    Periosteal osteosarcoma, a surface bone tumor, most commonly affects the proximal tibia in young adults. Wide surgical margins are crucial to prevent recurrence and metastasis, especially for femoral lesions.

    Area of Science:

    • Orthopedic Oncology
    • Surgical Pathology

    Background:

    • Periosteal osteosarcoma is a rare surface bone tumor.
    • It lacks medullary involvement, distinguishing it from other osteosarcomas.

    Purpose of the Study:

    • To analyze demographic and clinical features of periosteal osteosarcoma.
    • To evaluate the impact of surgical margins on treatment outcomes.
    • To identify specific challenges in managing femoral periosteal osteosarcoma.

    Main Methods:

    • Retrospective review of 22 Mayo Clinic cases and 30 additional referred cases.
    • Analysis of demographic data, tumor site, presenting symptoms, and treatment outcomes.
    • Comparison of recurrence and metastasis rates based on surgical margin width and tumor location.

    Main Results:

    • The average age at diagnosis was 20.5 years.
    • The proximal tibia was the most frequent tumor site.
    • Inadequate surgical margins correlated with higher rates of local recurrence and metastasis.
    • Femoral lesions showed a high recurrence/metastasis rate even with wide margins.

    Conclusions:

    • Periosteal osteosarcoma predominantly affects young adults, with the proximal tibia being the most common site.
    • Achieving wide surgical margins is critical for successful treatment.
    • Femoral lesions may necessitate more aggressive surgical approaches due to higher recurrence and metastasis rates.
