Chondrogenic neoplasms of the nasal cavity.

Chondrogenic neoplasms of the nasal cavity are rare. Clinically, presentation is often late, with expansion and destruction of the middle facial skeleton. Local radical surgical excision is the preferred treatment, with regular life-long follow-up. Risk of local recurrence and distant metastases may occur many years after initial treatment. All chondrogenic tumours should be carefully followed up because the natural course of the disease may not match the histological differentiation.
