Abstract
Usually Gastric Mini Bypass procedure does not result in a pathology specimen. We present 2 case reports of benign mesenchymal tumours-one GIST (Gastro-Intestinal Stromal Tumour) and one Leiomyoma found in rare specimen received post mini gastric bypass surgery. In the first case no mass was detected by the surgeons and an extra part of gastric stump was removed and sent and in the second instance a mass was felt before anastomosis and was removed and sent. The detection of incidental tumors in such specimen require thorough gross examination followed by histopathological examination on Hematoxylin and Eosin (H&E) and immunohistochemistry slides for final diagnosis. Final report should include a comment on status of surgical margins and malignant potential of the tumor.
