Acute cholecystitis, abbreviated AC, is a relatively uncommon gallbladder pathology when compared to chronic cholecystitis. It is usually associated with gallstones and seen in older individuals.
General
- Less common than chronic cholecystitis.
- Usually due to gallstones.[1]
- Classically older individuals (50s and 60s) with a slight female predominance.[1]
Notes:
- Pathologic diagnosis very often discordant with clinical impression.[2]
Gross
Features:[1]
- Wall thickening - due to edema and hemorrhage.†
- Gallstone(s) - classically obstructing the gallbladder neck.
- +/-Mucosal erosions.
Note:
Microscopic
Features:[1]
- Edema.
- Hemorrhage.
- +/-Fibrin thrombi in small veins.
- +/-Mucosal erosions.
- +/-Neutrophils - useful
- +/-Reactive epithelial changes.[6]
Notes:
- May see activated fibroblasts.
DDx:
- Chronic cholecystitis - has less inflammation, fibrotic wall thickening/muscular hypertrophy, may have RK sinuses.
- Gallbladder adenocarcinoma.
- Intestinal metaplasia of the gallbladder.
- Eosinophilic cholecystitis - has >90% eosinophils.

Special types
Gangrenous cholecystitis
General:[7]
- Older.
- Clinically "sicker".
- Worse outcome than (acute) non-gangrenous cholecystitis.
Microscopic:

Necrosis of wall
Gallbladder, Cholecystectomy: - Acute cholecystitis with multiple mucosal erosions and focal necrosis of the gallbladder wall.
GALLBLADDER, CHOLECYSTECTOMY: - ACUTE AND CHRONIC CHOLECYSTITIS WITH MULTIPLE MUCOSAL EROSIONS AND FOCAL NECROSIS OF THE GALLBLADDER WALL.
Gangrenous cholecystitis
GALLBLADDER, CHOLECYSTECTOMY: - GANGRENOUS CHOLECYSTITIS. - CHOLELITHIASIS.
Gallbladder, Cholecystectomy: - Gangrenous (acute) cholecystitis with cholelithiasis.
Xanthomatous lymph node present
GALLBLADDER, CHOLECYSTECTOMY: - ACUTE CHOLECYSTITIS. - CHOLELITHIASIS. - BENIGN LYMPH NODE WITH NONNECROTIZING GRANULOMAS, XANTHOMATOUS APPEARANCE. - NEGATIVE FOR DYSPLASIA.
Micro
The sections show gallbladder wall with hemorrhage, and activated fibroblasts. The superficial mucosa has clusters of neutrophils.
Alternate
The sections show an inflamed gallbladder wall with hemorrhage, activated fibroblasts and focal necrosis. The mucosa is partially eroded. Abundant neutrophils and eosinophils are present. No significant nuclear changes are apparent.
