Chronic cholecystitis, abbreviated CC, is a very common pathology of the gallbladder and increasing in prevalence with the expanding waist lines.

General

Epidemiology

Female, fat, fertile, family history, forty (though now getting younger... as people get fatter).

Etiology

Cholelithiasis.
Thick bile (acalculous cholecystitis).

Clinical (classic)

Constant right upper quadrant pain after a fatty meal.
Positive Murphy's sign (physical exam, with ultrasound).

Gross

+/-Cholelithiasis - strongly associated pathology.
+/-Strawberry-like appearance - common (due to gallbladder cholesterolosis).
- Small ridges (microvillus architecture) + yellow.
  - Normal gallbladder mucosa = smooth, green.
+/-Congestion/erythema.
+/-Wall thickening - typically ~ 6-7 mm.^[1]

Note:

Wall thickening (due to congestion/edema) is the important gross finding in acute cholecystitis.
Wall thickenss greater than 10 mm should raise the suspicion of malignancy.^[1]

Microscopic

Features:^[2]

Thickening of the gallbladder wall - due to fibrosis/muscular hypertrophy - key feature.
Chronic inflammatory cells - usu. "minimal".
- Lymphocytes - most common.
Rokitansky-Aschoff sinuses - common.^[3]
- Entrapped epithelial crypts -- pockets of epithelium in the wall of the gallbladder.
+/-Foamy macrophages in the lamina propria (cholesterolosis of the gallbladder).

DDx:

Gallbladder cholesterolosis and chronic cholecystitis.
Gallbladder adenomyoma.
Acute cholecystitis - more inflammation, lack Rokitansky-Aschoff sinuses, +/-mucosal erosions.
Cholecystectomy for gallstone pancreatitis - intraepithelial neutrophil clusters common, history essential.
Intestinal metaplasia of the gallbladder - goblet cells present, may be focal.
Gallbladder adenocarcinoma.

Sign out

GALLBLADDER, CHOLECYSTECTOMY: 
- CHRONIC CHOLECYSTITIS. 
- CHOLELITHIASIS.

Without stones

GALLBLADDER, CHOLECYSTECTOMY: 
- CHRONIC CHOLECYSTITIS. 
- NO GALLSTONES IDENTIFIED.

Liver present

GALLBLADDER, CHOLECYSTECTOMY: 
- CHRONIC CHOLECYSTITIS. 
- CHOLELITHIASIS.
- SMALL AMOUNT OF LIVER WITHOUT APPARENT PATHOLOGY.

GALLBLADDER, CHOLECYSTECTOMY:
- CHRONIC CHOLECYSTITIS WITH MILD CHOLESTEROLOSIS.
- CHOLELITHIASIS.
- SMALL AMOUNT OF LIVER WITH CAUTERY/CRUSH ARTIFACT.

Micro

The sections shows gallbladder wall with Rokitansky-Aschoff sinuses and a moderate mixed inflammatory infiltrate predominantly consisting of lymphocytes. No nuclear atypia is seen.

Post-cholecystostomy tube

The sections shows gallbladder wall with edema, a moderate mixed inflammatory infiltrate (predominantly consisting of lymphocytes and plasma cells), and mucosal erosions. Reactive fibroblasts and hemosiderin-laden macrophages are present. No significant nuclear changes are seen. One benign lymph node is present.
