Abstract

To determine the prevalence of goblet cell metaplasia in endocervical and endometrial adenocarcinomas by histochemial staining and to investigate the most sensitive histochemical staining method to detect this metaplasia, a total of 90 tissue blocks representing 30 non-neoplastic cervix, 30 non-neoplastic endometrium, 30 endocervical and endometrial adenocarcinoma cases were obtained for histochemical staining with Toluidine Blue (TB), Methylene Blue (MB), Mucicarmine (MUC), Periodic Acid Schiff before and after Diastase digestion (PAS, PAS-D), Alcian Blue pH 2.5 (AB), and Periodic Acid Schiff after Alcian Blue pH 2.5 (PAB). The cases were blinded and evaluated by a pathologist [NHO] for the presence of goblet cell metaplasia, the amount of goblet cells present and the histochemical differentiation of the goblet cells compared with its surrounding glandular epithelium. Goblet cell metaplasia was present in 2 out of 30 cases in non-neoplastic cervix, 0 out of 30 cases in non-neoplastic endometrium, 7 out of 15 cases in endocervical adenocarcinoma and in 2 out of 15 cases in endometrial adenocarcinoma. Relatively few goblet cells were seen in endometrial adenocarcinoma, few to moderate amounts were seen in endocervical adenocarcinoma and relatively more goblet cells were seen in non-neoplastic cervix. The differentiation of the goblet cells with its surrounding glandular epithelium was moderate to strong in non-neoplastic cervix and endocervical adenocarcinoma, while the differentiation in endometrial adenocarcinoma was weak to moderate. The various staining methods showed differences in presence, amount and differentiation of the goblet cells. Goblet cell metaplasia of the reproductive organs is not as rare as previously reported. There was no statistical difference in presence, amount and differentiation of goblet cells according to the various cases. The must optimum staining methods for staining goblet cells in non-neoplastic cervix, endocervical adenocarcinoma and endometrial adenocarcinoma were PAS, PAS-D and AB.
