Hepatoid Adenocarcinoma of the Stomach with Liver Metastasis Mimicking Hepatocellular Carcinoma: Se Hyung Kim, Byung Ihn Choi; Journal of the Korean Liver Cancer Study Group. 2003;3(1):65-68. Published online July 31, 2003

Abstract PDF: We describe a case of hepatoid adenocarcinoma of the stomach with liver metastasis mimicking hepatocellular carcinoma (HCC). Ultrasonography demonstrated an ill-defined heterogeneous hyperechoic mass at right lobe of the liver and high echoic thrombi that filled both portal veins. Contrast enhanced CT scan revealed an ill-defined low attenuated lesion in right lobe of the liver and left portal vein and posterior branch of right portal vein that were filled with low attenuated tumor thrombi. Diffuse and irregular wall thickening with enhancement was also visualized on the posterior wall of the stomach from cardia to angle. Endoscopic biopsy for gastric lesion and US-guided percutaneous core biopsy for hepatic mass were performed. Microscopic examination and immunohistochemical staining revealed aFP-producing hepatoid adenocarcinoma of the stomach and metastatic tumor of the liver.

Atypical Hepatocellular Carcinoma in an AIDS Patient: Se Hyung Kim, Joon Koo Han; Journal of the Korean Liver Cancer Study Group. 2003;3(1):80-82. Published online July 31, 2003

Abstract PDF: We described a case of atypical hepatocellular carcinoma (HCC) in an AIDS patient. The patient presented with fever and leukocytosis and had no evidence of chronic hepatitis clinically and radiologically. Ultrasonography showed multiple variable sized low echoic nodules, which had low echoic peripheral halo, in both lobes of the liver. Contrast enhanced CT scan showed multiple well demarcated and low attenuated nodules in both lobes of the liver. Hepatic and portal veins were intact. Percutaneous core biopsy for hepatic nodules revealed cod-like distribution of malignant cells and HCC with trabecular type was finally diagnosed.

Spontaneous Total Necrotic Hepatocellular Carcinoma: Young Jun Kim, Jun Yong Jeong, Kyong Ho Lee, Se Hyung Kim, Joon Koo Han, Byung Ihn Choi; Journal of the Korean Liver Cancer Study Group. 2002;2(1):73-75. Published online July 31, 2002

Abstract PDF: Spontaneous total necrosis of hepatocellular carcinoma is extremely rare, with only 16 cases reported in the English literature. In this report, we describe a case of spontaneous totally necrotic hepatocellular carcinoma in a 53-year-old man who was previously healthy. The hepatic mass was incidentally found. The viral markers for hepatitis B and C were negative and alpha-fetoprotein was normal. Ultrasonography revealed hypoechoic mass with peripheral high echoic rim. On CT, the mass was hypodense in both hepatic arterial phase and portal venous phase. Subtle capsular enhancement was noted in portal venous phase CT. The patient underwent hepatic segmentectomy. The resected hepatic segment revealed 4.5 cm sized, well encapsulated, and nearly totally necrotic mass. On microscopic examination, the ghost cells of hepatocellular carcinoma were found in totally necrotic tissue, supporting diagnosis of hepatocellular carcinoma.
