An unusual case of acute cholecystitis with amyloidosis: A case report and literature review

Abstract

We present an extremely rare case of amyloid A (AA) deposition in the gallbladder and review the literature on similar cases. The patient was a 76-year-old man who had been diagnosed with mild bronchiectasis three years previously, who was admitted to the hospital with right upper quadrant pain and fever. Computed tomography revealed swelling and wall thickening of the gallbladder with a small gallstone. The patient was diagnosed with acute cholecystitis and cholelithiasis and underwent open cholecystectomy. A postoperative histological examination revealed extensive AA deposition in the gallbladder wall. Thus, the definitive diagnosis was acute cholecystitis with AA amyloidosis.
