Ameloblastic fibrosarcoma is a very rare malignant odontogenic tumor. Ameloblastic fibrosarcoma consists of benign epithelial components with the same features as those of ameloblastic fibroma, as well as malignant mesenchymal components. We report a case of ameloblastic fibrosarcoma arising in the mandible. A 32-year-old woman underwent left hemimandiblectomy, supraomohyoid neck dissection, and reconstruction. Immunohistochemically, the Ki-67 labeling index was low in the epithelial components of the tumor (1.6 %), but high in the malignant mesenchymal components (19.8 %). After operation, adjuvant chemotherapy was administered. There was no recurrence or metastasis 3 years after surgery.
