Osteosarcomas usually occur as secondary tumors after radiation therapy or chemotherapy. Without a history of irradiation to the head and neck area, primary osteosarcoma of the turbinate is extremely rare.

Despite dose intensification with conventional cytotoxic therapies, survival times for dogs and humans diagnosed with high-grade osteosarcoma have not changed in the past 20 years, with the principal cause of ...
