Abstract

We report a case of adenocarcinoma of aberrant pancreas in the stomach. A 58-year-old woman consulted our hospital for repetitive vomiting after meals. Endoscopic examination revealed pyloric stenosis, but there was no evidence of malignancy. Endoscopic ultrasonography of the pylorus showed preservation of its layered structure and no evidence of a tumor. When balloon dilatation of the pyloric ring on two occasions failed to improve the symptoms, laparotomy was performed. Since preoperative pathological examination of the mucosa in the pylorus revealed no evidence of malignancy, pylorectomy was performed. Histopathological examination revealed adenocarcinoma cells adjacent to aberrant pancreas with acinar cells and pancreatic ducts present between the muscular layer of the mucosa and the subserosa, and a diagnosis of adenocarcinoma of aberrant pancreas in the stomach was made. Distal gastrectomy was performed later, and histopathological examination of the surgical specimen revealed No. 5 lymph node metasasis. The final pathological findings were pT2, pN1, sH0, sP0, cM0, fStage II.
