Core Tip
Core tip: Based on all abdominal surgeries, the incidence of heterotopic pancreas ranges from 0.25% to 1.2%. The frequency of malignant transformation ranges from 0.7% to 1.8% among all heterotopic pancreas cases. Malignant transformation arising from a heterotopic pancreas is extremely rare. The most common location of malignancy is the proximal duodenum at the first and descending portion. In this paper, we report the case of a patient with weight loss who was diagnosed as having an adenocarcinoma arising from a heterotopic pancreas, at the third portion of the duodenum, with a review of the literature.
