| Περιγραφή: | In recent years scanning electron microscopy has been used in gastric biopsy studies, contributing to better recognition of intestinal metaplasie and carcinoma, as a complement to light and transmission electron microscopy. During the second half of 1983, 53 cases of gastric carcinoma were diagnosed at the Departament of Pathology of Hospital Mexico, of which six were studied ultrastructurally. A pattern similar to that of intestinal epithelium was found in cases of intestinal metaplasia. Well differentiated adenocarcinomas showed marked tumor cell proliferation with irregular "projections". In poorly differentiated carcinomas, changes were limited to areas where tumor cells invaded the epithelial surface. In summary, scanning electron microscopy is of great help in research and diagnosis of pathologic changes occuring in mucosal surfaces. |
