title: Chondrosarcoma of the ethmoid sinus extending to the anterior fossa.
abstract: A 27-year-old women with chondrosarcoma of the ethmoid sinus extending to the anterior fossa had initial symptoms of blurred vision on the left and slight proptosis. Neuroradiological examination, however, disclosed that the tumor extended not only to the anterior cranial fossa, but also to the orbit, nasal cavity, and maxillary sinus. It is difficult to predict the biological behavior of chondrosarcoma by means of histological examination. The effectiveness of radiotherapy, chemotherapy, or both is also a matter of controversy. Clinical aspects of chondrosarcoma are briefly discussed.
