Two cases of metachronous multicentric giant cell tumour of bone are reported. One patient had tumours in the tibia and the femur, the second tumour appearing five years after the first. The other patient developed tumours in the tibia and the radius, the second tumour appearing two years and nine months after the first. The metachronous tumours, in both cases, were clinically and radiologically more aggressive than the initial tumours. Treatment with curettage and bone grafting proved to be ineffective for these tumours and en-bloc excision was required for cure.
