereas those of fibroma of the tendon sheath show myofibroblastic differentiation. But some authors consider these tumors to be different stages of the same pathologic process; fibroma of the tendon sheath is probably one end of the morphological spectrum of regression of giant cell tumor of the tendon sheath. We report a case of giant cell tumor of the tendon sheath with histologic findings similar to that of fibroma of the tendon sheath and suggest some fibroma of the tendon sheaths are indeed the end sclerosing stage of giant cell tumor of tendon sheaths.
