Extensive Rokitansky-Aschoff sinuses in a 64 year ood woman. A. Extending from a benign, chronically inflamed plicae are Rikitansky-Aschoff sinuses. Note their travel in between muscle bundles can be recognized as continuity to the surface. B. In between the gall stone at lower left and the lymphoid aggregate at upper right lies the gallbladder wall. Note the longitudinal extensions of the Rokitansky-Aschoff sinuses, as well as the ballooning outside the wall at lower right. C. The mucosa shows extensive reactive branching. Note again the predominant extension between muscle bundles, recognizable by the stroma about the sinuses, some of which are branched, pushing the muscle wall aside. There is no desmoplasia, but some gallbladder adenocarcinomas show little recognizable desmoplasia. D. The focus on the right is difficult to identify as lying between muscle bundles. The triple parallel tubules argue against neoplasia. The lack of cancerous nuclear change is important as well. | |||

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 (biliary colic).
- 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.
- Small ridges (microvillus architecture) + yellow.
- +/-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.

Extensive Rokitansky-Aschoff sinuses in a 64 year ood woman. A. Extending from a benign, chronically inflamed plicae are Rikitansky-Aschoff sinuses. Note their travel in between muscle bundles can be recognized as continuity to the surface. B. In between the gall stone at lower left and the lymphoid aggregate at upper right lies the gallbladder wall. Note the longitudinal extensions of the Rokitansky-Aschoff sinuses, as well as the ballooning outside the wall at lower right. C. The mucosa shows extensive reactive branching. Note again the predominant extension between muscle bundles, recognizable by the stroma about the sinuses, some of which are branched, pushing the muscle wall aside. There is no desmoplasia, but some gallbladder adenocarcinomas show little recognizable desmoplasia. D. The focus on the right is difficult to identify as lying between muscle bundles. The triple parallel tubules argue against neoplasia. The lack of cancerous nuclear change is important as well.
Chronic cholecystitis with reactive epithelial atypia in a 92 year old. A. Lymphoid follicles are associated with chronically inflamed plicae. B. Neutrophils lie within cytoplasm of epithelium. Nuclei show variability in size and, to a lesser degree, shape. Some cells are multinucleated. Polarity is generally, but not always, preserved, with most nuclei at the base of the cell, with the longer nuclear dimension, when the nucleus is not round, being perpendicular to the luminal surface. C. Monoclonal CEA stains neutrophils, but not epithelial cells. D. CD10 stains the luminal surfaces of epithelial cells, a finding that militates against dysplasia.

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.
