[Double occurrence of a giant-cell tumour (author's transl)]

The authors report a case of giant-cell tumour of the lower end of the radius treated by resection-arthrodesis of the wrist with cure of the lesion for 9 years. There then appeared, in the same hand, a second giant-cell tumour at the level of the first metacarpal bone which was not an extension of the first lesion. It was treated by prosthetic replacement of the first metacarpal bone. A review of the literature has shown 13 similar cases of polycentric giant-cell tumours.
