Introduction:
Aberrant pancreas in the jejunum is a rare condition, and its malignant transformation is very unusual.
Case Report:
We presented a case in which jejunal carcinoma occurred in the aberrant pancreas. A 76-year-old woman was admitted to our hospital due to repetitive vomiting after meals. Radiology showed high obstruction in the proximal jejunum. Laparotomy revealed that the obstruction was a submucosal tumor. Partial resection of the jejunum including the tumor was performed. Histology showed that the tumor was made up of well-differentiated adenocarcinoma originating from aberrant pancreatic tissues.
Conclusion:
This was the tenth case of aberrant pancreatic carcinoma in the jejunum reported in literature.
