Does Cytokeratin7/20 immunoreactivity help to distinguish Barrett's esophagus from gastric intestinal metaplasia? Results of a prospective study of 75 patients
Barrett's esophagus is a recognized risk factor for the development of esophageal dysplasia and carcinoma. Unfortunately, gastric incomplete intestinal metaplasia arising in Short Segment Barrett's esophagus can be indistinguishable histologically on hematoxylin/eosin stains. Distinct patterns of CK 7 and CK 20 immunohistochemical expression have been demonstrated to be both highly sensitive and specific for Barrett's esophagus, but have not been found in gastric metaplasia. The aim of our study was to test whether immunostaining with CK 7/20 helps to distinguish between Barrett's epithelium and gastric incomplete metaplasia. Cases of long segment Barrett's esophagus, short segment Barrett'…
Der hyperplastische Polyp des Magens - eine Präkanzerose?
In general, hyperplastic polyps of the stomach are regarded as benign lesions. Still there is the chance to find carcinomas within them as documented in this case report. This finding can be interpreted as an incidental appearance. At the moment there are no standardized guidelines regarding diagnostics and therapy of gastric hyperplastic polyps. Referring to a short review of the literature endoscopic snare polypectomy seems to be a reasonable therapeutic option of hyperplastic polyps with a size of 0.5-1 cm. Although it is possible to determine the histology by forceps biopsy, it is possible to be misled by missing areas of focal carcinomas. Complications after polypectomy are rare and of…
