Bone injury and late giant-cell tumor occurrence: a possible relation. A case report.

A giant-cell tumor of the upper end of the fibula, five years after a documented bone injury at the same site is reported. The histologic diagnosis was corroborated by the patient's age, tumor localization, radiologic and pathologic aspects. The role of a bone injury as a promoting factor in the development of this tumor is discussed. The tumoral occurrence as a reactive process to trauma in this case may not be ruled out.
