title: Osteosarcoma following radiotherapy: a case report.
abstract: The case of a patient with postirradiation osteosarcoma is presented. The 20-year-old female was diagnosed as having osteosarcoma by histological examination of an open biopsy specimen. She underwent surgery for pure dysgerminoma and received adjuvant postoperative radiotherapy, 40 Gy to the pelvis and 30 Gy to the para-aortic region, 11 years ago. This case satisfied the criteria for radiation-induced osteosarcoma proposed by Cahan et al. Radiation-induced osteosarcoma is rare, but the possibility of that must be borne in mind.
