The dendrite cells of Langerhans, first identified in the epidermis, have now been observed in the middle and superficial layers of the normal human oesophageal mucosa. They exhibit typical Langerhans granules, but no desmosomes and tonofilaments. They often have irregular indented nuclei, with a relatively pale cytoplasm contrasting with that of the adjacent squamous cells. These cells are sometimes difficult to distinguish from intra-epithelial lymphocytes, which are also encountered in the oesophageal mucosa and which share certain ultrastructural characteristics with Langerhans cells.
朗格汉斯树突状细胞最初在表皮中被识别，现在已在正常人类食管黏膜的中层和表层被观察到。它们呈现出典型的朗格汉斯颗粒，但没有桥粒和张力丝。它们的细胞核常呈不规则凹陷状，与相邻鳞状细胞相比，细胞质相对较淡。这些细胞有时难以与上皮内淋巴细胞区分开来，上皮内淋巴细胞在食管黏膜中也会出现，并且与朗格汉斯细胞具有某些超微结构特征。
