口腔白斑和扁平苔藓(OLP)与正常口腔粘膜的区别:如基板中断、增厚、增殖,基细胞张力丝增多、基细胞和棘细胞间隙变性和增宽;透明角质颗粒异位及炎症细胞侵入上皮等是一致公认的。但对基板改变的严重程度及其与临床关系、炎症细胞及其与上皮细胞间可能的相互反应等却有分歧。为此作者在电镜下观 Differences between oral leukoplakia and OLP and normal oral mucous membranes: disruption, thickening, proliferation of basal cells, increase of basal cell tension filaments, degeneration and widening of basal cells and spine cells; ectopic transmembrane granules and invasion of inflammatory cells Epithelial etc. are generally recognized. However, there is disagreement about the severity of substrate changes and their clinical relevance, and the possible interactions between inflammatory cells and epithelial cells.
