Dr Sampurna Roy  MD


Mucosal hyperplasia of gallbladder may be seen in association with cholesterolosis and myomatosis or metachromatic leucodystrophy.

Villous and adenomatous hyperplasia are the two important types of mucosal hyperplasia of the gallbladder.

The mucosa in this condition is uneven and thickened.

Villous (papillary) hyperplasia:
