    This report details the twentieth case of testicular malacoplakia, a rare inflammatory condition often linked to gram-negative bacterial infections like Escherichia coli.

    Area of Science:

    • Urology
    • Pathology
    • Microbiology

    Background:

    • Testicular malacoplakia is a rare inflammatory condition.
    • It typically affects middle-aged men and presents as epididymo-orchitis or testicular enlargement.

    Observation:

    • The twentieth reported case of testicular malacoplakia is presented.
    • Clinical presentation included testicular enlargement with fibrous and soft areas.
    • Escherichia coli was identified in urine and testicular tissue.

    Findings:

    • Malacoplakia is considered a nonspecific inflammatory granulomatous lesion.
    • Ultrastructural analysis confirmed the histiocytic nature of the infiltrate and Michaelis-Gutmann bodies.
    • No bacilliform structures were observed ultrastructurally.

    Implications:

    • This case contributes to the limited world literature on testicular malacoplakia.
    • Understanding the pathogenesis involving gram-negative bacteria is crucial.
    • Further research may elucidate the specific immune response in malacoplakia.
