胃肠道间质瘤(gastrointestinal stromal tumors,GIST)是来源于胃肠道间叶组织的肿瘤,随着免疫组织化学和电镜技术的发展,大量的研究证明胃肠道间质瘤占胃肠道间叶源性肿瘤的绝大多数,而平滑肌源性肿瘤不常见,神经源性肿瘤更少见。已诊断的平滑肌瘤大多数是间质瘤,笔者搜集在上 Gastrointestinal stromal tumors (GISTs) are tumors derived from gastrointestinal mesenchymal tissue. With the development of immunohistochemistry and electron microscopy, a large number of studies have shown that gastrointestinal stromal tumors (GISTs) occupy the gastrointestinal tract The vast majority of mesenchymal tumors, while the smooth muscle-derived tumors are uncommon, more rare neurogenic tumors. Most of the diagnosed leiomyoma is stromal tumor, the author collected in the last
