UNLABELLED Oral lichen planus and lichenoid reactions are autoimmune type inflammatory conditions of the oral mucosa with similar clinical and histological characteristics. Recent data suggest that oral lichenoid reactions (OLR) present a greater percentage of malignant transformation than oral lichen planus (OLP). OBJECTIVE To compare the expression of bcl-2 and COX-2 in OLP and OLR. METHO...

Oral lichen planus (OLP) is a chronic inflammatory disease of the oral mucosa which is considered by the World Health Organization (WHO) as a premalignant condition. One step in malignant development is so called epithelial mesenchymal transition (EMT), a process whereby epithelial cells acquire mesenchymal characteristics. A factor known to induce EMT is the transforming growth factor-β (TGF-β...

BACKGROUND Oxidative stress is involved in oral lichen planus (OLP) pathogenesis; meanwhile anthocyanins are natural antioxidants present in grapes skin. OBJECTIVES The aim of this research was to verify the utility of anthocyanins, extracted from grapes skin, for the local treatment of oral lichen planus and to compare it with clobetasol propionate- neomycin -nystatin cream (CP-NN). STUDY ...

Oral lichenoid reactions are considered variants of oral lichen planus and may be regarded as a disease by itself or as an exacerbation of an existing oral lichen planus by the presence of medication or dental materials. They represent a type IV hypersensitivity reaction and most commonly affect the oral mucosa in direct contact with an amalgam restoration. Oral lichenoid reactions can cause si...

Lichen planus is an inflammatory dermatosis with a prevalence of approximately 1%. Recent meta-analyses show that patients with hepatitis C virus have a 2.5- to 4.5-fold increased risk of developing lichen planus. Lichen planus has also followed vaccinations and has specifically been attributed to the hepatitis B vaccine, the influenza vaccine, and the tetanus-diphtheria-acellular pertussis vac...

Unstimulated whole salivary p53 was evaluated in non-involved subjects, in patients suffering from oral lichen planus (OLP) and squamous cell carcinoma (SCC). A total of 34 patients with OLP, 24 patients suffering from oral SCC and 41 non-involved participants were enrolled. The unstimulated whole saliva p53 level was assayed by ELISA.

The significance of tumor-infiltrating lymphocytes (TIL) has attracted much attention in relation to the prognosis of patients. We herein examined the activation status of the TILs in relation to the tumor microenvironment. By using frozen sections of human early-stage tongue cancers (n = 22), the TILs in the cancer nests and those in the cancer stroma were compared for the expression of PD-1, ...
