Idiopathic eosinophilic cholecystitis with cholelithiasis: a report of two cases

Abstract

Eosinophilic cholecystitis is a rare entity diagnosed on the basis of classical presentation of cholecystitis with presence of more than 90% eosinophilic infiltration within the gall bladder. The etiology of eosinophilic cholecystitis still remains obscure. However it is frequently associated with other more severe diseases like hypereosinophilic syndrome, eosinophilic-myalgia syndrome, parasitic infestations, few herbal medicines and certain drugs. We report two cases who presented with gall stone disease, which on histopathological evaluation was diagnosed as eosinophilic cholecystitis. Retrospective analysis of their case histories and investigation did not reveal any known etiology. These cases are being reported because of their rarity and to highlight the importance of complete workup to rule out other associated disorders that may be a manifestation of a more severe disease.
