Fibrolamellar carcinoma (FLC) is a rare variant of hepatocellular carcinoma, 
occurring in children and young adults without underlying liver disease. The 
diagnosis is based on morphological characteristics of the tumor, supplemented 
by immunohistochemistry and/or genetic testing. Recently, the presence of a 
characteristic DNAJB1-PRKACA fusion gene has been associated with FLC. Herein, 
we report a case of FLC presenting as peritoneal carcinomatosis in a 14-year-old 
female. Interestingly, no liver tumor was seen on imaging, and an alternative 
possibility is that the tumor arose outside the liver as a hepatoid carcinoma 
with fibrolamellar features.
