Surgical biopsy for persistent generalized lymphadenopathy.

H J Rashleigh-Belcher, C A Carne, I V Weller

    The British Journal of Surgery
    |March 1, 1986

    Summary

    Persistent generalized lymphadenopathy (PGL) in homosexual men is often linked to human T-lymphotropic virus type III (HTLV-III) antibodies. Lymph node biopsy rarely reveals specific diagnoses in these HTLV-III positive patients, suggesting a more selective biopsy approach.

    Area of Science:

    • Immunology
    • Virology
    • Pathology

    Background:

    • Persistent generalized lymphadenopathy (PGL) is a condition observed in homosexual men.
    • Human T-lymphotropic virus type III (HTLV-III) has been identified as a potential cause of PGL.

    Purpose of the Study:

    • To evaluate the diagnostic yield of lymph node biopsy in homosexual men with PGL.
    • To determine the association between HTLV-III antibodies and histological findings in PGL patients.

    Main Methods:

    • Lymph node biopsies were performed on 39 homosexual men presenting with unexplained PGL.
    • Serological testing for HTLV-III antibodies was conducted on all patients.

    Main Results:

    • Antibodies to HTLV-III were detected in 95% of the patients.

  • Histological examination revealed follicular hyperplasia in most cases (38/39).
  • One case showed caseating granulomata, indicative of tuberculosis.

    • Conclusions:

    • Clinical differentiation of HTLV-III-associated lymphadenopathy from other causes is challenging.
    • The presence of HTLV-III antibodies in PGL patients often results in non-specific histological findings.
    • A more selective approach to lymph node biopsy is recommended for patients with PGL and HTLV-III antibodies.
