title: Oral contraceptives and intrahepatic biliary cystadenoma having an increased level of estrogen receptor.
abstract: We report a case of intrahepatic biliary cystadenoma in a young woman who had no prior history of liver disease and who had taken oral contraceptives for one year. A 27-year-old woman was admitted to our hospital with a firm epigastric mass. At laparotomy, a large cystic mass was resected from the left hepatic lobe, and diagnosed as biliary cystadenoma. In the tumor tissue, the estrogen receptor content was 14.0 fmol/mg cytosol protein, which was much higher than the 3.0 fmol/mg cytosol protein in the surrounding liver tissue. This is the first case of biliary cystadenoma in which the estrogen receptor content was increased.
