We report a case of chondroblastoma of the middle cranial fossa, probably arising from the (infra) mandibular fossa, and expanding to the attic and external auditory canal that was successfully removed using a middle cranial fossa approach. No recurrences occurred during an 8-year postoperative follow-up period. Initial biopsy findings suggested a pathological diagnosis of giant cell tumor that was later confirmed to be a chondroblastoma based on an immunohisto- chemical study of S-100. This case study suggests a profound understanding of the clinical features, histopathological characteristics, and possible treatment of chondroblastoma.
