    Summary
    This summary is machine-generated.

    Bilateral testicular tumors present diverse histological findings. Diagnosis and therapy for the second tumor depend on the first tumor's characteristics and the interval between occurrences, with malignant lymphomas having unique considerations.

    Area of Science:

    • Urology
    • Oncology
    • Pathology

    Background:

    • Bilateral testicular tumors are rare, necessitating a review of existing literature and case series.
    • Understanding the histological concordance and discordance between bilateral testicular tumors is crucial for management.

    Purpose of the Study:

    • To analyze the histological characteristics, diagnostic approaches, therapeutic strategies, and prognostic factors of bilateral testicular tumors.
    • To compare findings from a new case series with a comprehensive literature review.

    Main Methods:

    • Literature review of 396 reported cases of bilateral testicular tumors up to 1979.
    • Analysis of 18 new cases of bilateral testicular tumors.
    • Comparison of histological types (seminoma, nonseminoma, malignant lymphoma) and their concordance/discordance.

    Main Results:

    • Literature: 217 same histology, 47 different histology, 68 malignant lymphomas, 64 unspecified.
    • New cases: 5 same histology, 6 different histology, 7 malignant lymphomas.
    • Diagnostic and therapeutic decisions are guided by the initial tumor's histology and treatment, and the interval to the second tumor.

    Conclusions:

    • Bilateral testicular tumors exhibit varied histological presentations.
    • Management strategies for the second tumor are tailored based on interval and histology.
    • Malignant lymphomas require specific diagnostic and therapeutic considerations.
    • The prognosis for bilateral germ cell tumors is not considered poor.
