扁平苔癣是一种比较常见的皮肤病,通常累及口腔粘膜。自从1869年Wilson首次描述该病以来,对于其病因和发病机制的探讨,几乎没没有任何进展。大多数皮肤病和口腔病理学教科书都提到,紧张和焦虑可能是扁平苔癣的发病因素。但事实上,这种关系只是一种猜测而已,很少有人对此作过研究。 Lichen planus is a common skin disease that usually affects the oral mucosa. Since Wilson first described the disease in 1869, there has been almost no progress in the exploration of its etiology and pathogenesis. Most dermatology and oral pathology textbooks have mentioned that stress and anxiety may be the cause of lichen planus. But in fact, this relationship is only a guess, and few people have studied it.
