    Summary

    Malignant degeneration is a severe complication of Paget's disease, with sarcoma incidence varying by population. Paget's sarcoma, often osteosarcoma, has a poor prognosis with rapid progression.

    Area of Science:

    • Orthopedics
    • Oncology
    • Pathology

    Background:

    • Paget's disease of bone is a chronic condition of unknown etiology.
    • Malignant degeneration, specifically sarcoma, represents its most serious complication.
    • The incidence of Paget's sarcoma varies significantly across different populations.

    Purpose of the Study:

    • To review the incidence, anatomical distribution, histological subtypes, radiographic features, and prognosis of Paget's sarcoma.
    • To highlight the critical nature of malignant transformation in Paget's disease.

    Main Methods:

    • Review of literature on Paget's disease and associated sarcomas.
    • Analysis of reported cases regarding incidence, location, histology, imaging, and outcomes.

    Main Results:

    • Sarcoma incidence ranges from 0.9% to 20%.
    • Common sites include femur, humerus, pelvis, skull, and tibia; spine involvement is rare.
    • Osteosarcoma comprises approximately 50% of histological types; others are rare.
    • Radiographic findings include lytic lesions, cortical destruction, and soft tissue masses; periosteal response is uncommon.
    • Prognosis is generally poor with rapid progression and rare long-term survival.

    Conclusions:

    • Paget's sarcoma is a rare but devastating complication of Paget's disease.
    • Early recognition of radiographic signs is crucial for timely management.
    • The prognosis remains grim, emphasizing the need for further research into treatment strategies.
