简介：我很荣幸应邀为国际眼科理事会前任主席Prof．G．0．H．Naumann主编《AppliedPathologyforOphthal。micMicrosurgeons》（眼显微外科医生应用病理学）写书评。这部专著是Prof．G．0．H．Naumann等多位国际顸尖专家的最新杰作。Prof．G．0．H．Naumann在眼科病理学和显微外科方面造诣颇深、创见良多并卓有建树。

简介：目的：分析眼部黑色素瘤临床和病理学特点,以利于早期正确诊断和治疗。方法：回顾性系列病例研究。收集我院2001-08/2011-08门诊及住院眼部黑色素瘤24例,复习患者的临床和病理资料,所有病例采用常规石蜡切片、HE染色,部分病例常规诊断困难的加做S-100蛋白和HMB-45免疫组织化学染色。Excel建立数据库,应用SPSS17.0软件进行统计学分析。结果：患者24例均为单眼发病,男13例,女11例;左眼14例,右眼10例;3例眼睑恶性黑色素瘤,6例原发性结膜黑色素瘤;15例葡萄膜黑色素瘤。结论：黑色素瘤组织病理学变化多样,多数病例常规病理确诊,免疫组织化学对黑色素瘤诊断和鉴别诊断有重要价值。
