Gallbladder inflammatory polyps

Gallbladder inflammatory polyps are a benign subtype of gallbladder polyps, representing ~10% of all polyps. They appear as a result of chronic inflammation (chronic cholecystitis).

For further details, please refer to the parental article on gallbladder polyps.

Pathology

Gallbladder inflammatory polyps are thought to develop from chronic inflammation, with deposition of cholesterol in the gallbladder wall and mucosal irritation, leading to a fibrous reaction .

There is no evidence that they are a premalignant lesion .
