INTRODUCTION Gall bladder carcinoma is rare, and metastatic gall bladder carcinoma from hepatocellular carcinoma has been reported in only a few patients. CASE PRESENTATION We present a 73-year-old man with a history of hepatitis B virus-related liver cirrhosis and hepatocellular carcinoma. He received transcatheter arterial chemoembolization, and was diagnosed to have an alpha-fetoprotein pr...

Hepatoid adenocarcinoma (HAC) is a rare neoplasm with aberrant hepatocellular differentiation. HAC occurs in extrahepatic organs such as the gastrointestinal tract, testes, ovaries, and lungs and frequently produces alpha-fetoprotein. A 69-year-old patient was diagnosed clinically with T2aN0M0, stage IB, non-small cell lung carcinoma. Because the tumor showed tight adhesion to the chest wall, w...

Hepatoid adenocarcinoma (HAC) is a rare type of extrahepatic cancer, whose pathologic features are indistinguishable from those of hepatocellular carcinoma. About thirty cases, nearly half of which occurring in the lung, have been described in patients with a normal liver. No imaging features are typical enough to allow a correct diagnosis. A localization of HAC in the soft tissues of the shoul...

Alpha-fetoprotein (AFP) is a common tumor marker for hepatocellular carcinoma (HCC). We report a unique case of an AFP-producing gastric cancer in an elderly man with known chronic hepatitis B (HBV) and a markedly elevated AFP. Thorough diagnostic imaging failed to reveal a HCC, but a gastric adenocarcinoma was found on endoscopy. After successful resection, the serum AFP normalized. On histopa...
