    High-grade ordinary osteosarcomas found juxtacortically present a diagnostic challenge. These aggressive bone tumors have a poorer prognosis and require differentiation from other juxtacortical osteosarcomas.

    Area of Science:

    • Orthopedics
    • Surgical Oncology
    • Bone Pathology

    Background:

    • Juxtacortical osteosarcomas are rare bone tumors.
    • High-grade ordinary osteosarcomas can present juxtacortically.
    • Distinguishing these from other juxtacortical types is crucial.

    Purpose of the Study:

    • To describe the clinical, radiographic, and histologic features of juxtacortical high-grade ordinary osteosarcomas.
    • To emphasize the importance of differentiating this entity due to its prognosis.

    Main Methods:

    • Retrospective review of nine patients with juxtacortical high-grade ordinary osteosarcomas.
    • Analysis of radiographic and histologic findings.
    • Correlation with patient outcomes.

    Main Results:

    • Nine patients (seven males, two females) diagnosed with juxtacortical high-grade ordinary osteosarcomas.
    • Tumor ages ranged from 9 to 62 years.
    • Radiographic appearance sometimes mimicked periosteal osteosarcomas.
    • Histology was indistinguishable from intramedullary osteosarcomas; no parosteal/periosteal features were present.
    • All patients underwent ablative surgery.
    • Seven out of nine patients died of their tumor.

    Conclusions:

    • Juxtacortical high-grade ordinary osteosarcomas represent an aggressive subtype of osteosarcoma.
    • Accurate differentiation from other juxtacortical osteosarcomas is essential for appropriate patient management and prognosis.
    • This entity carries a poorer prognosis compared to other juxtacortical osteosarcomas.
