RESUMO
Introduction: sialolithiasis is the most common form of obstructive sialadenitis caused by a mixture of different calcium phosphates and an organic matrix. It is one of the most common salivary gland diseases, often attributed to the submandibular gland, with no relation to age or gender. However, it is rarely reported in the minor salivary glands. Objective: the present study aims to report auncommon clinical finding case of a sialolithiasisof minor salivary gland in labial mucosa. Case report: a 43-year-old female patient presented with a single, yellow and asymptomatic nodule in the labial mucosa at clinical examination. The clinical hypotheses were lipoma and fibrous hyperplasia. The lesion was biopsied, and the histopathological analysis showed a mineralized tissue. The final diagnosis was sialolithiasis and the patient remained under follow-up (8 months) without relapse. Conclusion: this case shows that sialolithiasis should be included in the diagnostic hypotheses when occur in a minor salivary glands area and emphasizes the importance of a complete clinical examination since it was not complaint of the patient.(AU)
Introdução: a sialolitíase é a forma mais comum de sialadenite obstrutiva causada por um composto de diferentes produtos, como fosfato de cálcio e matriz orgânica. É uma das doenças mais comuns das glândulas salivares, geralmente atribuídas à glândula submandibular, sem relação com idade ou sexo. No entanto, raramente é relatada nas glândulas salivares menores. Objetivo: reportar um achado clínico incomum de sialolitíase em glândula oral menor na mucosa labial. Relato de caso: uma paciente do sexo feminino, de 43 anos, apresentou nódulo único, amarelo e assintomático na mucosa labial durante o exame clínico. As hipóteses clínicas foram lipoma e hiperplasia fibrosa. A lesão foi encaminhada para biópsia e a análise histopatológica mostrou um tecido mineralizado. O diagnóstico final foi de sialolitíase e o paciente permaneceu em acompanhamento por 8 meses sem recidiva. Conclusão: este caso mostra que a sialolitíase deve ser incluída nas hipóteses diagnósticas de lesões em áreas de glândulas salivares menores e enfatiza a importância de um exame clínico completo, pois não se tratava da queixa principal da paciente.(AU)

INTRODUCTION: Oral lichen planus (OLP) is an idiopathic chronic mucocutaneous disease with a wide range of clinical manifestations, including white reticular patches, erosive/ulcerative and atrophic lesions, both associated with intense symptomatology. Topical corticosteroids are commonly used as standard therapy. However, patients frequently present relapses after the discontinuation of treatment as well as developing resistance to corticosteroid therapy. Photobiomodulation (PBM) has been shown to be a potential therapeutic tool to treat inflammatory disorders, including OLP. The aim of this study was to compare the efficacy of PBM (660 nm) with corticosteroid therapy with clobetasol propionate 0.05% for the treatment of OLP. METHODS AND ANALYSIS: Forty-four patients with symptomatic and histopathological diagnosis of OLP will be randomised into two experimental groups in a double-blind manner: control group (n=22): clobetasol propionate 0.05%+placebo PBM, and experimental group (n=22): PBM (λ=660 nm, power 100 mW, radiant exposure: 177 J/cm2 and 0.5J per point)+placebo gel. Laser will be applied 2×/week for 1 month and clobetasol propionate three times a day for 30 days and the same for placebo treatments. The primary variable (pain) and the secondary variables (clinical score, evaluation of functional scores, clinical resolution, OLP recurrence, quality of life and anxiety and depression) will be evaluated at the baseline, once a week during treatment (depending on the variables) and after 30 days and 60 days of follow-up. Pain will be evaluated using visual analogue scale and clinical characteristics will be scored using the Thongprasom Index. The quality of life and anxiety and depression will be evaluated by Oral Health Impact Profile-14 questionnaire and by Hospital Anxiety and Depression Scale for anxiety scale, respectively. The serum and salivary levels of interleukin (IL)-6, IL-10, IL-1ß, INF-γ and tumour necrosis factor-α will be evaluated by ELISA at baseline and at the end of treatment. ETHICS AND DISSEMINATION: This protocol was approved (#2.375.410) by the Nove de Julho University (UNINOVE) Research Ethics Committee. The data gathered using this protocol will be published in a peer-reviewed journal. TRIAL REGISTRATION NUMBER: NCT03320460.

A hiperplasia endotelial papilífera intravascular (HEPI) é uma lesão vascular não neoplásica, benigna e rara, especialmente em cavidade bucal. O presente artigo relata dois casos com diferentes apresentações clínicas de HEPI, envolvendo o lábio inferior. O primeiro caso se refere a um paciente que apresentava nódulo único submucoso, endurecido, arroxeado e assintomático em mucosa labial inferior. E o segundo se reporta a uma paciente que apresentava aumento de volume assintomático em lábio inferior com a mucosa entumecida e arroxeada desde o fundo de sulco. O exame histológico revelou vasos dilatados com proliferação de células endoteliais arredondadas, associadas a estruturas papilares, de tecido conjuntivo projetadas para o lúmen vascular, associadas a um trombo organizado, no primeiro caso, e a um hemangioma, no segundo. A ausência de células inflamatórias, atipia e necrose celular excluíram outras lesões vasculares, sendo o diagnóstico final de HEPI. O prognóstico da HEPI é excelente, uma vez que recidivas são raramente relatadas. A HEPI pode ser incluída no diagnóstico diferencial clínico de lesões labiais únicas, arroxeadas e endurecidas. E por caracterizarse histologicamente por uma proliferação de células endoteliais, é importante estabelecer o diagnóstico diferencial com o angiossarcoma, uma lesão de tratamento mais agressivo e pior prognóstico...

Intravascular papillary endothelial hyperplasia (IPEH) is a nonneoplastic vascular benign and rare lesion, especially in oral cavity. This article reports two cases of IPEH, with different clinical presentation, involving the inferior lip. The first case refers to a patient presenting a single submucosal indurated purplish and asymptomatic nodule in the lower labial mucosa. And the second, to a patient presenting an asymptomatic increase in the lower lip associated with a swelling and purplish oral mucosa. Histological examination showed dilated vessels with rounded endothelial cells proliferation associated with papillary structures of connective tissue projected to vascular lumen, associated with an organized thrombus in first case and a hemangioma in the second. The absence of inflammatory cells, cytologic atypia and necrosis excluded other vascular lesions, being the final diagnosis of IPEH. The prognosis of IPEH is excellent since recurrences are rarely reported. Isolated purplish and indurated labial lesions can include the IPEH as a possible clinical hypothesis. And, since is histologically characterized by a proliferation of endothelial cells, is crucial the establishment of the histological differential diagnosis with angiosarcoma, which requires a more aggressive treatment and has worse prognosis...
