ABSTRACT
Gastrointestinal stromal tumors (GIST) constitute the majority of mesenchymal tumors involving the gastrointestinal tract. It is estimated that there are 2500 to 6000 cases per year in the U.S. Although the clinical presentation varies depending on the tumor size and anatomical location, most tumor are found incidentally at the time of endoscopic or radiologic imaging. Gists arise most frequently in the stomach (60-70%), followed by the small intestine (20-25%), colon and rectum (5%), and esophagus (‹5%). Most Gist are sporadic and, in 95% of cases solitary. Most patients with GISTs present in the fifth to the seventh decades of life, and these tumors are equally distributed between the genders. Symptoms of these lesions include pain and gastrointestinal bleeding, with abdominal mass a frequent finding. Surgical resection remains the treatment of choice for GISTs. However, despite complete surgical resection, the majority of patients (76%) will suffer local recurrence. This article documents two cases of patients with GIST with different clinical features. This is a 26 year old female patient with an abdominal mass as a sign of submission and the other 67 years male patient who presents with gastrointestinal bleeding as the initial manifestation.REFERENCES
