13. The presence of Helicobacter pylori in oral cavities of patients with leukoplakia and oral lichen planus
ABSTRACT Objective Helicobacter pylori infection is one of the most common bacterial infections in men. This gastrointestinal pathogen is closely related to gastritis, peptic ulcers, and the increased risk of gastric cancer. Numerous studies have indicated oral cavities as possible Helicobacter pylori reservoirs. Helicobacter pylori has been detected both i

14. In situ carcinoma developed over oral lichen planus: a case report with analysis of BUB3, p16, p53, Ki67 and SOX4 expression
AbstractOral lichen planus (OLP) represents a common mucocutaneous disease. Various authors have suggested that OLP has malignant potential; however, the mechanisms involved in malignant transformation have not yet been elucidated. A 79-year-old man presented a white lesion for five months in the buccal mucosa diagnosed as OLP. After two months using 0.05% c

15. Esophageal lichen planus
Abstract Lichen planus is a chronic inflammatory disease that affects the skin, mucous membranes, nails and scalp. Esophageal lichen planus is a rarely reported manifestation of lichen planus, presenting itself commonly in middle-aged women, with symptoms such as dysphagia. We report a case of esophageal lichen planus in a 54-year-old woman associated with o

16. Oral lichen planus: study of 21 cases
Abstract BACKGROUND: Lichen planus is considered to be the most common dermatological disease involving the oral mucosa. OBJECTIVE: To investigate the profile, clinical features, and the presence of dysplasia and candidiasis in patients with oral lichen planus. METHODS: A total of 21 patients were selected from 258 patients at risk for oral cancer developmen

17. TNF-α, TNF-β and IL-10 gene polymorphism and association with oral lichen planus risk in Saudi patients
Objectives Oral lichen planus (OLP) is a chronic inflammatory oral mucosal disease. Cytokines play an important role in the pathogenesis and disease progression of OLP. Various reports have implicated cytokine gene polymorphisms in susceptibility to develop some immune mediated conditions including OLP. The purpose of this study was to investigate the assoc

18. Differential expression of stem cell-like proteins in normal, hyperplastic and dysplastic oral epithelium
Objective The identification of stem cells (SC) remains challenging. In the human oral mucosal epithelium, these cells are believed to be in the basal layer (stem cell niche), but their exact location is unclear. The aim of this study was to examine the dysplastic oral epithelium for these SC-like proteins in order to assess their diagnostic value as biomar

19. Oral potentially malignant disorders in a large dental population
Objectives Oral cancer (OC) may be preceded by clinically evident oral potentially malignant disorders (OPMDs). Oral carcinogenesis is a multistep process that begins as epithelial hyperplasia and progresses to oral epithelial dysplasia and finally to fully malignant phenotypes. The aim of our study was to estimate the prevalence of OPMDs in a large popula

20. Evaluation of Cellular Proliferative Activity in Patients with Oral Lichen Planus and Hepatitis C through AgNOR Method
O propósito deste estudo foi avaliar o potencial proliferativo celular das lesões de líquen plano bucal (LPB) de pacientes sem vírus da hepatite C (VHC) por meio do método AgNOR, comparando-o ao potencial proliferativo celular da mucosa bucal normal de portadores de VHC, tratados ou não com interferon e ribavirina. Um estudo transversal foi realizado p

21. Syndrome in Question
Multiple autoimmune syndrome is a rare condition, described by Humbert and Dupond in 1988. It is defined by the association of at least 3 autoimmune diseases in the same patient. Vitiligo is the most common skin condition in this syndrome. This article presents the case of a 31-year-old male with vitiligo, alopecia areata, Crohn's disease, psoriasis vulgaris

22. Caracterização clínica-histológica e estudo de polimorfismos das respostas T-Helper-1 e 2 (Th1/2) nas doenças imunologicamente mediadas com manifestações bucais : líquen plano oral e reação liquenóide oral por amálgama dental / Clinical-histological characterization and study of polymorphisms of T-Helper-1 and 2 (Th1 / 2) responses in immune-mediated diseases with oral manifestations : oral lichen planus and amalgam-associate oral lichenoid reaction
As lesões liquenóides orais (LLO), como líquen plano oral (LPO) e reação liquenóide oral por amálgama dental (RLO-AD), são doenças imunologicamente mediadas (DIM) com características histopatológicas semelhantes, porém com prognósticos distintos. As suas etiopatogenias têm sido relacionadas a polimorfismos gênicos e secreção citocinas de inf

23. A comparative study of apoptosis in reticular and erosive oral lichen planus
O líquen plano oral (LPO) é uma doença crônica inflamatória, provavelmente auto-imune, com diferentes formas clínicas. Os tipos mais comuns são o reticular e o erosivo. A apoptose participa da destruição dos ceratinócitos basais, no entanto o seu papel na perpetuação do infiltrado linfocitário subepitelial ainda não foi investigado. Para avalia

24. Expressão imuno-histoquímica de Bcl-2, Ki-67 e caspase-3 ativa em líquen plano oral e leucoplasia com diferentes graus de displasia / Immunohistochemical expression of Bcl-2, Ki-67 and active caspase-3 in oral lichen planus and leukoplakia with different degrees of dysplasia
O líquen plano oral (LPO) é uma doença inflamatória crônica de causa desconhecida, e seu potencial de malignização é um tema bastante controverso. Diversos estudos têm sugerido que pacientes portadores de líquen plano apresentam um maior risco de desenvolver câncer. Contudo, muitos autores acreditam que não haja dados suficientes que provem uma a
