Eosinophilic Cholecystitis as an Atypical Etiology of Biliary Colic: A Case Report and Review of the Literature.

Eosinophilic cholecystitis (EC) is an uncommon cause of acute cholecystitis; the clinical presentation is indistinguishable from other types of cholecystitis, and the diagnosis is made by histopathology study. We present the case of a 73-year-old male patient with right hypochondrial abdominal pain suggestive of symptomatic cholelithiasis. There were no significant findings at the blood workup or physical examination; he underwent a cholecystectomy and was later diagnosed with eosinophilic cholecystitis by histopathology. EC may be associated with some other systemic conditions, such as eosinophilic granulomatosis, eosinophilic ascites, or parasitosis, which will require specific management.
