Squamous-cell carcinoma complicating chronic osteomyelitis.

R H Fitzgerald, N S Brewer, D C Dahlin

    The Journal of Bone and Joint Surgery. American Volume
    |December 11, 1976
    PubMed
    Summary

    Squamous-cell carcinoma in chronic osteomyelitis can metastasize. Differentiating benign from malignant lesions is crucial for treatment. Aggressive surgical intervention offers a good prognosis for these patients.

    Area of Science:

    • Oncology
    • Orthopedic Surgery
    • Pathology

    Background:

    • Chronic osteomyelitis can develop carcinomatous degeneration.
    • Distinguishing between benign and malignant epithelial changes is critical for patient management.
    • Low-grade squamous-cell carcinoma is common but can metastasize.

    Purpose of the Study:

    • To analyze treatment outcomes for squamous-cell carcinoma arising in chronic osteomyelitis.
    • To evaluate the necessity of routine lymphadenectomy and management of lymphadenopathy.
    • To determine prognostic factors for malignant epithelial invasion in osteomyelitic cavities.

    Main Methods:

    • Retrospective case series analysis of twenty-three patients treated at the Mayo Clinic.
    • Review of histopathological findings and treatment modalities.
    • Correlation of treatment with patient outcomes, including metastasis and survival.

    Main Results:

    • Malignant-appearing epithelium invading bone necessitates ablative surgery.
    • Inadequate surgery led to mortality in two patients.
    • Routine regional lymphadenectomy was deemed unnecessary; persistent lymphadenopathy requires intervention.

    Conclusions:

    • Prompt, aggressive surgical treatment improves prognosis for squamous-cell carcinoma in osteomyelitic cavities.
    • Early differentiation between benign and malignant lesions is key.
    • Management of regional lymphadenopathy should be guided by persistence post-amputation.
