Primary mesenteric gastrointestinal stromal tumor presented with acute small bowel obstruction

Abstract

Primary mesenteric gastrointestinal stromal tumors may give rise to abdominal emergencies like bowel obstruction and should be considered in the differential diagnosis to reduce morbidity and mortality. The present study presents an unusual case of primary mesenteric gastrointestinal stromal tumor presenting with small bowel obstruction. A 44-year-old healthy male presented with abdominal pain for 2 days. Detailed examination revealed presence of a 4 × 4 cm mass in the small bowel mesentery with multiple small bowel loops adherent to it, together with their mesentery. The patient was diagnosed with primary gastrointestinal stromal tumor of the small bowel mesentery. He had an uneventful postoperative course and was discharged on the second postoperative day in a good condition. The case analysis showed that the diagnosis of gastrointestinal stromal tumor is likely with the emergence of CD117, despite of its occurrence at rare sites and it is a vague clinical picture.
