Chondrosarcoma of the nasal septum extending into the maxillary sinus

A case of chondrosarcoma of the nasal septum extending into the maxillary sinus is presented. These cartilaginous tumors are rare in the head and neck, with only 21 reported in the maxilla and four in the nasal septum. Careful histologic analysis is required for correct diagnosis. The present case was treated with an en bloc ethmoidectomy and medial maxillectomy, followed by fast neutron radiation therapy. The therapeutic program is analyzed for opportunity to provide an excellent chance of cure.
