Case report 711: Parosteal osteosarcoma of left femur.
Overview
abstract
We present a patient with parosteal osteosarcoma. The lesion arose at the surface of the femur without involvement of the marrow cavity. Some 24 months following resection of the involved bone, she developed distant metastases with no evidence of local recurrence. Neither the primary nor the metastatic lesions showed high-grade malignancy.
