Context: Cystic dystrophy of the digestive wall, a rare but well-known complication of heterotopic pancreas when it is located in the duodenum, has been mainly described in adult series. Cystic dystrophy of the heterotopic pancreas within the gastric wall has been reported in only six adult cases. To our knowledge, no pediatric case has been described.
Case report: We report a 15-year-old boy surgically treated for cystic dystrophy located in the antrum, complicated by an intracystic hemorrhage and fistulisation into the stomach.
Conclusion: The diagnosis of heterotopic pancreas must be considered in case of submucosal cystic-gastric lesions, even in pediatric cases. Although the surgical approach is not systematic, it is recommended when cystic dystrophy is symptomatic (e.g., occlusion or hemorrhage).
