Gastrointestinal stromal tumors are neoplasias originated in the mesenchymal tissue of the gastrointestinal tract wall. It has been stated that cells originating these tumors are the Cajal´s interstitial cells, the digestive tract pacemaker, that are located in he Auerbach´s myoenteric plexus and answer to CD117, c-KIT oncogen. They may occur at any age but have an incidence peak during the sixth decade of life. The most common location is the stomach. There is a variety of sizes, from few millimeters to 20 cm or more. The case of a 56-years-old patient is presented in this work; he was admitted in the territorial hospital of Colon for presenting a high digestive bleeding in a melena form. Laboratory tests, imagine studies (contrasted Rx of stomach and duodena, abdominal ultrasound and CAT) and high digestive endoscopy were made.  It was proved the presence of a 5 cm polypoid tumor in the gastric pre-pyloric region. It was surgically operated and the final results of Pathologic Anatomy showed a gastrointestinal stromal tumor of low level malignancy.
