bile duct adenoma
Thursday 2 September 2010
On account of this similarity in phenotype and their frequent close association with a large caliber bile duct, it was earlier suggested that bile duct adenoma represent a peribiliary gland hamartoma.
The distinguishing feature of so-called bile duct adenoma is their display of the same phenotype as pyloric gland metaplasia. They develop as a localized biliary healing response equivalent to the function of a peribiliary gland or pyloric gland metaplasia in the foregut.
