Xanthogranulomatous cholecystitis, abbreviated XGC, is an uncommon pathology of the gallbladder.
General
- Uncommon ~ 1-9%.[1][2]
- Approximately 2% in one series of 724 gallbladders.[3]
- May be confused (clinically) with gallbladder carcinoma.[1][4]
Gross
Features:[5]
- Wall thickening ~ 90% of cases.
- Gallstones ~ 70% of cases.
- +/-Infiltration of surrounding tissues (liver, fat).
Imaging:
- Hypo-attenuated nodules in the gallbladder wall.[5]
Microscopic
Features:[3]
- Granulomas.
- Lipid-laden macrophages.
- +/-Cholesterol clefts.
- Inflammatory cells.
- Fibrosis.
