Abstract
Heterotopic pancreas (HP) is a rare condition, is commonly asymptomatic and found incidentally at autopsy or during abdominal surgery. HP is usually found in the upper gastrointestinal tract, particularly in the stomach, duodenum and jejunum. Mesenteric heterotopic pancreas (MHP) has been rarely described in the literature, and there has been no reported case under ten years of age. We report a unique case of a 7-year-old African boy who presented with clinical appendicitis and intraoperatively was found to have a necrotic nodular mass in the jejunal mesentery which required segmental small bowel resection. Histology revealed mesenteric heterotopic pancreas with normal pancreatic tissue. As pre-operative diagnosis of MHP is difficult; we encourage a heightened awareness of this condition as a differential diagnosis in children presenting with abdominal pain and an inflammatory mass, which will subsequently aid in the management of these patients.
