    Abstract:
    CONTEXT: Heterotopic pancreatic adenocarcinoma is a rare finding at laparotomy. Herein we present the case of a patient with malignant transformation of a heterotopic pancreas located in the fourth portion of the duodenum. CASE REPORT: A 79-year-old woman was admitted to the surgery service with complaints of early satiety and abdominal fullness progressively worsening over the previous two years. A computed tomography scan of the abdomen and an upper endoscopy revealed an obstructing mass in the fourth portion of the duodenum, biopsies were negative for carcinoma. A segmentectomy of the third and fourth portions of the duodenum was performed. Post-operative histology revealed malignant transformation of a heterotopic pancreas. The patient had an unremarkable postoperative recovery and was discharged home. CONCLUSION: In evaluation of patients with distal duodenal masses, we report that heterotopic pancreatic neoplasms should be considered in the differential diagnosis.
