title: Intraductal carcinoma (carcinoma in situ) of the pancreas with microinvasion.
abstract: We report a case of predominantly intraductal carcinoma of the pancreas with microscopic foci of invasive carcinoma in a patient with chronic pancreatitis. In this article, we discuss the pathologic and prognostic features of pancreatic carcinoma in situ. This entity is probably overlooked due to a number of reasons, including the fact that, in most cases, pancreatic ductal carcinomas are extensively infiltrative at the time of surgical removal; the atypical epithelial changes in the intraductal carcinoma had been overlooked in the presence or absence of an invasive component; epithelial changes may be missed due to insufficient sampling; and last, the differentiation with atypical epithelial hyperplasia is a subjective matter. Intraductal carcinoma of the pancreas is a distinct pathological entity with characteristic morphologic changes restricted to the ductal epithelium, bearing important prognostic implications.
