小肠恶性间质瘤属于胃肠道间质瘤(gastrointestinal strom altumors,G ISTs)是一种非常少见的非上皮性肿瘤,临床变异较大,病理形态复杂多样,传统上几乎都归为平滑肌肿瘤。胃肠道间质瘤(G ISTs)是一种免疫表型上表达K IT蛋白(CD117)、遗传学上存在频发性c-k it基因突变、组织学
Small intestinal malignant stromal tumors are gastrointestinal stromal tumors (G ISTs), a rare form of non-epithelial tumor with large clinical variability and complex and diverse pathology. Traditionally, almost all of them are classified as smooth muscle tumors. Gastrointestinal stromal tumors (G ISTs) are an immunophenotypically expressed K IT protein (CD117) genetically linked to frequent c-kit gene mutations, histology
