Chondroblastoma of Temporal Bone / 대한이비인후과학회지

Chondroblastoma is an uncommon primary benign bone tumor that usually arises in the epiphyses of the long bones. Chondroblastoma of temporal bone is extremely rare. Its biological nature is often benign but is sometimes aggressive because of the local invasion. Recently, the authors have experienced two cases of chondroblastoma of temporal bone which were completely excised. We report these cases of chondroblastoma of the temporal bone with a review of literature.
