幼年黄色肉芽肿 (ＪＸＧ)的细胞来源被认为是真皮树突状细胞 ,因为有ⅩⅢａ因子表达 ,但不能解释皮肤外如深部软组织、骨髓、腹膜间、内脏、中枢神经系统等损害的发生。该研究目的是了解ＪＸＧ、皮肤纤维瘤、正常皮肤的单核 /树突状细胞标记物的反应模式 ,并观察树突状细胞特别 The origins of juvenile yellow granulomas (JXG) are considered as dermal dendritic cells because of the expression of factor XIIIa, but they can not explain the occurrence of lesions such as deep soft tissue, bone marrow, peritoneum, internal organs and central nervous system outside the skin. The purpose of this study was to understand the response patterns of mononuclear / dendritic cell markers of JXG, dermatofibroma, and normal skin and to observe the dendritic cell-specific
