Abstract
Ameloblastic fibro-odontosarcoma (AFOS) is an extremely rare malignant odontogenic tumor. Complete surgical excision is the treatment of choice. Deaths due to disease recurrence and/or progression are documented. Here, we report the case of a 15-year-old female with multiple recurrent AFOS. She responded to chemotherapy with ifosfamide and doxorubicin consolidated by stereotactic reirradiation using cyberknife and remained in complete remission 14 months from the end of reirradiation therapy. Chemotherapy with ifosfamide and doxorubicin should be considered in advanced cases of AFOS.
