Giant cell tumor is among the rare tumors of the bone. We present a case of
metacarpal giant cell tumor with radiographic, computed tomographic (CT) a
nd histologic findings, as well as grey scale and Doppler sonographic featu
res. We also present the "doughnut"-shaped appearance on scintigraphy of th
e lesion, which has not been shown on a metacarpal giant cell tumor. (C) 20
