扁平苔藓是一种慢性浅在的炎症,皮肤和粘膜病,近十余年来,单发在口腔粘膜上的损害机率愈来愈高,成为口腔粘膜疾病中的常见,多发病之一。自把扁平苔藓看作是一种重要的口腔癌前损害以来,国内外都进行广泛的研究,但至今还是“谜”现仅将我院821例粘膜病历中159例(19.3％)口粘膜扁平苔藓的临床及病理资料进行初步分析讨论。 Lichen planus is a kind of chronic shallow inflammation, skin and mucosal disease. In the recent ten years, the incidence of single oral mucosa damage is higher and higher, becoming one of the common and frequently-occurring diseases in oral mucosal diseases. Since lichen planus is regarded as an important oral precancerous lesion, extensive research has been done both at home and abroad, but so far it remains a mystery. Only 159 cases (19.3%) of 821 mucosal medical records in our hospital are now flat Moss clinical and pathological data for preliminary analysis to discuss.
