Core Tip
Core Tip: Ectopic pancreatic tissue is a congenital anomaly. Currently, only two anecdotal cases of malignant transformation of colonic ectopic pancreatic tissue have been described. We present a case of an 81-year-old patient with a primitive adenocarcinoma of the right colon, with ductal morphology and solid-predominant growth pattern. Carbohydrate antigen 19-9 value was above the normal values, and both pancreas and biliary tree were healthy. Benign ectopic pancreatic tissue was missing in the surgical specimen. This observation is suggestive of a complete degeneration of a rare colonic ectopic pancreatic tissue or, even more interesting, the first description of a primitive ductal adenocarcinoma of the colon.
