胃间质瘤(GISTs)是一种原发于胃的间叶性肿瘤。随着免疫组织化学及分子病理学的发展,近年逐渐被证实为GISTs是一种独立性,非定向分化的间叶性肿瘤,常伴有平滑肌或神经方向分化,特征性表达CD117抗原和CD34抗原,其生物学行为的判断到目前为止还没有可靠的标准。本文收集36例GISTs
Gastric stromal tumors (GISTs) are primary mesenchymal tumors of the stomach. With the development of immunohistochemistry and molecular pathology, in recent years, GISTs have been gradually confirmed as an independent, non-directional differentiation of mesenchymal tumors, often associated with smooth muscle or neural differentiation, the characteristic expression of CD117 antigen and CD34 antigen , The judgment of biological behavior so far there is no reliable standard. This article collected 36 cases of GISTs
