  • Usually biliary phenotype but also intestinal
  • Often extends into pancreas or liver
  • Papillary carcinomas confined to ductal wall have better 10 year survival than adenocarcinomas confined to ductal wall
  • Better survival even if nodal metastases
  • Microsatellite instability is relatively frequent in papillary neoplasms of biliary tree (Mod Pathol 2002;15:1309)
  • Tumors may dedifferentiate
