We use immunohistochemical procedures (OKT6) to detect LCs. We have studied tissue samples from surgical operations in cases of chronic otitis media. The samples were from skin of external ear canal, both the superior wall (close to cholesteatoma) and the inferior wall; we took also samples from the cholesteatoma matrix (epidermal and subepidermal stratum). We found LCs in the skin of external ear canal in similar proportion if the samples were of superior or inferior wall. In cholesteatoma tissue (17 cases) we observed LCs in the epidermal stratum in greater proportion than in skin. Sometimes the LCs form aggregates or "clusters".
我们采用免疫组织化学方法（OKT6）来检测朗格汉斯细胞（LCs）。我们研究了慢性中耳炎手术病例的组织样本。这些样本取自外耳道皮肤，包括上壁（靠近胆脂瘤处）和下壁；我们还从胆脂瘤基质（表皮和表皮下层）取材。我们发现，无论样本取自上壁还是下壁，外耳道皮肤中朗格汉斯细胞的比例相似。在胆脂瘤组织（17例）中，我们观察到表皮层中的朗格汉斯细胞比例高于皮肤。有时朗格汉斯细胞会形成聚集物或“簇”。
