Both halves of this image are taken from the same CT-guided core biopsy of a liver mass. The left half shows uninvolved liver parenchyma. The right half shows fibrolamellar carcinoma - a distinctive subtype of hepatocellular carcinoma. It is usually seen in young patients (majority are below 35 yrs. of age) and has favorable prognosis. The characteristic feature is the presence of fibrous bands separating lobules of tumor cells.
