title: Osteosarcoma and fibrosarcoma caused by postoperative radiotherapy for a pituitary adenoma. Case report.
abstract: Sarcomatous change is a rare complication of postoperative radiotherapy for pituitary adenomas. The authors report on what they believe to be the first case in which fibrosarcoma and, later, osteosarcoma developed during a 14-year period following surgery and radiotherapy for a nonsecreting pituitary macroadenoma.
