| umls-concept:C1332460 | skos:definition | NCI: An adenocarcinoma arising from Barrett metaplastic epithelium in the esophagus. There is evidence supporting the idea that the Barrett adenocarcinomas develop through a stepwise progression through intestinal metaplastic epithelium to epithelial dysplasia to malignancy. Adenocarcinomas arising in the setting of Barrett esophagus are typically papillary and/or tubular. In terms of grading, they are well or moderately differentiated adenocarcinomas. -- 2002 | lld:umls |
