A Case of Endoscopic Treatment of a Huge Chondrosarcoma Originating from the Ethmoid Sinus / 대한이비인후과학회지

ABSTRACT

Chondrosarcoma of the ethmoid sinus is a rare malignant tumor and has a poor prognosis due to the frequent local recurrence and distant metastasis. It has unique and distinctive histologic characteristics, being composed of chondroid tumor cells with spindled cytoplasmic extensions. Wide surgical resection is the treatment of choice and radiation or chemotherapy can be combined with the surgery. The prognosis of chondrosarcoma depends on the anatomical location, resectability, and cytologic differentiation of the tumor. The authors experienced a case of huge chondrosarcoma of the left nasal cavity in a 47-year-old woman, which was resected successfully via endoscopic approach. We present the clinical characteristics, pathology, treatment, and prognosis of the tumor with a review of the literature.
