Definition / general
  • Suggested route for development of invasive carcinoma of gallbladder (Arch Pathol Lab Med 2005;129:386)

    Gallstones → chronic inflammation → antral type metaplasia → intestinal metaplasia → dysplasia → carcinoma

  • Major pathway to invasive gallbladder carcinoma is via dysplasia; adenomas do not appear to be important precursors
  • Hyperplasia may not be part of this sequence
