ABSTRACT
Primary adenosquamous carcinoma (ASC) of the liver is a rare subtype of cholangiocarcinoma that comprises both adenocarcinoma and squamous cell carcinoma components. We report a 48-year-old woman with advanced primary ASC and small cell carcinoma of the liver who had extrahepatic metastasis and received multiple chemotherapy regimens. After first presenting with upper abdominal pain, imaging revealed a 10.2 × 9.5 cm mass in the right lobe of the liver with lymph node and lung metastases. A liver tumor biopsy revealed adenocarcinoma and squamous cell carcinoma components, leading to a diagnosis of advanced primary ASC of the liver. The tumor shrank with gemcitabine/cisplatin therapy; however, neuron-specific enolase (NSE) and CYFRA levels were increased and the tumor grew. Next, hepatic arterial infusion chemotherapy using 5-fluorouracil and cisplatin decreased NSE and CYFRA levels and suppressed tumor growth. However, due to tumor growth, she died 14 months post-initial diagnosis. Post-autopsy pathology revealed a mixture of CD56- and synaptophysin-positive small cell carcinoma component in addition to ASC. We report a rare advanced primary ASC with small cell carcinoma of the liver diagnosed at autopsy.
