Ectopic pancreas (EP) is the relatively uncommon presence of pancreatic tissue outside the normal location of the pancreas. This condition is usually asymptomatic and rarely complicated by pancreatitis and malignant transformation. A few cases of neoplastic phenomena that developed from EP into the duodenal wall are described in the literature. Herein we report a case of gastric outlet obstruction due to adenocarcinoma arising from EP of the duodenal wall. The patient underwent a Whipple's procedure and had an uneventful post-operative recovery. Traditional imaging studies are often inconclusive in the definitive diagnosis, whilst endoscopic ultrasonography and guided biopsy may aid accurate pre-operative diagnosis. Diagnostic uncertainty warrants surgical exploration and if necessary extended resection is indicated.
