本文对6例中耳胆脂瘤标本进行了透射电镜观察,结果表明:胆脂瘤的复层鳞状上皮无论是细胞层次和形态结构,还是在细胞间的连接方式上均酷似皮肤表皮;胆脂瘤基质的上皮近乎“由外耳道上皮迁入”;LC_3在其基质中积聚可能与胆脂瘤的发生、慢性炎症的存在以及骨质的破坏和吸收有关。
In this paper, 6 cases of middle ear cholesteatoma specimens were observed by transmission electron microscopy, the results showed that: cholesteatoma stratified squamous cell both in the cell hierarchy and morphological structure, or in the intercellular connection of the way resembles the skin epidermis; The epithelium of the lipoma stroma almost “migrated into the external auditory meatus”; the accumulation of LC-3 in its stroma may be related to the occurrence of cholesteatoma, the presence of chronic inflammation and the destruction and absorption of bone.
