In a recently held WHO workshop it has been recommended to abandon the distinction between potentially malignant lesions and potentially malignant conditions and to use the term potentially malignant disorders instead. Of these disorders, leukoplakia and erythroplakia are the most common ones. These diagnoses are still defined by exclusion of other known white or red lesions. In spite of tremen...

Lichen Planus (LP) is a chronic mucocutaneous disease with several variants defined by the configuration of lesions, the morphological appearance, and the site of involvement. Although exact cause of LP is not known, it is thought that it is most likely an immunologically mediated reaction especially a cell-mediated immune response of unknown origin. Typical lesion is seen as a pruritic, papula...

STATEMENT OF PROBLEM Lichen planus is a chronic inflammatory immunologic-based disease involving skin and mucosa. This disease is generally divided into two categories: erosive and non-erosive. Many etiologic factors are deliberated regarding the disease; however, the disorders of immune system and the role of cytotoxic T-lymphocytes and monocytes are more highlighted. Zinc is an imperative ele...

lichen planus (lp) is a chronic mucocutaneous disease widely recognized in adults, but uncommon in children. the purpose of this paper is to report two cases of lp in children. the diagnosis was made based on clinical and histopathological findings. the treatment consisted of antifungal and multivitamin therapy. regression of lesions was observed. the patients are still under follow up. althoug...

Lichen planus (LP) is a common disorder in which auto-cytotoxic T lymphocytes trigger apoptosis of epithelial cells leading to chronic inflammation. Oral Lichen Planus (OLP) can be a source of severe morbidity and has a small potential to be malignant. The diagnosis of OLP can be made from the clinical features if they are sufficiently characterized, but biopsy is recommended to confirm the dia...

UNLABELLED Oral lichen planus is one of the most common dermatological diseases presenting in the oral cavity; the prevalence in the general population is 1% to 2%. Although relatively frequent, oral lichen planus is the target of much controversy, especially in relation to its potential for malignancy. AIM This study aimed to make clinical and histopathological considerations regarding oral ...

HLP: hypertrophic lichen planus LP: lichen planus PEH: pseudoepitheliomatous hyperplasia SCC: squamous cell carcinoma INTRODUCTION Hypertrophic lichen planus (HLP) and squamous cell carcinoma (SCC) share many clinical and histopathologic characteristics, making them difficult to distinguish. HLP may undergo malignant transformation, leading to the development of SCC within HLP. We present a cas...

Background: Oral Lichen Planus (OLP) is a chronic autoimmune disease that could be considered as a potential premalignant status. Objective: To evaluate the miRNA-146a and miRNA-155 expression levels in patients with oral Lichen planus lesions compared to healthy subjects with normal oral mucosa. Methods: Forty patients with oral lichen planus and 18 healthy age and gender-matched controls were...

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...
