摘要: [摘要]〓
〖HTH〗目的〖HTSS〗〖KG*2〗探讨朗格汉斯细胞组织细胞增生症(Langerhans cell histiocytosis,LCH)临床病理特点、免疫表型、诊断、鉴别诊断及预后。
〖HTH〗方法〖HTSS〗〖KG*2〗分析15例儿童LCH临床资料及组织病理学特点,采用免疫组织化学法检测15例LCH和15例其他非LCH的组织细胞疾病(nonLangerhans cell histiocytic disorder,NLCHD)Langerin、CD1a、S100、CD68的表达情况,并分析其临床病理意义。
〖HTH〗结果〖HTSS〗〖KG*2〗15例LCH的组织学特点:受累器官内朗格汉斯细胞弥漫增生,细胞圆形、卵圆形,核肾形、不规则形,见核沟及核皱褶。免疫组织化学特点:LCH和NLCHD中Langerin表达率分别为100%和0%(P<005),CD1a表达率分别为93.3%和13.4%(P<005),S100表达率分别为100%和86.7%(P>0.05),CD68表达率分别为26.7%和20.0%(P>005)。
〖HTH〗结论〖HTSS〗〖KG*2〗LCH病理诊断中,Langerin和CD1a高度敏感且特异性强,可作为首选免疫组织化学指标。

Abstract:

[Abstract] Objective〖HTSS〗〓To investigate the clinicopathological features, immunophenotype, diagnosis, differential diagnosis and prognosis of Langerhans cell histiocytosis(LCH) in Langerhans.
〖HTH〗〖WTHZ〗Methods〖HTSS〗〓Clinical data and histopathological features of 15 children with LCH were analyzed. The expression of Langerin, CD1a, S100 and CD68 in 15 cases of LCH and 15 cases of nonLangerhans cell histiocytic disorder(NLCHD) were detected by immunohistochemical method, and the clinical pathological significance was analyzed.
〖HTH〗〖WTHZ〗Results〖HTSS〗〓Histological features of 15 cases of LCH: Langerhans cell of the affected organs proliferated and proliferated. The cells were round, oval, nuclear, and irregular. Immunohistochemical characteristics: the expression rates of Langerin in LCH and NLCHD were 100% and 0% respectively(P<005), and the CD1a expression rates were 93.3% and 13.4% respectively(P<005). The expression rates of S100 were 100% and 86.7% respectively(P>005), and the CD68 expression rates were 26.7% and 20.0%, respectively(P>005).
〖HTH〗〖WTHZ〗Conclusion〖HTSS〗〓In the pathological diagnosis of LCH, Langerin and CD1a are highly sensitive and specific, and can be used as the first immunohistochemical index.
