    Pigmented villonodular synovitis can affect bones, presenting unusual manifestations. Surgical treatment is effective for these rare osseous involvements, even when mimicking tumors.

    Area of Science:

    • Orthopedic Surgery
    • Oncology
    • Radiology

    Background:

    • Pigmented villonodular synovitis (PVNS) is a rare condition affecting joints.
    • Bone involvement in PVNS is uncommon and its presentation is not well-defined.

    Observation:

    • This report details six cases of PVNS with osseous involvement among 47 total cases.
    • Locations included the ankle, wrist, elbow, scapula, hip, and knee.
    • Lesions in the ankle, wrist, and elbow mimicked neoplastic processes.

    Findings:

    • PVNS demonstrated bizarre osseous manifestations across multiple joints.
    • The peculiar appearance of lesions at the ankle, wrist, and elbow mimicked bone neoplasms.
    • All six cases with bone involvement were successfully treated surgically.

    Implications:

    • Surgical intervention is the standard treatment for PVNS with bone involvement.
    • Radiologists and orthopedic surgeons should consider PVNS in the differential diagnosis of bone lesions with unusual presentations.
    • Further research into the pathogenesis of osseous involvement in PVNS is warranted.
