Gastrointestinal stromal tumors (GIST) have become a well-defined entity and its classification is no more equivocal, but GIST of duodenum is rarely diagnosed. We report a case of a patient presented with only mild epigastric discomfort. The upper gastrointestinal (GI) endoscopy demonstrated an extrinsic compression of second part of duodenum. Thereafter, CT and MRI of abdomen revealed an exophytic mass emerging from the second part and third of duodenum. The patient underwent a wedge resection of tumor, and the histopathology of the mass confirmed the diagnosis of duodenal stromal tumor. The patient was treated with adjuvant imatinib chemotherapy with no sign of local recurrence after six months of follow up.
