Duodenal stromal tumor: report of a case.

Gastrointestinal stromal tumors are rare tumors of the gastrointestinal (GI) tract that arise from primitive mesenchymal cells. Gastrointestinal stromal tumors account for approximately 80% all of gastrointestinal mesenchymal tumors. Duodenal stromal tumors (DSTs) manifest with unexplained melena, pain, bleeding, anemia, sometimes a partial duodenal obstruction and, rarely, with obstructive jaundice. If the tumor is successfully treated, its prognosis is usually good because of its non-aggressive nature. If resected, the prognosis is favorable in a majority of cases, and it is much better than in carcinomas of the duodenum. In this article, we report a case of DST originating from the first and second portion of the duodenum. Our patient did not have any problems postoperatively and remained symptom-free at 18 months after surgery.
