Bile Duct Carcinomas with Marked Extracellular or Intracellular Mucin Accumulation: Mucinous and Signet Ring Cell Carcinomas

“…Most of the mucinous hepatic cholangiocarcinomas develop within the liver, but other primary sites also occur, including the extrahepatic bile duct (Sakamoto et al 1995;Yamanaka 1996;Mizukami et al 1999;Kenjo et al 2000), the cystic duct (Oku et al 2006), and the ampulla of Vater (Malik et al 1992;Seidel et al 2002;Wolfson 2002;Inagaki et al 2007).
