    Area of Science:

    • Hepatobiliary pathology
    • Surgical oncology
    • Gastroenterology

    Background:

    • Hepatobiliary cystadenomas are rare cystic neoplasms of the liver, often presenting diagnostic challenges.
    • Understanding their distinct histological and immunohistochemical profiles is crucial for accurate diagnosis and management.

    Observation:

    • A case report details a 45-year-old female with an 18x12x8 cm multifocal hepatobiliary cystadenoma.
    • The tumor contained yellowish fluid and was lined by a columnar epithelium with basally located nuclei.
    • Immunohistochemical analysis revealed cytokeratin 19 expression, characteristic of bile duct epithelium.

    Findings:

    • The histological and immunohistochemical findings support the diagnosis of hepatobiliary cystadenoma.
    • Cytokeratin 19 positivity is a key marker, linking the tumor to biliary differentiation.
