6例胃肠道间质瘤临床病理观察

Clinical pathology observation of gastrointestinal stromal tumor in 6 casesf

目的探讨胃肠道间质瘤的临床病理特点。方法分析经手术病理证实胃肠道间质瘤6例的病理特征及随访情况。结果 6例肿物均位于胃肠道黏膜下和(或)肌间。4例为梭形细胞型,高度恶性。2例上皮细胞型,交界性。结论①发生于胃肠道间叶性肿瘤经免疫组化证实多为胃肠道间质瘤。②日常工作中如何掌握间质瘤的诊断标准,没有免疫组化和其他手段仅靠HE能否做出明确诊断。

ObjectiveTo investigate the clinical pathological characteristics of gastrointestinal stromal tumor.MethodsAnalysis confirmed by surgery pathology pathological features of 6 cases of gastrointestinal stromal tumor and follow-up.Results 6 cases of neoplasm were located between gastrointestinal submucosal and/or muscle. 4 cases of spindle cell type, highly malignant. 2 cases of epithelial cell type, borderline,.Conclusion① Occurred in gastrointestinal mesenchymal tumors confirmed by immunohistochemical for gastrointestinal stromal tumor. ② How to grasp the interstitial tumor diagnosis in routine work standards, not only by immunohistochemical and other means HE can make a definite diagnosis;
