Xanthogranulomatous cholecystitis is a benign chronic inflammation of the gallbladder that can morphologically mimic carcinoma. In severe cases, the diagnosis is made intraoperatively using frozen section histology and pathologic consultation. Once the diagnosis of xanthogranulomatous cholecystitis is confirmed, cholecystectomy should be performed. Occasionally, the inflammatory reaction and fibrosis within the gallbladder is so severe that conventional cholecystectomy is unsafe. In these instances, a subtotal cholecystectomy is required.
