Indian Journal of Cancer. 1991 Dec; 28(4): 177-80http://imsear.searo.who.int/handle/123456789/49387Giant cell tumours (GCT) are rare in the skull bones. In the cranium the sphenoid bone is the most common site. The petrous bone is a very uncommon location for such tumours. The chance location of GCT at the base of the skull makes total surgery difficult and hazardous. A case of GCT of the petrous bone is presented. The clinical course in the patient and role of primary radiotherapy in GCT in such an unusual site is discussed.engAdultBone Neoplasms --pathologyFemaleGiant Cell Tumors --pathologyHumansOsteoma, Osteoid --pathologyPetrous BoneSkull Neoplasms --pathologyCase Reports
