苔藓样黏膜炎

定义

口腔苔藓样粘膜炎是一个描述口腔粘膜临床病理特征的术语，它代表了对药物或接触性过敏原等外在因素或像扁平苔藓那样对假定的自我抗原改变的共同反应终点。临床表现可从无症状白色网状条纹到疼痛性红斑和糜烂。特发性扁平苔藓不能总是与外部制剂引起的苔藓样反应区分开来，在这种情况下，在做出更明确诊断之前，将观察到的变化标为口腔苔藓样粘膜炎是合适的。

Oral lichenoid mucositis is a term describing clinicopathological features of the oral mucosa which represent a common end point in response to extrinsic agents such as drugs or contact allergens, or to presumed altered self-antigens as in lichen planus. Clinical presentation can vary from asymptomatic white reticular striae to painful erythema and erosions. Idiopathic lichen planus cannot always be distinguished from lichenoid reactions to external agents and in such circumstances it is appropriate to label the changes observed as oral lichenoid mucositis until a more definitive diagnosis can be made.
