Lichen planus and lichenoid reactions of oral mucosa – http://id.who.int/icd/entity/561406981
Oral lichenoid reactions represent a common end point in response to extrinsic agents (drugs, allergens), altered self-antigens, or superantigens. Clinical presentation can vary from asymptomatic white reticular striae to painful erythema and erosions. Cutaneous and mucosal involvement of other sites is common. Although oral lichen planus is by definition idiopathic, oral lichenoid reactions may be caused by medications or exogenous agents such as cinnamates and other flavourings.
