A Case of Chondrosarcoma in the Nasal Septum Successfully Treated with Endoscopic Resection

Abstract

Chondrosarcoma in the head and neck accounts for-% of all chondrosarcomas and chondrosarcoma arising in the nasal septum is rare. Here, we reported a case of chondrosarcoma in the nasal septum in a-year-old man who presented with left nasal obstruction for year. The standard treatment for this tumor is surgical resection, because radiation therapy and chemotherapy have limited roles. Recently, it has been reported that nasal chondrosarcoma could be removed by an endoscopic approach, which has advantages of improved cosmetic appearance and early discharge. Our case did not have evidence of skull base invasion due to intracranial extension, and was considered as a low grade malignancy therefore we resected the tumor via endoscopic approach by use of piecemeal resection. Utilizing the intraoperative frozen section pathological diagnosis, complete tumor resection was finally achieved. There has been no recurrence for years postoperatively. We considered that chondrosarcoma in the nasal septum being low grade malignancy without skull base involvement like our case could be removed by an endoscopic approach.
