[Histopathological study of gastric polyps. A report of 65 cases].
In a retrospective study of the specimens of gastric polypectomy, carried out between January 1992 and December 2002, we analysed the demographic and histological aspects of 65 polyps. This study revealed hyperplastic polyps in 66%, adenomatous lesions in 9.2%, Peutz-Jeghers polyps in 7.7%, inflammatory fibroid polyps in 6.15%, two cases of focal foveolar hyperplasia (3%), two cases of Brunner's gland heterotopia (3%), 1 pancreatic heterotopia (1.5%), 1 fundic gland polyp (1.5%) and 1 carcinoid tumor (1.5%). All adenomas and two Peutz-Jeghers polyps include intraepithelial neoplasia. Moreover, we identified a case of Brunner's gland heterotopia, which contain a focus of plane tubular adenoma with high-grade intraepithelial neoplasia. Other lesions were found within the polyps or into the surrounding gastric mucosa, such as intestinal metaplasia and Helicobacter Pylori gastritis. This work allowed us to recommend complete removal of gastric polyps and the realization of biopsies of the nonpolypoid gastric mucosa in the search of intraepithelial neoplasia or other lesions with malignant potential.
