Chondroblastoma of the Temporal Bone

Abstract

A 29 years male with a chief complaint of a hearing loss presented with the external auditory meatus blocked by a painless mass. The mass was removed by the middle cranial fossa approach, and the pathological diagnosis was chondroblastoma with low grade malignancy. Two years later, the tumor recurred in the base of middle cranial fossa, which was also removed by the same approach. The diagnostic and therapeutic problems of this rare tumor were discussed.
