Chondrosarcoma of the nasal septum

Chondrosarcoma of the nasal septum is a very rare malignant tumor in the head and neck region. To diagnose chondrosarcoma, it is challenging to obtain an exact initial impression just by simple physical examination. Therefore, imaging studies are useful in the initial assessment of chondrosarcoma. Pathological confirmation is necessary for a definitive diagnosis of chondrosarcoma. In the treatment of chondrosarcoma, complete surgical resection is most effective, but often difficult. We report a patient with chondrosarcoma misdiagnosed with nasal septal deviation causing nasal obstruction. The patient underwent endoscopic surgical resection via an external rhinoplasty approach. The pathological diagnosis of the patient was chondrosarcoma with pathological Grade 1. The patient has been regularly followed up to date without recurrence.
