The foremost symptoms of small bowel tumors are bleeding, obstruction, and perforation. A 61-year-old female was admitted with abdominal pain, nausea and vomiting lasting for 2 days. Computed tomography investigation revealed a mass of small bowel in 2x5 cm size. On exploration a perforated tumor originated from a jejunal segment 45 cm distal from the ligament of Treitz was identified. Segmental resection and primary anastomosis were performed. The histopathologic and immunohistochemical investigation demonstrated gastrointestinal stromal tumor arising from small bowel. Immunohistochemically, the neoplastic cells strongly stained with CD117, desmin, and CD34 antibodies. Postoperatively, the patient was treated by oral administration of 400 mg/day of imatinib. Surveillance abdominal computed tomography scan at six months was unremarkable. Physicians should be kept this rare entity in mind for prolonged survival and accurate treatment including oncologic surgery.en10.4328/JCAM.497info:eu-repo/semantics/openAccessGastrointestinal Stromal TumorsSmall Bowel TumorsAcute AbdomentheArticle33341343N/AWOS:000215547400026137365
