The term gastrointestinal stromal tumor describes a heterogeneous group of tumors of mesenchymal origin with particular histologic features. Their classification has recently been made possible thanks to numerous immunohistochemical and ultrastructural studies. We report the case of a patient who came to our attention because of serious anemia due to a gastrointestinal stromal tumor located between the second and third portion of the duodenum. This pathology, although not frequent, should be considered in the differential diagnosis of gastrointestinal bleeding. In these cases it is important to perform careful endoscopic inspection to the third portion of th duodenum, even when previous tracts evidence lesions that could be responsible for the patient's symptoms.
胃肠道间质瘤这一术语描述了一组具有特定组织学特征的间充质起源的异质性肿瘤。由于众多免疫组织化学和超微结构研究，它们的分类最近才成为可能。我们报告了一例患者，因其十二指肠第二和第三部分之间的胃肠道间质瘤导致严重贫血而引起我们的注意。这种病理情况虽然不常见，但在胃肠道出血的鉴别诊断中应予以考虑。在这些病例中，即使先前的检查部位发现了可能导致患者症状的病变，对十二指肠第三部分进行仔细的内镜检查也很重要。
