    Hepatic granulomas, found in 2.4%-10% of liver biopsies, often have unclear causes. This review details their pathology, associated diseases like sarcoidosis and tuberculosis, and diagnostic approaches.

    Area of Science:

    • Hepatology
    • Pathology
    • Immunology

    Background:

    • Hepatic granulomas are observed in 2.4%-10% of liver biopsies.
    • Their pathogenesis and clinical significance are frequently unclear.
    • Commonly associated conditions include sarcoidosis and tuberculosis, with undetermined etiology in up to 36% of cases.

    Purpose of the Study:

    • To describe the histopathogenesis and morphology of hepatic granulomas.
    • To review associated diseases, focusing on clinical, pathological, and diagnostic aspects.
    • To provide insights into the work-up and management of undiagnosed cases.

    Main Methods:

    • Literature review of hepatic granulomas.
    • Analysis of histopathogenesis and morphology.
    • Review of clinical, pathological, and diagnostic features of associated diseases.

    Main Results:

    • Hepatic granulomas present varied etiologies, often linked to systemic diseases.
    • Sarcoidosis and tuberculosis are leading causes.
    • Undiagnosed cases may present with prolonged fever of unknown origin.

    Conclusions:

    • Understanding the histopathology and associated conditions is crucial for diagnosis.
    • A systematic diagnostic approach is necessary for undiagnosed hepatic granulomas.
    • Management strategies for undiagnosed cases require careful consideration.
