BACKGROUND The differential diagnosis of abdominal masses is somewhat troublesome,especially when there is a malignancy to be evaluated.We report herein a unique case of gastric adenocarcinoma concurrent with a pancreatic schwannoma.Correct assessment of intraoperative findings is essential for adequate tumor staging and to decide the proper management of a concurrent pancreatic lesion.CASE SUMMARY Computed tomography scan performed for gastric cancer staging revealed a solid and cystic pancreatic mass that had no signs of local invasiveness.Surgical resection of the pancreas was decided preoperatively since a radical approach of the gastric tumor could be performed.There were no signs of distant metastases,and the large pancreatic mass was in contact with the posterior gastric wall.Histopathological study revealed a pancreatic schwannoma,which is an uncommon neoplasm that arises from Schwann cells around peripheral nerves.CONCLUSION Therefore,pancreatic masses deserve special attention regarding the differential diagnosis in patients with gastric cancer.The presence of a large pancreatic mass should not preclude the potentially curative intent of the gastric cancer treatment.
