Background. FDG-PET scan detects extrahepatic metastases in 20% of patients with colorectal liver metastases but it is reported to have approximately 16% false negative rates. Patients and Methods. Patients who had PET scan for metastatic colorectal cancer at Westmead Hospital between March 2006 and March 2010 were reviewed retrospectively. The results of PET scan were correlated with tumour ch...

Invasive micropapillary carcinoma (IMPC) was originally described as a distinctive type of invasive carcinoma in the breast, but it has not been recognized as a histological type of the extrahepatic bile duct cancer. The present study demonstrated clinicopathological features and patient prognosis of IMPC. We examined histological reviews of 93 consecutive cases of the extrahepatic bile duct ca...

BACKGROUND According to the literature, benign bile duct tumors are exceedingly uncommon. To the best of our knowledge, we report the largest extrahepatic bile duct villous adenoma described in the literature. CASE PRESENTATION We present a case of a 77-year-old Caucasian woman with obstructive jaundice. Laboratory tests revealed that she had elevated bilirubin and liver enzyme levels. A comp...

Thirteen patients with primary hepatocellular cancer were studied to outline criteria for resectability in patients with large liver tumours. The mean age was 34 and the mean tumour diameter 13 cm (range 7-18 cm). Five of the tumours had a diameter of 15 cm or more. Extensive radiological investigations showed that seven of the patients had tumours of both right and left lobes of the liver, 10 ...

OBJECTIVE To describe the appearance of transient hepatic attenuation differences (THADs) of extrahepatic origin. MATERIALS AND METHODS Five cases of THADs produced by compression of the extrahepatic portal vein at its confluence with the splenic vein were identified prospectively over a four-month period. Two additional cases of peripheral THADs resulting from main portal vein thrombosis wer...

AIMS AND BACKGROUND Extrahepatic spread of hepatocellular carcinoma (HCC) diagnosed during the clinical course of the disease is not frequent; however, with the prolonged survival of HCC patients, the incidence of extrahepatic metastases seems to be increasing. METHODS AND STUDY DESIGN We present four unusual cases of extrahepatic metastasis from HCC: the first concerns a patient who underwen...

The hepatic artery aneurysms are rare, especially in interahepatic branches. The frequency consists of 75-80% extrahepatic and 20-25% intrahepatic. Catheterization is achieved usually from common femoral artery, other methods implemented in the case of unsuccessful catheterization from femoral artery, are translumbar and brachial catheterization.The study consist of 565 patients that were refer...

Hepatic cirrhosis is the clinical and pathologic result of a multifactorial chronic liver injury. It is well known that cirrhosis is the origin of multiple extrahepatic abdominal complications and a markedly increased risk of hepatocellular carcinoma (HCC). This tumor is the sixth most common malignancy worldwide and the third most common cause of cancer related death. With the rising incidence...

We have studied the expression of three P-450 gene subfamilies in hepatic and extrahepatic tissues using the sensitive RNAse A protection assay. Members of the P450IA subfamily, which encodes the major methylcholanthrene-inducible cytochromes P-450, were found to be not expressed in extrahepatic tissues of untreated animals, raising the question whether these P-450 play a role in the metabolism...

Extrahepatic bile duct carcinoma is one of the most extremely aggressive cancers with poor prognosis after curative resection. Syndecan-1 and E-cadherin are transmembrane glycoproteins, and have important roles in cell-cell adhesion and tumor progression. In this study, we examined 84 surgically resected cases of extrahepatic bile duct adenocarcinoma to clarify clinicopathological significance ...
