Abstract

GISTs are rare, with only around 5,000 cases diagnosed annually in the United States. However, these tumors are the most common mesenchymal neoplasm in the gastrointestinal (GI) tract. 5%-15% of GISTS arise in the colon and rectum. Most GISTs are diagnosed incidentally on imaging, endoscopy, or during a surgical procedure.
