Giant cell tumor involving radial diaphysis

涉及桡骨干的骨巨细胞瘤1例报道(英文)

Giant cell tumor (GCT) of the bone is a benign but locally aggressive & destructive lesion. This tumor is usually seen in patients over 20 years of age. Less than 2% are found in part with open epiphysis. The epiphyseal portion of the bone is characteristic site of giant cell tumor. In rare instances, giant cell tumor can occur in the diaphysis of long tubular bone without involving the epiphysis. Although age, clinical and radiological features are helpful, it is still the histology that helps to clinch the diagnosis. It is important to distinguish giant cell tumor of diaphysis from the giant cell rich lesions, more common in this site.
