Incidental gastrointestinal stromal tumor at a gastroscopic polypectomy specimen: A case report and review of literature

Özet

Although gastrointestinal stromal tumors (GISTs) comprise less than 1% of all gastrointestinal (GI) tract tumors, theyare the most common mesenchymal tumors of the GI tract. Gastrointestinal stromal tumors can occur anywherealong 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, endoscopicultrasonography, and computed tomography are useful tools in the diagnosis. Endoscopic mucosal resection, endoscopic submucosal dissection, laparoscopic endoscopic cooperative surgery, and surgery with either laparoscopic oropen approaches are treatment modalities for GISTs. An R0 resection is the principle surgery. Imatinib is the mainmedical agent used in the adjuvant or neoadjuvant treatment of GIST. We present a 65-year-old woman with anasymptomatic GIST that arose from a gastric polyp treated via endoscopic polypectomy.
