[Intestinal metaplasia in glandular and cystic formations and human urothelial adenocarcinoma]. 1979

N M Anichkov, and A A Nikonov, and I Veresh

Thirteen cases of inflammatory changes in the urothelium with formation of glandular and cystous structures, 3 cases of glandular metaplasia in transitional cell carcinoma and 8 adenocarcinomas were examined. In inflammation, initial glandular and cystic structures have signs of somehow incompleted metaplasia of the intestinal type. In advanced glandular structures metaplasia is completed and urothelium acquires similarity in the structure and properties of the produced mucus with the large intestine epithelium (numerous goblet, cylindrical limbic and non-differentiated cells, prevalence of argentaffinic cells over argirophilic, lack of Panet cells, secretion of sulfomucines). In loci of glandular metaplasia of transitional cell carcinoma there are also signs of somehow incompleted intestinal differentiation. Most typical variants of urothelial adenocarcinoma are quite similar to glandular carcinoma by the structure and properties of the produced mucus.
