Periosteal osteogenic sarcoma
Periosteal osteogenic sarcoma
Definition
An intermediate grade malignant bone-forming mesenchymal neoplasm with chondroblastic differentiation. It arises from the surface of the bone and affects the diaphysis or diaphyseal- metaphyseal portion of the long bones. A painless mass or swelling is the most common clinical sign. It is associated with a better prognosis than conventional osteosarcoma.
Also known as juxtacortical chondroblastic osteosarcoma, periosteal osteosarcoma, periosteal osteosarcoma (morphologic abnormality) — per MONDO
