Abstract
|
|
|
It is not uncommon for sarcomatous transformation of giant cell tumor of bone to occur after radiation, but osteosarcoma arising from giant cell tumor after surgical treatment is very rare and remains an aggressive form of sarcoma of bone with
high mortality rate. We experienced 2 cases in whom a osteosarcoma developed long after benign giant cell tumor of bone was removed surgically from the same site. Malignant transformation was presented at 2 years 1 month and 9 years 8 months each after initial surgery. We describe our experience concerning clinical features, methods of treatment of outcomes of osteosarcoma arising from giant cell tumor.
