朗格汉斯细胞组织细胞增生症临床病理学分析

回顾性分析2004年1月至2014年1月收治的13例朗格汉斯细胞组织细胞增生症患者临床病理资料,其中男性8例,女性5例,患者年龄6 ～63岁,平均年龄35岁,多为成年人.13例患者共有15处病变,镜下见组织细胞样瘤细胞弥漫分布,可见核沟,背景内有数量不等嗜酸性粒细胞及其他炎细胞浸润.免疫组化结果显示肿瘤细胞表达S-100、CD1a、朗格汉斯细胞产生的特异性凝集素.治疗后随访6～101个月,均健在.免疫组化标记有助于明确诊断及鉴别诊断.

Clinicopathological analysis of langerhans cell histiocytosis

The clinicopathological data of 13 patients with Langerhans cell histiocytosis （LCH） from January 2004 to January 2014 were retrospectively analyzed.There were 8 males and 5 females with a mean age of 35 （6-63）years.For all 13 cases,there were 15 lesions.Histologically,there was a diffuse distribution of Langerhans cells accompanied by a variable number of eosinophils and some other inflammatory cells.Immunohistochemical study showed tumor cells were positive for S-100 protein,CD1a and Langerin.During a follow-up period of 6-101 months,all survived.The diagnosis of LCH was assisted by immunophenotypic analyses for S-100,CD1a and Langerin.Combination therapy was effective.Most patients had an excellent prognosis.
