结核相关结节性红斑的研究进展

结节性红斑(erythema nodosum,EN)是一种常见的间隔性脂膜炎,以红斑、炎症性皮下结节为主要表现。其病因复杂,目前认为部分EN与结核菌感染关系密切。结核相关EN好发于女性及青少年,最常见的结核病类型是原发型结核和淋巴结结核,但大多数患者缺乏相应结核病表现。其发病机制认为与免疫复合物介导的以及细胞介导的免疫机制有关。EN主要根据皮损病理诊断确诊,其组织学表现为不伴血管炎的间隔性脂膜炎,多有间隔增厚,伴各种炎性细胞浸润。当怀疑结核菌感染时,则需完善结核菌素试验、结核抗体、胸片、痰培养等相关检查以明确诊断。认为即使缺乏明确的结核感染证据,对于结核菌素皮肤试验强阳性的患者,尤其是在结核流行病区,应该进行抗痨治疗。
