Ceroid granulomas of the gallbladder.

The authors report two cases of ceroid-containing granulomas of the gallbladder, an entity not previously reported in the American medical literature. They postulate that in some cases of chronic cholecystitis, bile provides the substrate for the formation of ceroid within histiocytes. The ceroid granulomas were incidental findings associated with chronic cholecystitis and cholelithiasis.
