Enzyme histochemical, immunohistochemical and ultramicroscopic analysis of 20 human aural cholesteatoma matrices revealed the presence of Langerhans cells, T lymphocytes, B lymphocytes and HLA-DR positive cells. There was no significant difference of the numerical density on the area of Langerhans cells between the cholesteatoma matrices and the normal ear canal skin. The numerical density on the area of T4 and the ratio of T4/T8 of cholesteatoma were higher than those of the normal ear canal skin. Through cell-to-cell interaction, Langerhans cells probably play a key role in skin-related disorders, including cholesteatoma.
对20例人耳胆脂瘤基质进行酶组织化学、免疫组织化学和超微分析，发现存在朗格汉斯细胞、T淋巴细胞、B淋巴细胞和HLA - DR阳性细胞。胆脂瘤基质与正常耳道皮肤之间朗格汉斯细胞区域的数量密度无显著差异。胆脂瘤T4区域的数量密度和T4/T8比值高于正常耳道皮肤。通过细胞间相互作用，朗格汉斯细胞可能在包括胆脂瘤在内的皮肤相关疾病中起关键作用。
