Extrahepatic Vascular Parasitization by a Hepatocellular Carcinoma

Unusual extrahepatic metastatic sites from hepatocellular carcinoma.

The author examined unusual extrahepatic metastatic sites from liver hepatocellular carcinomas (HCCs) in autopsy and surgical files at our laboratory in the last 10 years. In autopsy cases (n=31), extrahepatic metastases were present in 21 cases (68%). The most common metastatic sites were lung (n=18). Unusual extrahepatic metastatic sites in the autopsy series were abdominal regional lymph nod...

Hepatocellular carcinoma in a sheep

At necropsy of a five-year-old sheep, a pear shaped, lobular yellow-brownish mass measuring about 12 ×15 × 20 cm was found to involve the right hepatic lobe. Microscopic examination revealed two trabecularand solid patterns of neoplastic hepatocytes. In solid pattern, there were numerous tumoral giant cells thatcontain one or more large hyperchromatic bizarre-shaped nuclei scattered among clust...

Extrahepatic recurrence of hepatocellular carcinoma after curative hepatic resection

BACKGROUNDS/AIMS This study was designed to compare the recurrence patterns after curative hepatectomy, to compare the prognosis according to the initial site of metastasis, and to investigate the independent predictive factors associated with extrahepatic recurrence in hepatocellular carcinoma (HCC) patients after curative hepatectomy. METHODS From January 2000 to July 2009, 307 patients und...

Extrahepatic Bile Duct Hepatocellular Carcinoma without Primary Hepatic Parenchymal Lesions

Obstructive jaundice is rarely a presenting symptom of hepatocellular carcinoma (HCC). Most of the cases in the literature describing obstructive jaundice by HCC have a major hepatic component. Extrahepatic HCCs without primary hepatic parenchymal lesions are extremely rare. We encountered a case of extrahepatic HCC without primary hepatic parenchymal lesions in a 36-year-old man who presented ...
