Ameloblastic fibrosarcoma (AFS) is a rare malignant tumor composed of benign odontogenic epithelial components and malignant ectomesenchymal components. We report a case of AFS occurring in the mandible of a 15-year-old boy. The patient was referred to our department for evaluation and treatment of gingival swelling. The lesion was diagnosed as a benign ameloblastic fibroma on examination of a biopsy specimen. The lesion was excised under general anesthesia, and the pathological diagnosis was AFS. At present, the postoperative course is good, with no recurrence as of about 4 years since the operation.
