title: [Is vesicular cholesterolosis a particular anatomo-clinical form of cholesterol lithiasis? Apropos of a case of cholesterol polyp manifested by an acute complication].
abstract: A case of cholesterolic polyp, revealed by the formation of an infundibulo-cystic enclave, is reported, the polyp having the appearance of a cholesterolic calculus, but a pediculated one, and one acting as a calculus. The extreme rarity of this complication is emphasized. Despite the frequency of associated lithiasis, the cholesterolosis are included in a different framework from lithiasis, that of the cholecystoses that on histology show typical pure parietal lesions without inflammation. Findings in this atypical case suggest possible common pathogenic factors for the two affections, and raise a proposal for inclusion of cholesterolosis within the nosologic framework of lithiasis.
