Although gastrointestinal stromal tumors (GISTs) comprise less than 1% of all gastrointestinal (GI) tract tumors, they are the most common mesenchymal tumors of the GI tract. Gastrointestinal stromal tumors can occur anywhere along the GI tract, but the stomach and small intestine are the most frequently involved sites. Gastrointestinal stromal tumors are frequently asymptomatic, and one-third of all cases are found incidentally. Endoscopy, endoscopic ultrasonography, and computed tomography are useful tools in the diagnosis. Endoscopic mucosal resection, endoscopic submucosal dissection, laparoscopic endoscopic cooperative surgery, and surgery with either laparoscopic or open approaches are treatment modalities for GISTs. An R0 resection is the principle surgery. Imatinib is the main medical agent used in the adjuvant or neoadjuvant treatment of GIST. We present a 65-year-old woman with an asymptomatic GIST that arose from a gastric polyp treated via endoscopic polypectomy.
