UNASSIGNED: The aim of this study was to review the clinical, radiographic, and pathologic features of cases of @entity1347 in non-Asian @entity10479 @entity1 with clinical concern for @entity201 and compare these features with cases of @entity255 ( @entity255 ) in Asian @entity1 . A total of 10 non-Asian @entity10479 @entity1 with @entity1347 were included in this study. Nine of them underwent partial hepatic resection due to cholangiographic findings of segmental cholangiectasia with mural thickening and/or proximal biliary stricture. One was found to have markedly dilated and thickened intrahepatic bile ducts at the time of autopsy. Clinical and radiographic findings were reviewed. @entity2362 stains and immunostains for immunoglobulin G4, cluster of differentiation ( @entity4896 ), and @entity9184 were performed. Six comparison cases of @entity255 in Asian @entity10479 @entity1 were also examined. Histologic examination of resection specimens revealed markedly dilated large intrahepatic bile ducts with variable degrees of mural @entity82 , @entity1373 , @entity32 , and liver parenchymal atrophy. These changes were not associated with a ductular reaction. There was no evidence of @entity253 or @entity2835 in any cases. No gross or microscopic feature definitively separated the Asian from non-Asian @entity1 . The etiology of this disorder in non-Asian @entity10479 @entity1 is unclear. It does not appear to represent a localized variant of @entity13550 or @entity991 . The high degree of similarity shared by these cases and classic @entity255 suggests a common pathogenic mechanism, although the pathologic features tend to be less well developed in the cases from the non-Asian @entity10479 @entity1 .
