True giant-cell tumour of the mastoid. A case report

The authors describe a case of a very extensive giant-cell tumour of the mastoid in a 5 1/2-year-old girl. This is very rare, and it is only the fourth one documented in the English literature. The age of the patient is of great importance, as well as the fact that the middle and the inner ear were not involved, although the tumour was very extensive. Radical surgical removal of the tumour was performed, as the treatment of choice, without any signs of recurrence one year post-operatively. The diagnostic problems of giant-cell lesions of bones are briefly discussed.
