Metastasizing Histologically Benign Giant Cell Tumor: A Case Report / 대한정형외과학회잡지

ABSTRACT

Giant cell tumor is a relatively uncommon neoplasm with high rate of local recurrence following curettage and bone graft. The histologic grading was not proven useful in predictiog outcome. Histologically benign giant cell tumor may metastasize. We report a case of histologically benign giant cell tumor occurred at left distai femur with local recurrences and multiple pulmonary metastases which was proven by percutaneous needle aspiration lung biopsy. Recurred local lesion was treated by curettage and filling with methylmethacrylate and pulmonary metastases was treated with adriamycine and dacarbazine.
