    Area of Science:

    • Hepatobiliary pathology
    • Oncology
    • Tumor biology

    Background:

    • Hepatocellular carcinoma (HCC) typically arises in cirrhotic livers.
    • Non-cirrhotic HCC is less common and may present unique histological features.
    • Understanding rare variants is crucial for accurate diagnosis and treatment.

    Observation:

    • A 51-year-old female presented with a large, well-circumscribed tumor (20 x 10 cm) in a non-cirrhotic liver.
    • Macroscopic examination revealed a central fibrous scar.
    • Histological analysis identified an unusual epithelial liver cell tumor with polygonal cells, fibrous stroma, and oncocytic changes.

    Findings:

    • Electron microscopy confirmed the presence of oncocytic features within the tumor cells.
    • The tumor represents an unusual variant of hepatocellular carcinoma.

  • Oncocytic change was a prominent characteristic of this specific liver tumor.

    • Implications:

    • This case highlights the importance of considering rare variants in liver cancer diagnosis.
    • Further research into oncocytic change in liver tumors may reveal underlying mechanisms.
    • Accurate identification of tumor variants can potentially influence patient management strategies.
