The aim of this case report is to present a histologically diagnosed oral lichen planus excised by the CO2 laser. Oral lichen planus is a chronic inflammatory mucocutaneous disease of unknown etiology. Different treatments have been used to manage this condition. A 46 year-old female was referred to the Laser Clinic of the Dental School of the Federal University of Bahia to excise a lesion char...
Neoplastic transformation (development of squamous cell carcinoma / verrucous carcinoma) in lichen planus has been described, especially in the oral form of the disease where an estimated 0.3-3% of patients may develop squamous cell carcinoma. Malignancy though uncommon with cutaneous lichen planus has been described in chronic hypertrophic lesions of lichen planus on the legs, including a case...

Background Lichen planus is classified as a common and chronic papulo – squamous disease. It has been associated with liver disease particularly hepatitis C virus (HCV) infection, in several studies. This study aimed to evaluate the controversial relationship between HCV infection and lichen planus. Patients and methods This was an analytical case-control study. The study included 60 patients w...
oral lichen planus is diagnosed according to clinical and histopathological characteristics.some times all of the classical histopathological features can not be seen.in some articles the presence of mast cells have been noted below the epithelium of oral lichen planus patients.the following study was done to evaluate the number of mast cells in the histopathological sections of 20 oral lichen...
Palmitoylethanolamide (PEA) is a pleiotropic lipid mediator with established anti-inflammatory and anti-hyperalgesic activity. Ultramicronized PEA (PEA-um) has superior oral efficacy compared to naïve (non-micronized) PEA. The aim of the present study was two-fold: (1) to evaluate whether oral PEA-um has greater absorbability compared to naïve PEA, and its ability to reach peripheral and centra...
Lichen planus is a papulosquamous disorder of skin. Genital lichen planus is self limiting disease that resolves without any consequences. Although Lichen planus may coexist with lichen sclerosus et atrophicus, such association in genitalia is not reported so far. We report a case of a forty years old man, presented with a papulosquamous lesion over the prepuce four years back and then he subse...
Lichen planus pigmentosus is a pigmentary disorder of unknown etiology, with diffuse hyperpigmentation of sun-exposed areas, more commonly seen in some ethnic and racial groups. We report an unusual case of lichen planus pigmentosus in a 40-year-old man with Fizpatrick type III skin that was present in a blaschkoid distribution on the trunk, a distribution that has been rarely reported. This un...
BACKGROUND DNA cytometry is a technique that allows densitometric analysis of nuclear DNA of cells and in this way the evaluation of DNA ploidy. OBJECTIVE The purpose of the present study was the evaluation of DNA ploidy in oral leukoplakia and oral lichen planus and correlation with histological dysplasia. METHODS We analyzed oral incisional biopsies from a group of 40 patients with oral l...
Oral lichen planus is a premalignant chronic inflammatory mucosal disorder with unknown etiology. It is a multifactorial disease and in addition to genetic background, infections, stress, drug reactions are suggested as risk factors. Helicobacter pylori which is involved in development of many gastrointestinal lesions may also be implicated in oral lichen planus induction. This is of clear impo...
