The occurrence of heterotopic pancreatic tissue in the abdomen has been well described and is of more than occasional frequency. It has further been noted that this tissue may be subject to most of the pathologic changes ascribed to the pancreas itself; however, malignant transformation in pancreatic heterotopia has only rarely been described. We encountered such a case occurring in a duodeno-pyloric focus in an 82-year-old woman; the lesion was rapidly fatal. Int J Surg Pathol 2(1):37-42, 1994
