目的 探讨孤立性纤维性肿瘤 (SFT)的临床病理特征及诊断要点 ,免疫组化特点。方法 对 10例SFT的临床表现、病理组织学观察及免疫组化标记进行分析。结果 10例SFT发生部位各异 ,组织学特征为形态多样性 ;免疫组化CD34 、VM及bcl 2呈阳性表达。结论 SFT有细胞分布疏密不均及多态性生长方式的组织学特征。根据光镜及免疫组化特点 ,可与其他软组织肿瘤鉴别。此瘤有必要长期随访
Objective To investigate the clinicopathological characteristics, diagnosis points and immunohistochemical characteristics of solitary fibrous tumor (SFT). Methods The clinical manifestations, histopathological observation and immunohistochemical staining of 10 cases of SFT were analyzed. Results SFT occurred in 10 cases with histological features of morphological diversity; immunohistochemical expression of CD34, VM and bcl 2 were positive. Conclusion SFT has the cell density distribution and the histological characteristics of polymorphic growth pattern. According to light microscopy and immunohistochemical features, with other soft tissue tumors to identify. This tumor is necessary long-term follow-up
