"Small intestinal type" and "colonic type" intestinal metaplasia of the human stomach, and their relationship to the histogenetic types of gastric adenocarcinoma.

Intestinal metaplasia in the non-tumour bearing parts of the gastric mucosa was demonstrated in 24 cases in a material consisting of 27 consecutive patients operated for carcinoma of the stomach. Two mucin histochemical types of intestinal metaplasia could be identified. 1) "Small intestinal type" which was present in all 24 cases, and which was by far the most dominating type. 2) "Colonic type" which occurred in small foci in the gastric mucosa of 11 cases, and which was significantly more frequent in stomachs bearing tumours of presumed intestinal histogenesis, than in those bearing tumours of presumed non-intestinal histogenesis.
