Chondrosarcomas are slow-growing, malignant, mesenchymal tumours occuring only rarely in the cranial bones. Only 5% of all chondrosarcomas are located in the head-neck region; the ethmoid and sphenoid sinuses are the commonest sites. Surgery is considered the treatment of choice. The benefits of radiation remain unproven and chemotherapy is largely ineffective in these conditions. We report a case of chondrosarcoma of the skull base with extension to the nasal sinuses, orbit and cranium which was managed by radiotherapy.
