Adenocarcinoma arising from heterotopic pancreas at the third portion of the duodenum

Abstract: A 62-year-old Japanese man presented to our hospital with a history of weight loss of 6 kg in 4 mo. Imaging examinations revealed a tumor located on the third portion of the duodenum with stenosis. We suspected duodenal carcinoma and performed pancreas-preserving segmental duodenectomy. Adenocarcinoma arising from a heterotopic pancreas at the third portion of the duodenum was finally diagnosed by immunohistochemical staining. Malignant transformation in the duodenum arising from a heterotopic pancreas is extr… Show more

“…The reported incidence of ectopic pancreas ranges from 0.25% to 1.2% [5], mostly found in duodenum (29.3%), stomach (27.4%), jejunum (15.7%), ileum (5.9%), Meckel's diverticulum (5.1%), and gallbladder (2.7%) [6]. Chances are that similar pathological changes such as acute pancreatitis or cyst formation may occur in ectopic pancreas, but dysplasia and malignant degeneration rarely develops [7].…”

“…Такой подход безопасен в плане рецидива, так как из-за длительного воспаления в кистах нет эпителия. Абсолютно необходимо для исключения злокачественного процесса выполнять интраоперационную биопсию резецированного участка ДПК [33][34][35].…”
