title: Giant-cell tumor of the sacrum.
abstract: We have presented a case of a patient with sacral giant-cell tumor and reviewed the literature. This is a rare disease originating from the mesenchyme of bone marrow which grows out through the cortex. It is essentially benign but behaves like a malignant tumor in view of frequent recurrences and a high incidence of malignant transformation. Cure can be achieved only by complete extirpation of tumor along with surrounding soft tissue.
