1、腱鞘巨细胞瘤47例临床病理研究[摘要]目的探讨腱鞘巨细胞瘤的临床病理特征,对其鉴别诊断进行探讨。方法收集47例腱鞘巨细胞瘤,根据临床病理学特点、形态学观察及免疫组化染色进行分析。结果47例腱鞘巨细胞瘤患者中男15例(31.9%),女32例(68.1%),男女比为1:2.1,平均年龄43岁,231岁者35例(74.5%),发生于手部29例(61.7%)、足部18例(38.3%)。肿瘤细胞由数量不等的中等大小滑膜样多形性单核细胞、破骨样多核巨细胞、泡沫样吞噬细胞组成,伴有不同程度的胶原化,另见散在及灶性炎细胞浸润,部分组织细胞内有
2、含铁血黄素颗粒存在。结论腱鞘巨细胞瘤是一种起源于腱鞘和关节滑膜层的良性病变,为较少见的纤维组织细胞肿瘤,免疫组化检查可作为诊断及鉴别诊断的重要参考依据。[关键词]腱鞘巨细胞瘤;临床病理;鉴别诊断[中图分类号]R738[文献标识码]B[文章编号]1673—9701(2012)25—0073—02Giantcelltumoroftendonsheath:Aclinicopathologicalanalysisof47casesLVGuoqingGANJiyaoZHOUBinDepartmentofPathology,Changji
