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。
Objective To investigate the clinicopathological features of gastrointestinal stromal tumors. Methods The pathological features and follow-up of 6 cases of gastrointestinal stromal tumors confirmed by surgery and pathology were analyzed. Results All the 6 tumors were located in the gastrointestinal mucosa and / or between the muscles. 4 cases of spindle cell type, highly malignant. 2 cases of epithelial cell type, borderline. Conclusions ① Gastrointestinal mesenchymal tumor is mostly confirmed by immunohistochemistry in gastrointestinal mesenchymal tumors. ② daily work how to master the diagnostic criteria of stromal tumors, no immunohistochemistry and other means can make a clear diagnosis by HE alone.
