　　本文分析了9例EB病毒（Epstein-Barrvirus，EBV）阳性黏膜皮肤淋巴组织增生性病变的病理特征，这拓展了EBV阳性黏膜皮肤溃疡的概念。9例病例中有女性5例和男性4例，平均年龄74岁（范围，55~87岁），其中2例为HIV阳性患者。病变位于口咽、皮肤、直肠和生殖器黏膜。组织病理学上，6例显示出多形性以及3例表现为单形性和弥漫性，4例表现出血管改变（具有多形性和单形性模式各2例）。其中3例表达PDL1。除了在肿瘤性淋巴细胞中表达外，在1例口咽部病变的相邻黏膜上皮细胞中同样检测到了EBV。9例病例在进行了局部治疗或系统性化疗后，病变均有改善或消退。本文通过对9例病例的分析，
　　扩展了EBV阳性黏膜皮肤溃疡的疾病谱系，包括HIV阳性病例、局限于单一解剖区域的多处病灶、具有血管中心性病变模式以及一些具有单一大细胞形态的病例。本文同时讨论了EBV阳性黏膜皮肤溃疡与经典EBV阳性大B细胞淋巴瘤的不同临床病理诊断特征。 　　The American Journal of Surgical Pathology中文版声明：
