The gallbladder, in pathology (and general surgery), is a growth industry... due to the worsening obesity epidemic.

Normal

Anatomy

  • Body.
  • Fundus.
  • Neck.

Variations:

  • Hartmann's pouch - invagination of the gallbladder wall at the origin of the cystic duct.

Image:

Histology

  • No muscularis mucosae.
  • Small amount of lymphocytes in the lamina propria.

Note:

  • As there is no muscularis mucosae, the cancer staging is different; pT1a is lamina propria invasion. pT1b is muscle layer invasion.

  • Normal gallbladder - intermed. mag. (WC/Nephron)

Overview

Most common:

  • Cholelithiasis with cholecystitis.

Less common pathologic diagnoses

Adenomyoma of the gallbladder

  • AKA gallbladder adenomyosis.

  • AKA gallbladder adenomyoma.

General

  • Glands in muscle.
  • Analogous to what happens in the uterus.
  • Significance - may mimic malignant tumours of the gallbladder.[2][3]
  • Uncommon.

Gross

  • Cystic spaces (Rokitansky-Aschoff sinuses) - may be seen on imaging.[4][5]
  • Gallbladder wall thickening.

Microscopic

Features:[6]

  • Glands in muscularis propria of the gallbladder wall - key feature.

Gallbladder polyps

General

  • Polyps are significant as they may be adenomatous, i.e. pre-cancerous.
  • These are similar to polyps found elsewhere GI tract.

Microscopic

See intestinal polyps.

Flat dysplasia:[8]

  • Nuclear changes.
    • Increased NC ratio.
    • Hyperchromasia (essential).
    • +/-Intestinal metaplasia --> goblet cells.

Gallbladder diverticulosis

Pancreatic heterotopia near cystic duct in 35 year old women. A. The cystic duct margin is at right; the heterotopia, at left. This cannot be a portion of the pancreas because the cystic duct margin lies proximal to the common bile duct. B. Pancreatic ducts with lobular proliferation, but without the inflammation that would usually be present were this obstruction by a gallstone. C. Nuclei of the duct and the proliferated bile ductules are bland. D. Acini are unremarkable; no pancreatic islets were seen in this case.

Premalignant lesions

General

  • Metaplasia associated with carcinoma.[10]

Hypothesis:[11]

  • Antral type metaplasia --> intestinal metaplasia --> dysplasia --> carcinoma.

Intestinal metaplasia of the gallbladder

Main article: Intestinal metaplasia of the gallbladder

Antral type metaplasia

General

  • AKA pyloric metaplasia, pseudopyloric metaplasia, mucous gland metaplasia.[12]

Microscopic

Features:[12]

  • Columnar cells with:
    • Abundant, pale, apical mucin.
    • Small basal nucleus.
  • Cells often in nests -- below luminal surface.
  • Cells vaguely resemble foveollar epithelium of the stomach.

Notes:

  • May look similar to cells of the gallbladder neck[12] and common bile duct.[13]
    • These glandular cells are not as columnar and have less well-defined cell borders.
      • Cells with antral type metaplasia >2:1 (height:width), benign mucosal glands <2:1.
