MIRANDA, Florentino José; KALLAS, Daniel Carvalho; FALCO, Wilson De and RAVANINI, Laert Noel. Gastric Gastrointestinal Stromal Tumor (GIST). Rev. Col. Bras. Cir. [online]. 2008, vol.35, n.3, pp. 212-213. ISSN 0100-6991. http://dx.doi.org/10.1590/S0100-69912008000300016.
Gastrointestinal Stromal Tumor (GIST), despite rare, is the most common digestive tract mesenchymal tumor. Modern histogenesis studies have shown its stromal origin and not a muscular origin as it had been believed before. Diagnosis is made through immunohistochemical studies (CD- 117) and treatment is achieved with surgery followed by chemotherapy and has good results. The authors describe a case of gastric GIST discovered after upper gastrointestinal bleeding presentation, and treated successfully.
