Intestinal, gastric body- and antral-type mucosal metaplasia in the gallbladder.

The material consisted of two intestinal, one gastric body-type and 14 antral-type cases of mucosal metaplasia in the gallbladder. Outside the mucosal areas mentioned, the epithelium of the gallbladder had undergone great changes. It usually consisted of goblet cells, enterochromaffin cells, superficial gastric-type epithelial islands and antral-type glands. Extensive areas contained non-sulphated acid mucin and neutral mucin. The areas of normal gallbladder epithelium were small.
