[Eosinophilic cholecystitis: an infrequent cause of cholecystectomy].

Eosinophilic cholecystitis is a rare form of cholecystitis. Histologically, it is characterized by a dense, transmural leukocyte infiltrate composed of more than 90% eosinophils. The etiology remains obscure, although it had been associated with allergies, parasites, hypereosinophilic syndromes, eosinophilic gastroenteritis, cholelithiasis, and acalculous cholecystitis. Here we report an eosinophilic cholecystitis gallstone-associated case, the only one with this histopathologic diagnosis among 5,537 cholecystectomies made in our hospital in the last years.
