intestinal metaplasia of the gallbladder mucosa

Synopsis
isolated or small clusters of mature goblet cells
possible argyrophil and argentaffin cells
less frequently, Paneth cells and gland-like structures similar to colonic crypts.
possible pseudopyloric glands and superficial gastric-type epithelium
The presence of gut endocrine cells and Paneth cells in the pseudopyloric glands suggests that these glands are also an integral component of intestinal metaplasia of the gallbladder.
Intestinal metaplasia in the gallbladder is strongly associated with expression of caudal-related homeobox transcription factor CDX2.
Cholelithiasis probably induces the appearance of a stem endodermal cell that, in turn, may differentiate into cells with mature intestinal or gastric phenotypes.
