Intestinal metaplasia of the stomach and esophagus: an immunohistochemical study of 60 cases including comparison with normal and inflamed intestinal mucosa

Popis výsledku v původním jazyce

Recently, a new classification of intestinal metaplasia (IM) using immunohistochemical mucin markers was proposed. Two following types of IM were defined: (1) a mixed gastric and intestinal type also called incomplete IM; (2) a purely intestinal type, also called complete IM. We present a series of 30 cases of gastric IM and 30 cases of IM of the esophagus, using this new classification. In all gastric cases, IM developed in the mucus-neck region in the form of incomplete IM. Toward the mucosa surface,it matured gradually into complete IM. This maturation showed a gradual reduction of both foveolar mucin MUC5AC and pyloric gland mucin MUC6. In two of 30 cases, IM was of the incomplete hyperproliferative type. In one case, focal high-grade adenomatousdysplasia was found in the incomplete IM. In the esophageal cases, IM was found in inflamed cardiac-type mucosa, and it was usually of the incomplete type, with almost diffuse positivity for MUC5AC and with rare positivity of MUC6. The go
