Giant Cell Tumor of the Temporal Bone / 대한이비인후과학회지

ABSTRACT

Giant cell tumor of bone is an uncommon, primary neoplasm that occurs chiefly in the ends of the long bones. Giant cell tumor is rarely encountered in the skull, where it preferentially involves the sphenoid, ethmoid, and temporal bones. Radiographically, there are no characteristic findings which can be regarded as typical of a giant cell tumor. Therefore, the diagnosis must be made by biopsy. This tumor is characterized by benign histologic features, but it can be locally aggressive and can even metastasize. Complete surgical excision is the treatment of choice for giant cell tumor. We have experienced a case of giant cell tumor of the temporal bone which was removed with infratemporal fossa approach type B. So, we report with review of literatures.
