ABSTRACT: Introduction: Colorectal gastrointestinal stromal tumors (GISTs) mesenchymal tumor is very uncommon. GISTs effect mostly on the stomach and small intestine and rarely occur in the colon, rectum and esophagus, that originating from precursors of the interstitial cells that originate of Cajal. The symptoms of gastrointestinal stromal tumor depend on the site and size of the tumor, and may include abdominal pain, gastrointestinal bleeding or signs of obstruction; small tumors may, however, be asymptomatic. Some of the patients with gastrointestinal stromal tumor have bloody stools, obstruction and abdominal pain as the commonest manifestation. Immunocytochemical staining for CD117 is helpful in confirming the diagnosis. Case presentation: We report 3 new cases of GISTs: two occurred at the rectal and the other at descending Colon. Two cases are over 50 years of age and, and all cases the chief complain of bowel obstruction, abdominal pain in two cases, and one case with anemia and urine retention. All the patients were operated and were permormed pathology examinatiom. All case ware positive result for immunocytochemical staining CD117. All cases we had presented had size more than 5 cm are considered as unfavorable prognostic factors to Fletcher criteria, all patients scheduled for chemotherapy with Glivec but just one patient continued to used Glivec. Post surgery follows up one patient post milles with urinary incontinence complaints found and that patients are trained to CIC (intermittent catheterization). Conclusion: Colorectal gastrointestinal stromal tumors are very rare and can present as mass abdomen. Resection and chemotherapy are the treatment of choice.
