定义
扁平苔藓是一种皮肤和粘膜的炎症性疾病，以表皮/上皮和真皮/真皮层之间的剧烈炎症为特征。其临床表现因其发展程度和发病部位而异。在皮肤上，典型表现为对称性瘙痒爆发、平顶的粉红色或紫色丘疹或斑块。头皮或指甲基质受累可分别导致头发或指甲永久性脱落。虽然粘膜受累可无症状，但它可引起明显的疼痛和痛苦，特别是当它是侵蚀性的。
Lichen planus is an inflammatory disease of skin and mucous membranes characterised by intense inflammation at the interface between epidermis/epithelium and dermis/corium. Its clinical manifestations vary according to how acutely it develops and to where it attacks. On the skin it typically presents as a symmetrical eruption of itchy, flat-topped pink or purple papules or plaques. Involvement of the scalp or nail matrix can produce permanent loss of hair or nails respectively. Although mucous membrane involvement can be asymptomatic, it can cause significant pain and distress, particularly when it is erosive.
