[The development of osteosarcoma following radiotherapy for fibrous dysplasia].
Sarcoma arising from fibrous dysplasia (FD) is rare and it is more common in polyostotic type. In this case report, we present a 41-year-old male patient who developed osteosarcoma of the left tibia 28 years after the initial diagnosis and 20 years after radiation therapy for FD. He underwent above-knee amputation, but died eight months after surgery. This case suggests that radiotherapy has no beneficial effect in the treatment of FD and that it may be associated with the development of sarcoma.
