title: Diffuse papillomatosis of the gallbladder complicated with tuberculosis.
abstract: A rare case of diffuse papillomatosis of the gallbladder complicated with tuberculosis is reported. The mucosa of the gallbladder displayed a diffuse papillary pattern composed of excrescences that varied in size and height. The proliferative glands contained many Paneth cells, and the diffuse papillomatosis appeared to be derived from metaplastic-type epithelium. Tuberculous granulomas were observed in the serous layer of the gallbladder. The relationship between diffuse papillomatosis and tuberculosis of the gallbladder is discussed.
