Radiation-induced osteosarcoma of the jaw treated with skull base surgery

Head and neck osteosarcomas are rare. A 33-year-old woman received radiation therapy for lymphoepithelioma of the epipharynx in her childhood. After twenty-two years, she presented with a swelling of the right cheek. We did a work up, and diagnosed her radiation-induced osteosarcoma of the jaw. We treated her with neoadjuvant chemotherapy, surgery including skull base resection, and adjuvant chemo-therapy. A small skin recurrence developed after one year, but it was resected under local anesthesia, and there have been no recurrences since. We think that skull base surgery with a combined approach is a useful method in therapy for osteosarcomas in the skull base region. (author)
