Radionuclide scanning in pseudo-Kaposi's sarcoma.

T Rosen, S Martin, J K Stern

    Archives of Dermatology
    |June 1, 1979
    PubMed
    Summary

    Sodium pertechnetate Tc 99m scans can detect Kaposi's sarcoma but may yield false positives in acroanglodermatitis. This suggests the scan is not ideal for differentiating these conditions but may guide acroangiodermatitis therapy.

    Area of Science:

    • Nuclear medicine
    • Dermatology
    • Oncology

    Background:

    • Sodium pertechnetate Tc 99m radionuclide scanning is a sensitive method for detecting Kaposi's sarcoma.
    • Kaposi's sarcoma and acroanglodermatitis (pseudo-Kaposi's sarcoma) can present with similar clinical and histological features.

    Observation:

    • A case report details a "false-positive" sodium pertechnetate Tc 99m scan in a patient diagnosed with acroanglodermatitis.
    • This finding indicates a potential limitation of the scanning technique in differentiating between the two conditions.

    Findings:

    • The study suggests that sodium pertechnetate Tc 99m scanning may not be a reliable tool for the differential diagnosis of Kaposi's sarcoma and acroanglodermatitis.
    • The scan's utility might lie in assessing underlying vascular anomalies in acroanglodermatitis.

    Implications:

    • This research highlights the importance of considering alternative diagnostic approaches when faced with suspected Kaposi's sarcoma.
    • The findings suggest a potential role for technetium scans in treatment planning for acroanglodermatitis, focusing on the management of vascular abnormalities.
