Abstract
Background Gastrointestinal stromal tumors are mesenchymal neoplasms of the gastrointestinal tract, arising from the muscular layer. Revent immunohistochemical studies have shown that up to 94% of GISTs express 117, and 60–70% of GISTs stain for CD 34. GISTs account for 1% of all malignant tumors of gastrointestinal tract; they arise from stomach in the 40–60% of cases whereas they account only for 3% of gastric malignant neoplasms. GISTs can occur at any age but onset most commonly in the sixth and the seventh decades of life.
