Abstract:
The gastrointestinal stromal tumor (GIST) is a mesenchymal tumor of the digestive tract showing differentiation along the line of interstitial cell of Cajal. The most GISTs in the stomach generally show the appearance of submucosal tumors. It is rare for GISTs to appear as a pedunculated polypoid lesion on endoscopy. We experienced a case of a 51-year-old man who had a pedunculated polypoid GIST. He was admitted to our hospital for nausea, vomiting, melena and severe anemia (hemoglobin 3.4 g/dL, hematocrit 10.8%). An upper endoscopy showed gastroduodenal intussusception due to a pedunculated polypoid mass. This report presents a rare case of endoscopically proven gastroduodenal intussusceptions due to pedunculated polypoid GIST in the stomach.
