Chemical injury consists in damage caused by a substance when it comes into contact with living tissue. Certain drugs can cause this type of lesion in the oral mucosa. Imiquimod (INN) is an example. Erythema, edema, vesicles, erosions, ulcerations and inflammatory reactions are among the adverse effects associated with the use of INN. Nevertheless, since its effects disappear when terminating treatment, INN is still considered an essential drug in the treatment of condyloma acuminata, actinic cheilitis, superficial basal cell carcinoma and molluscum contagiosum. The objective of this work is to report a clinical case of a 34-year-old male patient presenting a symptomatic lesion on the lower and upper lip mucosa; while including a literature review on potential adverse effects when prescribing topical INN 5% for the oral mucosa.

Background: Molluscum contagiosum virus (MCV) is a large double-stranded DNA virus that is a member of the family Poxviridae, and which has a worldwide distribution. As with other poxviruses, MCV does not appear to develop latency but evades the immune system through the production of viral specific proteins. Objective: To evaluate the therapeutic efficacy of imiquimod 5% cream for MCV. Methods: Thirteen children >5 and <10 years old, 19 immune-competent adults and four adults with advanced, but stable HIV-1 disease with >10 MCV lesions were treated with topical 5% imiquimod cream three times weekly for up to 16 weeks. Results: Fourteen of 19 immune-competent adults, four of four adults with HIV-1 disease, and six of 13 children had resolution of their MCV lesions in <16 weeks of imiquimod therapy. Children tended to have more pruritus and inflammatory reactions with imiquimod, although most treated lesions appeared to respond. The development of new MCV lesions resulted in a lower overall resolution of the lesions in children. Imiquimod appeared to be the most efficacious in patients with HIV-1 disease and in the genital area in immune-competent adults. Conclusion: Although topical imiquimod appears to have some efficacy in the therapy of MCV, in children the pruritus correlated relatively well with the development of new lesions. In adults, areas that would be expected to have better penetration appeared to respond more consistently. Although the HIV-1-positive patients had the largest clinical lesions at the onset of therapy, as a group they had the best overall response to therapy.

Although cisplatin is a potent anticancer drug, it instigates oxidative and pro-inflammatory reactions that pose significant and distressing clinical symptoms. Therefore, this study investigated the effects of vitamin C and (or) l-carnitine on cisplatin-induced gastric mucosa damage in rat. The rats were allocated into 6 groups (n = 5). The control group received distilled water, while the treatment groups received cisplatin alone (CIP), or cisplatin with vitamin C, l-carnitine, or their combination. Cisplatin caused disruption of the gastric mucosa histoarchitecture and altered the mucus barrier function. Moreover, the stomach tissue of the CIP-treated group showed increased levels of oxidative stress markers (malondialdehyde and H2O2) and decreased activities of antioxidant (superoxide dismutase, glutathione peroxidase, catalase, glutathione S-transferase) and non-antioxidant (reduced glutathione) enzymes. These deleterious events were accompanied with significant increases in pro-inflammatory cytokines and inflammatory infiltration markers, myeloperoxidase and inducible nitric oxide synthase. However, the administration of both vitamin C and l-carnitine, and not either of the two showed additive effects in attenuating the adverse effects of cisplatin. The histological results agreed with the biochemical assays. The study concluded that the combined administration of vitamin C and l-carnitine, but not the single therapy, could prevent the adverse effects of cisplatin on gastric tissue.

Lichen planus (LP) is a chronic inflammatory disorder that most commonly affects middle-aged individuals. LP involves the skin and/or mucous membranes, including oral, vulvovaginal, esophageal, laryngeal, and conjunctival mucosa. Linear LP, a rare distinct variant of LP, is characterised by pruritic eruption of lichenoid and violaceous papules in a linear distribution. We report an unusual presentation of linear LP in a 14-year-old child that extended from the left anterior nares to upper lip and into the oral mucosa up to the upper gum margin.

Introdução: Quando estamos frente às lesões potencialmente malignas, torna-se imprescindível o acompanhamento rigoroso dessas lesões, pois são lesões frequentes e com risco de transformação maligna consideravelmente relevante, a leucoplasia e a queilite actínica, são as lesões mais comuns encontradas na cavidade bucal. Objetivo: relatar um caso de lesão potencialmente maligna em mucosa labial. Relato de caso: Paciente sexo masculino compareceu à clínica de Diagnóstico VI da Universidade do Oeste de Santa Catarina, com a presença de lesão branca em lábio inferior, o mesmo já se encontrava em acompanhamento há seis anos, com diagnóstico prévio de queilite actínica sem atipia celular (duas biópsias prévias). Aposentado, trabalhava anteriormente como agricultor, ex-fumante e ex-etilista. Clinicamente observava-se lesão esbranquiçada, com aspecto verruciforme, localizada em lábio inferior, medindo 2 cm no maior diâmetro. Além disso, o lábio encontrava-se endurecido, com aspecto roliço. Duas hipóteses de diagnóstico foram levantadas: queilite actínica associada a leucoplasia e carcinoma verrucoso. O paciente foi submetido à nova biópsia incisional. No laudo constatou-se tratar de queilite actínica com displasia epitelial leve e o tratamento proposto foi o uso de protetor labial FPS30, além de acompanhamento clínico semestral. Conclusão: O acompanhamento desse caso clínico foi possível observar alteração no perfil citológico, onde nas primeiras biópsias não era possível observar atipia celular e na biópsia mais recente foi observado uma displasia epitelial leve, portanto o acompanhamento das lesões potencialmente malignas é fundamental para prevenir sua transformação maligna, e uma nova biópsia deve ser realizada sempre que for observada alteração no aspecto clínico da lesão.Descritores: Leucoplasia; Queilite; Biópsia; Lábio.ReferênciasPindborg JJ, Reichart PA, Smith CJ, Van der Waal I.
