Malacoplakia of epididymis

J G Guccion, U P Thorgeirsson, B H Smith

    Urology
    |December 1, 1978
    PubMed
    Summary

    This study describes malacoplakia in the epididymis, a rare condition. Bacterial bodies within macrophages suggest a potential role in the disease's development.

    Area of Science:

    • Urology
    • Pathology
    • Microbiology

    Background:

    • Malacoplakia is a rare inflammatory condition characterized by the presence of specific intracellular inclusions called Michaelis-Guttmann bodies.
    • While typically affecting the urinary tract, localized presentations can occur in other organs.

    Observation:

    • This report details a unique case of malacoplakia specifically localized to the epididymis.
    • Ultrastructural examination was performed on affected tissues to investigate the cellular and subcellular pathology.

    Findings:

    • The ultrastructural study identified bacterial bodies within the phagolysosomes of macrophages in malacoplakic lesions.
    • These findings suggest that macrophages are actively engulfing bacterial material in the affected epididymis.

    Implications:

    • The presence of phagocytosed bacteria in malacoplakic macrophages points to a potential infectious etiology or trigger for this condition.
    • Further research into the specific bacterial species and their interaction with macrophages may elucidate the pathogenesis of epididymal malacoplakia.
