title: Intracortical low grade osteosarcoma. A unique case and review of the literature on intracortical osteosarcoma.
abstract: The thirteenth case of an intracortical osteosarcoma is presented. According to the authors' knowledge, this case appears to be the first report of an intracortical low grade osteosarcoma of the fibrous dysplasia-like variant in the femur. All other cases (except one small cell variant) reported in the literature were histologically diagnosed as high grade osteoblastic or sclerotic variants. The finding of both a low grade and a small cell variant of osteosarcoma supports the concept that intracortical osteosarcoma rather represents a distinct entity defined by location than an early detected conventional medullary osteosarcoma.
