Oral lichen planus (OLP) is a chronic oral inflammatory disease of unknown etiology. According to reports, 1-2% of OLP patients develop oral squamous cell carcinoma (OSCC) in the long run. While World Health Organization (WHO) classifies OLP as “a potentially malignant disorder,” it is still a matter of debate which mechanisms drive OLP to such a condition. The current hypothesis connecting OLP and OSCC is that chronic inflammation results in crucial DNA damage which over time results in cancer development. Initial studies investigating the OLP and OSCC link were mainly retrospective clinical studies. Over the past years, several amount of information has accumulated, mainly from molecular studies on the OLP malignant potential. This article is a critical review of whether OLP has a malignant potential and, therefore, represents a model of preneoplastic inflammation.

Introduction. Oral lichen planus (OLP) is an autoim- mune disease of unknown etiology, manifested in vari- ous clinical forms. A correlation between intensity of OLP local manifestations and severity of general disturbances predisposing to altered oral mucosa have been poorly investigated. The aim of our study was to identify criteria for assessing OLP severity score. Methods. OLP patients and control subjects (not OLP) matched by hepatobiliary disease and type IIa dyslipidemia were examined. Samples collected during the study were as- sessed by way clinical examination, gas chromatographic analysis of serum free fatty acids (FFA), oral fluid, serum and fecal microbial marker analysis by gas chromatogra- phy/mass spectrometry, laser Doppler flowmetry of the oral mucosa, immunohistochemistry staining with an- ti-CD68 monoclonal antibody specific to apolipoprotein B-100-bearing macrophages. Results. It was found that OLP patients significantly differed from control subjects in the three FFA levels (lauric acid, eicosopentaenoic/ lauric and eicosopentaenoic/linoleic ratios), displayed four pathologic factors matching the altered level of mi- crobial markers. In addition, OLP patients were found to differ in oral mucosa blood filling both inside and outside lesions paralleled with oxidative changes immediately in oral mucosa highlighted as elevated amount of apo- lipoprotein B-100-bearing CD68-positive macrophages. Conclusion. OLP severity score is an integrate parameter which reflects oxidative changes and alterations in oral mucosa microhemocirculation primarily in serum free fat- ty acid composition, altered oral and gut microbiota as well as intensity score of clinical picture.

ABSTRACT Aim Many studies have suggested that a lesion originally diagnosed as oral lichen planus (OLP) has different possibilities of undergoing malignant transformation in time, although these findings remain a controversial issue; for example, some studies reported different values of potential malignancy of OLP. Introduction World Health Organization (WHO) classifies OLP as a “potentially malignant disorder” with unspecified malignant transformation risk, and suggests that OLP patients should be closely monitored. Numerous studies have attempted to confirm the malignant transformation potential of OLP. Review results The Cochrane Controlled Trials Register, Medline and EMBASE databases, PubMed, Google Scholar, Ovid, Up To Date, BMJ Clinical Evidence, MD Consult, and Science Direct were searched for papers published between 1997 and 2015. The medical subject heading search terms were “lichen planus,” “oral lichen planus,” “erosive oral lichen planus,” “dysplasia,” “oral precancerous condition,” “oral premalignant condition,” oral cancer, oral squamous cell carcinoma (OSCC), and atrophic lichen planus. A total of 120 English language abstracts were reviewed, and 50 relevant articles identified. Because of the extensive literature on the association between OLP and SCC, we have divided the data into genetic and nongenetic factors for more accurate assessment. Conclusion In this evidence base, malignant transformation ranges from 0 to 37% with a mean of 4.59%. The highest rate of malignancy was noted in erythematosus and erosive lesions. In this way, follow-up of OLP patients could be carried out more efficiently and appropriately. Clinical significance Oral lichen planus is a premalignant lesion. All types of OLP in any site of oral mucosa must be monitored regularly. How to cite this article Agha-Hosseini F, Sheykhbahaei N, SadrZadeh-Afshar M-S.

Objective. Oral exfoliative cytology (OEC) has been implemented in the diagnosis of pathologic lesions for ages. The present study was undertaken to evaluate the cytomorphological features of some of the commonest potentially malignant disorders (leukoplakia, lichen planus, and oral submucous fibrosis) through a simple procedure and illustrate its importance in mass screening.Materials and Method. A total of 160 subjects with 25–50 years of age were included in the study. Among them, 40 were clinically diagnosed with oral leukoplakia, 40 were diagnosed with oral lichen planus, 40 were diagnosed with oral submucous fibrosis, and 40 were in the control group. The prepared smears were subjected to Papanicolaou stain and analyzed microscopically for the evaluation of the cytomorphological features.Results and Discussion. When analyzed microscopically, 36 (90%) out of the 40 oral leukoplakic lesions showed Class II cytological features whereas 4 (10%) revealed Class I features. Among 40 patients with oral lichen planus, 26 (65%) showed Class II features while the remaining 14 (35%) revealed Class I features. In 40 subjects with oral submucous fibrosis, 32 (80%) showed Class II features while the other 8 (20%) showed Class I features. All the 40 control subjects showed Class I features. Thus, OEC can be widely advocated as an addition to clinical conclusion and an adjunct to biopsy.

Background: Lichen Planus is a common mucocutaneous disease with unknown etiology. Immunodeficiency is a known predisposing factor to this disease. Oral Candidiasis which is an opportunistic fungal infection, commonly affects healthy and immune-compromised patients. Candida has different species bearing different treatments. In this study, researchers aimed to detect the frequency and colonization rate of Candida and its association with different factors such as lesion types of oral lichen Planus (OLP).Materials and Methods: Thirty seven untreated oral lichen Planus patients, attending the Clinical Department of Oral Medicine at Shiraz Dental School in 2011, were selected. Swab method and CHROMagar media were used to obtain samples incubated for 48 hours at 30 ºC. Fungal species were detected considering colony color changes.Results: In the culture test, approximately 80% of samples were positive of non-reticular type. About 40% of positive samples were of Candida non-albicans (C.Non-albicans) type. Among C. Non-albicans, 85% were non-reticular type among OLP patients. There was no significant statistical difference in prevalence of Candida albicans (C.albicans) and C. Non-albicans in OLP patients.Conclusion: Based on results, certain biotypes of Candida were not confirmed responsible for OLP patterns.[GMJ.2014;3(4):252-5]

ABSTRACT Introduction Oral squamous cell carcinoma (OSCC) is the most common malignant tumor of the oral cavity. It is preceded by various potentially malignant conditions like oral leukoplakia and oral lichen planus. Survivin is an inhibitor of apoptosis whose levels have been found increased in oral cancer as well as various potentially malignant conditions. Thus survivin can act as a biomarker and help in early detection of potentially malignant conditions which can prevent its transformation into malignancy. Aim To assess and compare the level of total human salivary survivin in oral leukoplakia, oral lichen planus, oral cancer, and control group. Materials and methods A total of 96 subjects were included in the study, which were further grouped into 24 in each group. The saliva was analyzed for survivin level among all the four groups. Survivin concentration (pg/mL) was studied in relation to clinical data. The results were analyzed using Mann—Whitney U test to derive the statistical difference. Results The average of levels of survivin in control group was 0.199 pg/mL, in oral leukoplakia group 0.312 pg/mL, in oral lichen planus group 0.380 pg/mL, and in oral cancer group 0.430 pg/mL. A comparison of all these groups revealed statistically significant difference among the groups. Conclusion Survivin may not be considered as an independent predictor of the malignant transformation for premalignant lesions but it can be an indicator for an increased risk of malignant transformation.

Oral lichen planus (OLP) is a chronic inflammatory disease of unknown etiology with significant impact on patients’ quality of life. Malignant transformation into oral squamous cell carcinoma (OSCC) is considered as one of the most serious complications of the disease; nevertheless, controversy still persists. Various factors seem to be involved in the progression of malignant transformation; however, the mechanism of this process is not fully understood yet. Molecular alterations detected in OLP samples might represent useful biomarkers for predicting and monitoring the malignant progression. In this review, we discuss various studies which highlight different molecules as ominous predictors of OLP malignant transformation.
