Obstruction of the bile duct by a papillary adenoma of the gallbladder.

A case of papillary adenoma of the gallbladder unassociated with cholelithiasis and showing detachment of part of the growth with obstruction of the common bile duct is described. One the basis of a search of the literature, it would appear that this is the first time such a case has been reported. The bibliography is discussed and a distinction drawn between this kind of adenoma and other benign tumors of the gallbladder.
