RESUMO
Introduction: Gastrointestinal tumor (GIT) is an uncommon gastrointestinal tumor most commonly arising in the stomach. Duodenum is an uncommon site accounting for only about 3-5% of cases. Case presentation: In this case report, we present a case of high-risk duodenal GIST and review its management strategies. Discussion: An abdominal mass and gastrointestinal (GI) bleeding are its usual presentation, however it may be lost among the long list of differentials of an abdominal mass and GI bleeding, if a high index of suspicion is not maintained. Surgery, with or without tyrosine kinase inhibitors like imatinib mesylate, has been the cornerstone in management of GIST. Conclusion: This case underlined the importance of duodenal GIST as a cause of GI bleed and abdominal mass as well as shone light upon historical developments, current updates and managements of GISTs.
