A Case of Extracranial Chondroma of the Skull Base / 대한이비인후과학회지

The chondroma is a benign tumor that arises from the primordial cartilaginous skeleton. Chondromas can occur in the head and neck area, usually larynx, maxilla and base of the skull, but those arising from the basisphenoid and basiocciput are extremely rare. Most of the skull base chondromas described in the literature are extended intracranially, but only five cases of extracranial chondroma of the skull base have been described so far in the world literature. The authors have experienced one case of extracranial chondroma of the skull base with good result by extirpation of the lesion through sublabial-transseptal endoscopic approach.
