关于隆突性纤维肉瘤(DermatofibrosarcomaProtuberans,DFP)的组织来源大致可归纳为:纤维母细胞和组织细胞,神经组织以及间叶组织。国外近年来已应用免疫组织化学技术对DFP的组织来源进行了研究,在国内尚未见报道。本研究采用了12种免疫标记物包括5个单克隆抗体对36例肿瘤(包括20例DFP)联合标记,对各种组织来源进行了较全面的探索及各种免疫标记物在DFP鉴别诊断中应用价值。 The tissue sources of Dermatofibrosarcoma Protuberans (DFP) can be roughly summarized as: fibroblasts and histiocytes, neural tissue and mesenchymal tissue. In recent years, foreign organizations have applied immunohistochemical techniques to study the origin of DFP, and have not been reported in China. In this study, 12 immune markers including 5 monoclonal antibodies were used to jointly label 36 tumors (including 20 DFPs). A variety of tissue sources were fully explored and various immune markers were used in differential diagnosis of DFP. Value.
