Summary
Combined hepatocellular-cholangiocarcinoma (HCC-CC), a rare liver cancer, can present as a hypovascular tumor with elevated alpha-fetoprotein (AFP). This case highlights key diagnostic indicators for this aggressive cancer.
Area of Science:
- Hepatology
- Oncology
- Gastroenterology
Background:
- Combined hepatocellular-cholangiocarcinoma (HCC-CC) is an uncommon primary liver malignancy.
- Hepatitis B virus (HBV) and Hepatitis C virus (HCV) are known risk factors for liver diseases.
Observation:
- A patient with HBV and HCV presented with abdominal pain, fever, and significantly elevated alpha-fetoprotein (AFP).
- Imaging revealed a hypodense, hypovascular liver mass with lymphadenopathy and portal vein occlusion.
Findings:
- Percutaneous biopsy confirmed the diagnosis of HCC-CC.
- The tumor exhibited hypovascularity on hepatic angiogram.
Implications:
- HCC-CC should be suspected in cases of hypovascular liver tumors with markedly elevated AFP and regional lymphadenopathy.
- Early consideration of HCC-CC in patients with risk factors and suggestive clinical/imaging findings is crucial for timely diagnosis and management.
