Abstract

|
|
Low grade central osteosarcoma is an rare variant of conventional osteosarcoma and generally occurs in older age than conventional. We experienced a case of low grade osteosarcoma occurred in a 12 years old female. Moreover, it occurred multifocally in left tibia, left femoral neck and midshaft, and left acetabulum. We could not sure whether it was from synchronous or metachronous metastasis. Usually the low grade osteosarcoma progresses very slowly. But, despite this case was low grade osteosarcoma with very indolent progression, furthermore, it showed synchronous or metachronous metastasis. So we report this unusual case with review of literature.
