Management of Nasal Cavity Chondrosarcoma: About a Case and Review of the Literature

Background: We report here a case of nasal cavity chondrosarcoma and its treatment. Methods: A women aged of 29 years old presented a long history of nasal obstruction. He was diagnosed with nasal cavity chondrosarcoma. Loco regional extension in the CT scan showed involvement of the right nasal cavity, and suspected involvement of the medial wall of the orbit. She had surgical excision with removal of the tumor. Given the positive margins, adjuvant radiotherapy was indicated. The radiotherapy was delivered with intensity modulated radiation therapy (IMRT) technique in order to overcome anatomical complexity of the region, cover the tumor bed and preserve the organs at risk. Results: The patient remains without recurrence with more than 12 months of follow-up. Conclusions: Radical excision of the tumor is the treatment of choice, but our results show a high level of efficacy for fractionated photon radiotherapy after surgery, in keeping with other series, particularly now with the advent of new radiotherapy techniques. This should encourage the further development of sophisticated photon radiotherapy.
