INTRODUCTION. Lichen planus is a chronic inflammatory disease that affects the skin and the mucus membrane. Oral lichen planus (OLP), the mucosal counterpart of cutaneous lichen planus, presents frequently in the fourth decade of life and affects women more than men in a ratio of 1.4:1.[] The disease affects 1-2% of the population.[2,3] It is seen clinically as reticular, papular, plaque. Oral lichen planus (OLP) is a chronic mucocutaneous disorder of stratified squamous epithelium of uncertain etiology that affects oral and genital mucous membranes, skin, nails, and scalp. LP is estimated to affect 0.5% to 2.0% of the general population Oral lichen planus is a disease that is more common in women, usually appearing in the fifth and sixth decades of life. The most common clinical form is reticular, manifesting mainly in the buccal mucosa. Histological findings characteristic of oral lichen planus include hydropic degeneration of the

The prevalence of lichen sclerosus affecting only the oral mucosa is extremely rare and only 26 cases with histologically verified oral lichen sclerosus have been reported. Main observations A 60-year-old man was referred to our hospital for complaints of white lesions in the oral cavity, which was otherwise asymptomatic and did not have any. Lichen planus pigmentosus describes ill-defined oval, greyish brown marks on the face and neck or trunk and limbs without an inflammatory phase. It is a form of acquired dermal macular hyperpigmentation. It can be provoked by sun exposure, but it can also arise in sun-protected sites such as the armpits Oral Lichen Planus. Lichen planus is a disease that can affect the skin and any lining mucosa. This could be the oral, esophageal, vaginal mucosa as well as the skin. Often, it is found only in the oral cavity. Overall, lichen planus affects approximately 2 percent of the population. Although the disorder may occur in all age groups, women over.

Oral cancer (also known as mouth cancer or oral cavity cancer) is most often found in the tongue, the lips and the floor of the mouth. It also can begin in the gums, the minor salivary glands, the lining of the lips and cheeks, the roof of the mouth or the area behind the wisdom teeth. The majority of oral cancers arise in the squamous cells. 1 Definitive diagnosis of lichen planus is made on the basis of distinctive clinical features in conjunction with characteristic microscopic tissue appearance obtained through biopsy. A dermatologist or specialist in oral pathology typically makes the primary diagnosis of oral lichen planus Background: Oral potentially malignant disorders, which include oral lichen planus (OLP), are clinical presentations that carry a risk of development to cancer in the oral cavity. Oral lichenoid lesions (OLLs) are also termed interface/lichenoid mucositis. Malignant transformation of them remains controversial, but distinct clinical and histological criteria for how to differentiate OLP from.

Final diagnosis of oral lichen planus and oral lichenoid lesions: The clinical and histopathological criteria must be included in order to establish a final diagnosis. Both the clinical and histopathological criteria must be met in order to diagnose oral lichen planus. The term oral lichenoid lesions is to be used under the following conditions Examination revealed typical lichen planus confined to the oral cavity. Numerous confluent reticular lesions covered nearly all of the mucous membranes of the cheeks. On the left side of the tongue, two oval annular lesions were present, unnoticed by the patient. The lips were not involved. No other lesions were found Definition Lichen planus is a condition that forms a very itchy rash on the skin or in the mouth. Lichen Planus is a common skin disease that often affects only the oral cavity or both the skin and oral cavity. The white lesions it produces resemble the lichen that grows on trees and that is the origin of the name. This reaction may be caused by genetic factors and can be triggered by. Common superficial oral lesions include candidiasis, recurrent herpes labialis, recurrent aphthous stomatitis, erythema migrans, hairy tongue, and lichen planus. Recognition and diagnosis require.

However, the potentially malignant nature of OLP remains unclear. We designed this study to examine the demographic and clinical characteristics of patients with OLP and evaluate the associated malignant transformation rate Lichen planus in the oral cavity is usually asymptomatic and requires no treatment, except for the erosive form, which causes pain and burning and warrants prednisone therapy (20 mg/d).

Studies of the malignant potential of oral lichen planus (OLP) have been hampered by inconsistencies in the diagnostic criteria used for OLP, the criteria adopted to identify a true case of malignant transformation in OLP, the risk factors for malignant.

Oral lichen planus (OLP) is a common chronic inflammatory disease affecting the oral mucosa. The pathogenesis of OLP is incompletely understood but is thought to be related to the immune system. As the oral cavity is a major reservoir and transmission gateway for bacteria, viruses, and fungi, the microbial composition of the oral cavity could play a role in the pathogenesis of OLP Abstract Lichen planus is often confused with premalignant white lesions of the oral cavity which share certain clinical and histologic characteristics. Two cases of oral squamous-cell carcinoma are presented in which the diagnosis of coexisting lichen planus proved to be erroneous This post contains 33 sorted diagrams of histopathological pictures of pathologies related to oral and maxillofacial regions.
