Abstract
Intrahepatic cholangiocarcinoma (ICC) is reported to develop in non-biliary chronic advanced liver diseases (CALD). Herein, we characterize the pathological features of ICC arising in CALD in comparison with those in non-CALD livers. Of 471 surgically resected cases of ICC in Kanazawa, Japan and Seoul, Korea, 53 were associated with CALD (group A), while the remaining 418 arose in otherwise normal livers (group B). When ICC were classified into bile duct type, bile ductular type, variants, and intraductal papillary neoplasm of the bile duct (IPNB), the whole spectrum of subtypes were found in group A; the majority of ICC belonged to the bile duct type in both groups. In group A, bile ductular type was rather frequent (22.6%) compared with group B (8.4%). IPNB was more frequent in group B (22.5%) than group A (3.8%), and in group B, frequent in Seoul cases (24.8%), but rare in Kanazawa cases (2.3%). Variants of ICC were rare in both groups. These results imply that cholangiocarcinogenesis itself is upregulated in group A in comparison with group B and that the bile ductular type is specifically related to group A. Some unique environmental factors in Seoul may be responsible for the frequent development of IPNB.

Abstract
Intrahepatic cholangiocarcinoma (ICC) arises from the lining epithelium and peribiliary glands of the intrahepatic biliary tree and shows variable cholangiocytic differentiation. To date, ICC was largely classified into adenocarcinoma and rare variants. Herein, we propose to subclassify the former, based on recent progress in the study of ICC including the gross classification and hepatic progenitor/stem cells and on the pathological similarities between biliary and pancreatic neoplasms. That is, ICC is classifiable into the conventional (bile duct) type, the bile ductular type, the intraductal neoplasm type and rare variants. The conventional type is further divided into the small duct type (peripheral type) and large bile duct type (perihilar type). The former is a tubular or micropapillary adenocarcinoma while the latter involves the intrahepatic large bile duct. Bile ductular type resembles proliferated bile ductules and shows a replacing growth of the hepatic parenchyma. Hepatic progenitor cell or stem cell phenotypes such as neural cell adhesion molecule expression are frequently expressed in the bile ductular type. Intraductal type includes papillary and tubular neoplasms of the bile duct (IPNBs and ITNBs) and a superficial spreading type. IPNB and ITNB show a spectrum from a preneoplastic borderline lesion to carcinoma and may have pancreatic counterparts. At invasive sites, IPNB is associated with the conventional bile duct ICC and mucinous carcinoma. Biliary mucinous cystic neoplasm with ovarian-like stroma in its wall is different from IPNB, particularly IPNB showing cystic dilatation of the affected ducts. Rare variants of ICC include squamous/adenosquamous cell carcinoma, mucinous/signet ring cell carcinoma, clear cell type, undifferentiated type, neuroendocrine carcinoma and so on. This classification of ICC may open up a new field of research of ICC and contribute to the clinical approach to ICC.

Abstract
Epithelial splenic cysts are rare entities which surgeons may not have previously encountered. Their management is based on historical studies. A 21-year-old woman presented with a cyst of the spleen that produced a high serum concentration of carbohydrate antigen CA 19-9. A partial splenectomy with removal of the entire cyst and preservation of the splenic parenchyma by laparotomy was performed and the patient made an uneventful recovery. A microscopic rupture of the wall of the cyst and blood degradation products in the fluid of the cyst were confirmed. A functional splenic parenchyma was documented 18 months after surgery. There was no infection during follow-up. Partial surgical splenectomy with resection of the entire cyst prevents recurrence and preserves splenic function.

Abstract
Mucin secreted by mucosal epithelial cells plays a role in the protection of the mucosal surface and also is involved in pathological processes. So far, MUC1-4, 5AC, 5B, 6-8, 11-13 and 15-17 genes coding the backbone mucin core protein have been identified in humans. Their diverse physiological distribution and pathological alterations have been reported. Trefoil factor family (TFF) peptides are mucin-associated molecules co-expressed with MUC mucins and involved in the maintenance of mucosal barrier and the biological behavior of epithelial and carcinoma cells. Intrahepatic biliary system is a route linking the bile canaliculi and the extrahepatic bile duct for the excretion of bile synthesized by hepatocytes. Biliary epithelial cells line in the intrahepatic biliary system, secreting mucin and other molecules involved in the maintenance and regulation of the system. In this review, the latest information regarding properties, expression profiles and regulation of MUC mucins and TFF peptides in the intrahepatic biliary system is summarized. In particular, we focus on the expression profiles and their significance of MUC mucins in developmental and normal livers, various hepatobiliary diseases and intrahepatic cholangiocarcinoma.

Abstract
Intrahepatic cholangiocarcinoma (ICC) and combined hepatocellular and cholangiocarcinoma (HC-CC) are known to arise occasionally in hepatitis-related cirrhosis, although their clinicopathological features remain unclarified. In this study, we characterized the ICC (9 cases) and ICC elements of HC-CC (11 cases) arising in nonbiliary cirrhosis. Thirty-three hepatocellular carcinomas (HCC) associated with nonbiliary cirrhosis and 24 ICC without cirrhosis were used as controls. Prominent neutrophilic infiltration was frequent in ICC with cirrhosis (78%) and ICC elements of combined HC-CC (72%). Neutrophilic infiltration-related cytokines (interleukin 8, granulocyte colony-stimulating factor [G-CSF], and granulocyte macrophage colony-stimulating factor [GM-CSF]) were expressed frequently and intensely in carcinoma cells of ICC with cirrhosis (40%, 80%, and 60%, respectively) and in ICC elements of the combined one (13%, 38%, and 63%, respectively). Interleukin 8 was expressed in 18% of ICC without cirrhosis, irrespective of neutrophilic infiltration. Neutrophilic infiltration and expression of G-CSF and GM-CSF were in parallel (P < 0.05). G-CSF and GM-CSF mRNA were detected by RT-PCR in tissue specimens expressing G-CSF and GM-CSF at the protein level. Such neutrophilic infiltration and expression of G-CSF and GM-CSF were not evident in controls. The expressions of c-kit and c-Met, as a hematopoietic and hepatic stem cell marker, were seen frequently in ICC with cirrhosis (80% and 80%, respectively) and ICC elements of the combined one (63% and 50%, respectively). The present study revealed that the frequent expression of G-CSF and GM-CSF is a characteristic of ICC with cirrhosis and ICC in combined carcinoma, probably representing a phenotype of fetal hepatic parenchymal cell. The expression of these cytokines may be causally related to prominent neutrophilic infiltration.

Abstract
BACKGROUND AND AIM Hepatocellular carcinoma (HCC) is usually associated with chronic liver diseases and liver cirrhosis, while conversely, cholangiocarcinoma (CC) usually occurs in a non-cirrhotic liver. The purpose of the present study was to evaluate CC in liver cirrhosis. METHODS Between January 1998 and December 1999, 26 patients with CC were retrospectively reviewed. The occurrence of CC in chronic hepatitis B infection-related liver cirrhosis, portal vein thrombosis (PVT) and survival were analyzed. RESULTS Twenty-six patients with CC (19 with a non-cirrhotic liver and seven with chronic hepatitis B infection-related liver cirrhosis) were included in the present study. All cases of CC in the cirrhotic group were incidentally discovered during routine screening for HCC. The mean age (+/- SD) was 58.8 +/- 14 years in the cirrhotic group and 73.2 +/- 15.9 years (P = 0.001) in the non-cirrhotic group. When compared to the cirrhotic group, the non-cirrhotic group had a higher median level of albumin (42 compared to 30 g/L, P = 0.005), bilirubin (117.5 compared to 18 micro mol/L, P = 0.01), alkaline phosphatase (291.5 compared to 100 U/L, P = 0.001) and gamma glutamyl transpeptidases (215.5 compared to 31 U/L, P = 0.001). In contrast, the cirrhotic group had a higher median prothrombin time (PT) compared to the non-cirrhotic group (18.2 compared to 12 s, P = 0.05). In the non-cirrhotic group, only one patient (5.3%) showed evidence of PVT on a computerized tomography and Doppler ultrasound, while in the cirrhotic group six patients (85.7%) had PVT (P < 0.001). The median survival period in the cirrhotic group was six months (range 2-24 months) compared to 16 months (range 6-41 months) in the non-cirrhotic group (P = 0.036). CONCLUSION CC in cirrhotic liver presented at a younger age and patients who developed CC were prone to PVT. The survival period was also shorter in comparison to that of non-cirrhotic liver patients.

Abstract
An attempt is made in this review to update the reader on recent developments and progress in the study of cholangiocarcinoma: a major primary carcinoma of the liver with a very poor prognosis. Knowledge of the cell biology and physiological functions of the cholangiocyte has recently so progressed that our understanding of cholangiocarcinogenetic mechanism is expected to follow. The first part of the review deals with semantic problems, temporal changes in the incidence of cholangiocarcinoma and geographic differences in epidemiology, etiologic factors (particularly opistorchiasis in Thailand and hepatolithiasis in the Far East), and discusses a recently disclosed role of hepatitis C virus infection (30% of cholangiocarcinoma patients have antibodies against hepatitis C virus in Japan).

Abstract
It has been shown that atypical reactive bile ductules (ARBD) display positive immunoreactivity of neural cell adhesion molecules (NCAM) and bcl-2. We investigated the clinicopathological features of intrahepatic cholangiocarcinoma (CC) arising in cases of viral hepatitis B or C (VHBC) and examined their relation to ARBD by means of immunohistochemical analysis. Sixty-eight surgical cases with CC were included in this study. The cause of the background liver disease was hepatitis B surface antigen (HBsAg)(+) in eight cases, antihepatitis C virus antibody (HCVAb)(+) in 13 cases, both HBsAg(+) and HCVAb(+) in one case, and both HBsAg(-) and HCVAb(-) in 46 cases. The average age of patients with CC arising in the HBsAg(+) group was significantly less than that of patients with CC in the HCVAb(+) group (P = 0.0192). Immunohistochemically, CC arising in the HBsAg(+) and HCVAb(+) groups was correlated with coexpression of NCAM/bcl-2 in the tumor cells (P = 0.0068 and P = 0.0382, respectively). Among the 12 cases of CC coexpressing NCAM/bcl-2, 11 were of mass-forming and peripheral type (P = 0.0437), and lymph node metastasis was a rare finding compared with CC showing negative coexpression of NCAM/bcl-2 (P = 0.0213). The tumor cells of CCs arising in VHBC have some characteristics of ARBD. In such tumors, because lymph node metastases were rarely seen and lymph node dissection did not improve patient's survival, lymph node dissection can be limited.

Abstract
Sialyl-Tn, Tn and T antigens are caused by aberrant or incomplete glycosylation of apomucins and are related to the aggressiveness of malignant neoplasms. Using 41 liver samples from patients with cholangiocarcinoma (including four with cirrhosis), 21 with combined hepatocellular-cholangiocellular carcinoma and 17 with hepatocellular carcinoma, the expression of sialyl-Tn, Tn and T antigens were characterized immunohistochemically and the correlation with apomucin profiles was evaluated. The prevalence of sialyl-Tn, Tn and T antigens expression was 89, 95 and 51% in cholangiocarcinoma without cirrhosis; 25, 75, and 0% in cholangiocarcinoma with cirrhosis; 29, 90, and 48% in combined hepatocellular-cholangiocellular carcinoma; and 0, 12 and 6% in hepatocellular carcinoma, respectively. Sialyl-Tn antigen was frequently expressed in cholangiocarcinoma without cirrhosis compared with cholangiocarcinoma with cirrhosis and combined hepatocellular-cholangiocellular carcinoma (P < 0.01). Although sialyl-Tn expression was associated with MUC1, MUC6 and MUC7 expression, the expression sites among them were not identical in the individual cases. These data suggest that the different expressions of sialyl-Tn antigen among cholangiocarcinoma without cirrhosis, cholangiocarcinoma with cirrhosis and combined hepatocellular-cholangiocellular carcinoma may reflect the biological features inherent to these tumors, such as the ability of invasion.

Abstract
This study describes the spectrum of appearances of cholangiocarcinoma on magnetic resonance (MR) sequences, including gadolinium-enhanced, fat-suppressed spoiled gradient echo images and MR cholangiography. Fifteen patients were included in the study. Histologic diagnosis was established in 11 patients by surgical resection (6 patients), percutaneous biopsy (4 patients), and open liver biopsy (1 patient). The final diagnosis was determined by correlation of the MR findings with cholangiographic studies and laboratory studies in 4 patients. MR studies were performed at 1.5 T, and the following sequences were obtained: T1-weighted spoiled gradient echo (SGE), T1-weighted fat-suppressed spin echo or SGE, T2-weighted fat-suppressed conventional or turbo spin echo, MR cholangiography, and gadolinium-enhanced T1-weighted fat-suppressed SGE images. The following determinations were made: tumor location, tumor extent, ductal dilatation, ductal wall thickness, signal intensity, enhancement pattern, and associated findings. Mass-like neoplasms were peripheral (6 patients), hilar (1 patient), and extrahepatic (2 patients). Circumferential tumors were hilar (2 patients) and extrahepatic (4 patients). All peripheral tumors were multifocal. Mass-like tumors were well-defined, rounded, and ranged from 1 to 14 cm in diameter. Circumferential tumors had less well-defined margins and measured from 3 to 15 mm in thickness. All mass-like tumors were moderately hypointense on T1-weighted images and mildly to moderately hyperintense on T2-weighted images. The circumferential tumors were iso- to moderately hypointense on T1-weighted images and iso- to mildly hyperintense on T2-weighted images. Mass-like tumors were generally well shown on non-contrast and immediate gadolinium-enhanced images, whereas circumferential tumors were poorly seen on non-contrast images and best shown on gadolinium-enhanced T1-weighted fat-suppressed images. The degree of enhancement ranged from minimal to intense on immediate gadolinium-enhanced images, with all tumors becoming more homogeneous in signal intensity on images obtained between 1 and 5 min following contrast administration. Tumor-containing lymph nodes greater than or equal to 1 cm in diameter were demonstrated in 11 out of 15 patients (73.3%). These were best shown on T2-weighted fat-suppressed images and gadolinium-enhanced fat-suppressed SGE images. MR cholangiography demonstrated the level of obstruction and degree of dilatation of the proximal biliary system in 5 out of 6 patients who underwent MR cholangiography. The spectrum of appearances of cholangiocarcinoma is demonstrable on MR images. Mass-like tumors are well shown on both pre- and post-gadolinium sequences. Circumferential tumors may cause minimally increased duct wall thickness and are most clearly shown on gadolinium-enhanced fat-suppressed SGE images obtained 1 to 5 min following gadolinium administration.
