BACKGROUND: Gastrointestinal stromal tumor (GIST) represents an uncommon form of neoplasm. The combination of duodenal GIST and gastrointestinal bleeding consist of a rare presentation for such tumors. AIM: To report duodenal GIST case complicated by gastrointestinal bleeding. CASE REPORT: A 64-year-old male was admitted presenting abdominal pain, melena and a palpable mass in epigastrium and left upper abdomem regions. CT scan reveled a thick wall tumor containing cystic content in the pancreatic tail topography. At emergency laparotomy, a tumor in the fourth portion of the duodenum presenting colonic invasion in splenic flexure was found. En-bloc resection of the tumor was carried out, included the fourth portion of the duodenum and the transverse and descending colon, without postoperative complications. Immunohistochemical staining of the resected specimen confirmed the diagnosis of duodenal GIST with colon wall invasion. CONCLUSION: Gastrointestinal hemorrhage is one of the possible complications of GIST. Early surgical treatment is the only effective therapeutic option to avoid severe complications of hemorrhagic shock.
