Reações liquenoides orais representam um desfecho comum em resposta a agentes extrínsecos (drogas, alérgenos), autoantígenos alterados ou superantígenos. A apresentação clínica pode variar de estrias reticulares brancas assintomáticas a eritema doloroso e erosões. Envolvimento cutâneo e mucoso de outras localizações é comum. Embora o líquen plano oral seja idiopático por definição, as reações liquenoides orais podem ser causadas por medicamentos ou agentes exógenos, como cinamatos e outros aromatizantes. | |||
