A case of idiopathic eosinophilic cholecystitis / 대한내과학회지

Eosinophilic cholecystitis is a rare form of cholecystitis that is clinically indistinguishable from the predominant form of calculous cholecystitis. Histologically, it is characterized by a dense, transmural leukocyte infiltrate composed of more than 90% eosinophils. A 60-year-old woman complained of right upper quadrant pain. She had no allergic or medicine history. An abdominal CT scan revealed thickened gallbladder wall but no cholelithiasis, and a cholecystectomy was performed. Histologic examination showed transmural eosinophilic infiltration of the gallbladder wall.
