Abstract
Lichen planus (LP) is a chronic, inflammatory mucocutaneous disorder associated with systemic diseases such as hepatitis C (HCV). The objective of this study is to evaluate the association between LP and HCV bidirectionally through a systematic review and meta-analysis. A comprehensive search of studies published was performed in the databases of PubMed, Embase, and Web of Science. Out of 18,491 articles, 192 studies were included. The global prevalence of HCV positive (HCV+) in LP patients registered from 143 studies was 9.42% [95% confidence interval (CI), 7.27-11.58%], and from these, 84 studies showed HCV+ 4-fold more frequent in LP than a control group (OR, 4.48; 95% CI, 3.48-5.77). The global prevalence of LP in patients HCV+ recorded from 49 studies was 7.05% (95% CI, 4.85-9.26%), and from these, 15 registered a 3-fold more LP in HCV (OR, 3.65; 95% CI, 2.14-6.24). HCV+ in LP patients showed great geographic variability (OR, 2.7 to 8.57), and the predominantly cutaneous location was higher (OR, 5.95) than the oral location (OR, 3.49). LP in HCV+ patients was more frequent in the Eastern Mediterranean (OR, 5.51; 95% CI, 1.40-15.57). There is a higher prevalence of HCV+ in LP and vice versa than in the control group, especially in certain geographical areas that should be taken into consideration when doing screening in countries with an upper prevalence of HCV among the general population.

Abstract
BACKGROUND To clinicopathologically characterize the diagnosis of oral lichenoid disease (OLD) and its main subtypes: oral lichen planus (OLP) and oral lichenoid lesion (OLL), in order to correctly asses their prognosis. MATERIAL AND METHODS Ambispective cohort study of 384 patients with diagnosis of OLD, based on pre-established clinical and histopathological criteria. We have analysed 272 (70.8%) women and 112 (29.2%), whose mean age was 57.1+/-11.8 years (range 21-90); minimum follow-up time was 36 months. A specific protocol was designed for this study, where we gathered the data of each patient, including malignant transformation. RESULTS OLP was diagnosed in 229 cases (77.9%) and OLL in 85 (22.1%). Tobacco consumption was found in 20.3% of the patients and alcohol intake in 41.1%. Liver pathology was present in 10.7% of the cases, thyroid pathology in 11.5%, arterial hypertension in 15.6%, diabetes mellitus in 7.6%, psycho-emotional disorders in 33.3%, skin involvement in 12% and genital involvement in 4.9%. Ten patients (2.6%) developed an oral squamous cell carcinoma, 5 (1.7%) with OLP and 5 (5.9%) with OLL. CONCLUSIONS OLD is a potentially malignant disorder of the oral mucosa which has to be correctly diagnosed as either OLP or OLL, since the risk of malignancy of these subtypes is significantly different.

Abstract
Oral lichen planus (OLP) is one of the most common chronic inflammatory oral mucosal diseases with T-cell-mediated immune pathogenesis. In subepithelial and lamina propria of OLP local lesions, the presence of CD4(+) T helper (CD4(+) Th) cells appeared as the major lymphocytes. These CD4(+) T lymphocytes can differentiate into distinct Th cell types such as Th1, Th2, Treg, Th17, Th22, Th9, and Tfh within the context of certain cytokines environment. Growing evidence indicated that Th1/Th2 imbalance may greatly participate into the cytokine network of OLP immunopathology. In addition, Th1/Th2 imbalance can be regulated by the Treg subset and also greatly influenced by the emerging novel CD4(+) Th subset Th17. Furthermore, the presence of novel subsets Th22, Th9 and Tfh in OLP patients is yet to be clarified. All these Th subsets and their specific cytokines may play a critical role in determining the character, extent and duration of immune responses in OLP pathogenesis. Therefore, we review the roles of distinct CD4(+) Th subsets and their signature cytokines in determining disease severity and susceptibility of OLP and also reveal the novel therapeutic strategies based on T lymphocytes subsets in OLP treatment.

Abstract
Lichen planus is a chronic mucocutaneous inflammatory disease, which frequently affects the oral mucosa of white females over 40 years old. Its aetiology remains uncertain and the pathogenesis is still the object of much speculation. The present paper presents the most well known antigens, and describes the action of different cells and proteins associated with the development of that disease, as well as the possible agents involved with its malignant transformation. Different external agents, especially virus, and internal agents, like stress, and the heat shock protein antigen expression, associated or not, can alter the basal keratinocytes of the oral mucosa making them susceptible to apoptosis by CD8(+) cytotoxic T cell as well as activate matrix metalloproteinase and mast cell degranulation, which produce a great range of inflammatory mediators and cytokines determining the clinical onset of the disease. Regarding carcinogenesis, since it is a complex process and presents multifactorial origin, it is believed that there may be a synergism between intrinsic, such as inflammation mediators, and extrinsic agents (tobacco, alcohol, viral infections) for the OLP malignant transformation to occur. However, further studies are needed to better understand the origin, pathogenesis and process of malignant transformation of OLP.

Abstract
OBJECTIVE The relationship between hepatitis C virus and Lichen Planus have been widely reported in the literature; although there are wide geographical variations in the reported prevalence of hepatitis C virus infection in patients with lichen planus. This study seeks to determine the prevalence of hepatitis C virus among lichen planus patients and its clinical morphological type in the University of Abuja Teaching Hospital, Gwagwalada Abuja, Nigeria. MATERIALS/METHODS This study was conducted between January 2010 and December, 2011 at the out patients Dermatological unit of the department of medicine at the University of Abuja Teaching Hospital Gwagwalada Abuja, Nigeria. Consecutive patients who had body eruptions suspected to be lichen planus were recruited and histology done for confirmation. The control group included patients' relations and some dermatology patients known to have low risk of hepatitis C virus infection and liver function tests done for both subjects and control after obtaining oral consent from them to participate in the study. RESULT Anti- HCV antibodies were detected in nine cases (21.4%) and one case (3.3%) in the control group. This was statistically significant difference between the HCV antibody among the subject and control group (P<0.038). Hypertrophic lichen planus was the most frequent clinical type. Liver function test was not statistically significant among the subject and control group. CONCLUSION Lichen planus and Hepatitis C virus appear to have a relationship and the prevalence rate was higher among the subject as compared to the control group in our environment.

Abstract
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 transformation and the optimum management of patients to ensure the early diagnosis of transformation. Consensus remains elusive, and leading workers in this field have recently published conflicting reports on the malignant potential of OLP and on the important question of the advisability of excluding patients with epithelial dysplasia or a tobacco habit from studies on this issue. The present review outlines these debates and proposes a possible a molecular basis for the malignant transformation in this disease.

Abstract
Some of the most frequent extrahepatic manifestations of hepatitis C virus (HCV) infection involve the oral region predominantly or exclusively. Part 2 of this review discusses the current evidences regarding the association of lichen planus (LP) and other diseases frequently involving the oral cavity with HCV. Epidemiological data suggest that LP may be significantly associated with HCV infections especially in southern Europe and Japan but not in northern Europe. These geographical differences are possibly influenced by immunogenetic factors, the duration of the HCV infection and the design of the published studies. Because of the fact that most of the studies published are retrospective, it is impossible to establish whether the HCV exposure occurred earlier to or after the onset of disease and more prospective studies are clearly warranted. As the virus may replicate in the skin and oral mucosa and HCV-specific T lymphocytes can be found in the oral mucosa of patients with chronic hepatitis C and LP, HCV may be implicated in the pathogenesis of LP. However, little attention has been paid to the variable effect of therapy with interferon-alpha (IFN-alpha), with or without ribavirin for LP. Conversely, it is unlikely that other oral diseases such as oral carcinoma, pemphigus and Behcet disease are triggered by HCV.

Abstract
AIM: To assess the prevalence of extrahepatic manifestations in Bulgarian patients with chronic hepatitis C virus (HCV) infection and identify the clinical and biological manifestations associated with cryoglobulinemia.
METHODS: The medical records of 136 chronically infected HCV patients were reviewed to assess the prevalence of extrahepatic manifestations. Association between cryoglobulin-positivity and other manifestations were identified using χ2 and Fisher’s exact test. Risk factors for the presence of extrahepatic manifestations were assessed by logistic regression analysis.
RESULTS: Seventy six percent (104/136) of the patients had at least one extrahepatic manifestation. Clinical manifestations included fatigue (59.6%), kidney impairment (25.0%), type 2 diabetes (22.8%), paresthesia (19.9%), arthralgia (18.4%), palpable purpura (17.6%), lymphadenopathy (16.2%), pulmonary fibrosis (15.4%), thyroid dysfunction (14.7%), Raynaud’s phenomenon (11.8%), B-cell lymphoma (8.8%), sicca syndrome (6.6%), and lichen planus (5.9%). The biological manifestations included cryoglobulin production (37.5%), thrombocytopenia (31.6%), and autoantibodies: anti-nuclear (18.4%), anti-smooth muscle (16.9%), anti-neutrophil cytoplasm (13.2%) and anti-cardiolipin (8.8%). All extrahepatic manifestations showed an association with cryoglobulin-positivity, with the exception of thyroid dysfunction, sicca syndrome, and lichen planus. Risks factors for the presence of extrahepatic manifestations (univariate analysis) were: age ≥ 60 years, female gender, virus transmission by blood transfusions, longstanding infection (≥ 20 years), and extensive liver fibrosis. The most significant risks factors (multivariate analysis) were longstanding infection and extensive liver fibrosis.
CONCLUSION: We observed a high prevalence of extrahepatic manifestations in patients with chronic HCV infection. Most of these manifestations were associated with impaired lymphoproliferation and cryoglobulin production. Longstanding infection and extensive liver fibrosis were significant risk factors for the presence of extrahepatic manifestations in HCV patients.

Abstract
Hepatitis C Virus is associated with a wide series of extrahepatic manifestations. Based on available data the link between the virus and some of these extrahepatic diseases is only suggested and needs further confirmation. Hepatitis C Virus-related lymphoproliferative disorders, whose prototype is mixed cryoglobulinaemia, represent the most closely related extrahepatic manifestations of Hepatitis C Virus. Other Hepatitis C Virus-associated disorders include nephropathies, thyreopathies, sicca syndrome, idiopathic pulmonary fibrosis, porphyria cutanea tarda, lichen planus, diabetes, chronic polyarthritis, cardiopathy and atherosclerosis. A pathogenetic link between Hepatitis C Virus and some extrahepatic manifestations was confirmed by their responsiveness to antiviral therapy, which is now deemed the first therapeutic option to consider. By contrast, there are diseases where treatment with interferon was ineffective or dangerous. The aim of the present paper is to outline the most recent evidence concerning extrahepatic disorders that are possibly associated with Hepatitis C Virus infection. Special emphasis will be given to discussion of the most appropriate clinical approaches to be adopted in order to diagnose, treat (possibly prevent) and follow-up extrahepathic diseases in patients with Hepatitis C Virus infection.

Abstract
BACKGROUND Artificial separation of oral mucosa into epithelium and connective tissue represents the first step in investigating both the basement membrane zone and its two components (epithelium and connective tissue) separately. It is a useful tool in analysing the possible role of hepatitis C virus in the pathogenesis of oral lichen planus (OLP). The aim of the present study was to test different methods to separate the epithelium from the connective tissue of oral mucosa affected by OLP as a preliminary step for further immunohistochemical or molecular investigations. PATIENTS AND METHODS Fourteen tissue biopsies of the oral mucosa of clinically and histopathologically confirmed OLP lesions underwent epithelial connective separation (ECS) using six different reagents. RESULTS AND CONCLUSIONS Among the separation methods tested, CaCl2 1 M at 37 degrees C for 30 min, NaCl 1 M at 4 degrees C for 26 h and elastase at 4 degrees C for 22 h allowed good ECS without structural alteration or tissue loss. The present study provides useful information regarding techniques to separate the epithelium from the connective tissue as a preliminary step to investigate oral mucosa affected by OLP from an immunohistochemical or molecular viewpoint.

Abstract
Oral lichen planus (OLP) is a relatively common chronic inflammatory disorder affecting stratified squamous epithelia. Whereas in the majority of instances, cutaneous lesions of lichen planus (LP) are self-limiting and cause itching, oral lesions in OLP are chronic, rarely undergo spontaneous remission, are potentially premalignant and are often a source of morbidity. Current data suggest that OLP is a T cell-mediated autoimmune disease in which auto-cytotoxic CD8+ T cells trigger apoptosis of oral epithelial cells. The characteristic clinical aspects of OLP may be sufficient to make a correct diagnosis if there are classic skin lesions present. An oral biopsy with histopathologic study is recommended to confirm the clinical diagnosis and mainly to exclude dysplasia and malignancy. The most commonly employed and useful agents for the treatment of lichen planus (LP) are topical corticosteroids but other newer agents are available.

Abstract
In recent years an association between oral lichen planus (OLP) and HCV infection has been reported, but the frequency of this association seems to differ in the various geographic areas. It is clear, instead, that some abnormalities occur in the immune-regulation mechanisms of patients with OLP and it is thought to be due to the chronic antigenic stimulus of HCV that causes functional disorders of the immune system in infected patients. Possible immunologic difference between 17 patients with OLP and HCV+ and 17 patients with OLP and HCV- were investigated using standard immunofluorescence and flow cytometry techniques. The distribution of T and B cells was normal in all patients examined, while NK CD56+ cells were increased, above all in HCV- patients. About 65% of T CD4+ lymphocytes coexpressed the CD45RO isoform (p=0.002), while approximately 32% expressed CD45RA, without significant differences in comparison to HCV+ subjects (p>0.05). Moreover, almost all the CD4+CD45RO+ subpopulation coexpressed CD29 in all patients examined. No significant differences between the two groups of patients were detected as to the increase of cytotoxic T CD8+CD57+ lymphocytes. The B cells CD19+CD5+ responsible for the production of "natural" antibodies were detectable in both the examined groups, even if not in all HCV+ subjects (30% +/- 10.1 in HCV- and 27% +/- 19.4 in HCV+ patients; p=0.47). These findings suggest the existence of differences in lymphocyte subpopulations between OLP-HCV+ subjects and OLP-HCV- patients.

Abstract
Oral lichen planus (OLP), an immune-mediated disorder, has been reported as an extra-hepatic manifestation of Hepatitis C virus (HCV) infection, especially in HCV hyperendemic areas such as southern Europe and Japan. The aim of this study was to investigate from an epidemiological standpoint whether HCV infection is an important factor affecting the relative risk of OLP in a Mediterranean population or whether this relates to the degree of HCV endemicity. Two cohorts of OLP patients resident in two different regions of southern Italy (Campania and Sicily; n = 859) were evaluated for HCV infection status and categorized into five age classes to respective region-matched controls. No significant difference was found between OLP patients and the general population in this area, when data were corrected by the age-stratified prevalence of HCV. Therefore, the age-specific prevalence of HCV infection in OLP patients shows a close trend of direct association with increasing age, without significant differences with the general population of each geographical area. An aetiological link between OLP and HCV cannot be inferred solely by epidemiological data.

Abstract
OBJECTIVE The reported frequency of chronic liver disease, and particularly, Hepatitis C virus (HCV) infection in patients with oral lichen planus (OLP) shows geographical variation. The aim of this study was to determine the prevalence of chronic hepatic disease, Hepatitis B virus and HCV infection in patients with OLP and control subjects resident in Serbia. PATIENTS AND METHODS In this prospective study 48 patients with OLP (33 women and 15 men, with a mean age of 49.7 years) and 60 control subjects (38 women and 22 men, with a mean age of 46.7 years) were examined for the presence of serological evidence of chronic hepatic disease, Hepatitis B surface antigen (HBsAg) and anti-HCV seropositivity. RESULTS All patients with OLP had normal liver function. HBsAg was not found in any of the patients with OLP or control group. None of the patients with OLP or control subjects were HCV seropositive. CONCLUSION Patients with OLP resident in Serbia do not have evidence of chronic liver disease or infection with HBV or HCV. The exact aetiological role between hepatic disease and OLP remains unclear.

Abstract
OBJECTIVES We sought to assess the age-specific prevalence of oral lichen planus (OLP) in Mediterranean patients with chronic hepatitis C virus (HCV) and to evaluate the features of OLP in relation to sex, smoking, HCV genotype, HIV-1 coinfection, and antiviral treatments. METHODS In all, 178 anti-HCV-positive adults (60 women and 118 men; age range 20-66 years) recruited from two cohorts (104 HIV-negative patients and 74 patients with HIV coinfection) underwent oral examination. RESULTS Overall prevalence of OLP was 2.8% (5 of 178) (male/female ratio 0.2; odds ratio=0.119; 95% confidence interval=0.013-1.106), only among HIV-negative participants, always in the reticular pattern, and in the adult age. HCV genotype, tobacco smoking, and treatment (interferon alfa/ribavirin) were not significantly associated to OLP. CONCLUSIONS Among HCV-infected patients, we found a low prevalence of OLP. The absence of OLP in HIV-coinfected patients suggests immunosuppression secondary to defective CD4 functions.

Abstract
INTRODUCTION The relationship between hepatitis C virus (HCV) infection and oral lichen planus (OLP) remains a matter of controversy. It is important to determine whether there is an association between OLP and HCV infection so that guidelines regarding the routine HCV testing of patients with OLP can be developed for clinicians. OBJECTIVES The objective of this article was to review and summarize the published literature on the association between OLP and HCV and to describe future directions. METHODS A search of the computerized database MEDLINE (1966-June 2003) was conducted. The bibliographies of articles identified by means of MEDLINE were also searched. Any studies reporting the prevalence of HCV in a group of patients with LP either with or without a control group were included in this review. Also included were studies comparing the clinical and histologic features of LP among patients with and without HCV infection, studies on the presence of HCV within LP lesions, and studies of HCV genotypes among patients with LP. RESULTS Thirty-two studies conducted in various parts of the world were identified. Study types included prevalence studies on HCV exposure among patients with OLP (0%-62%), prevalence of OLP among patients with HCV infection (1.6%-20%), and case-control studies of this association. In addition, the results from 3 studies on the replication of HCV in the oral mucosa, 3 studies on the genotype of HCV in OLP patients, and 4 studies comparing the clinical and histologic features of OLP in HCV-infected and uninfected individuals have been summarized. CONCLUSION At present, studies on the association of OLP and HCV provide enough information to raise a number of interesting questions about this association. Important biases-including selection bias; investigator bias due to lack of blinding and the possible resultant nondifferential misclassification of disease; and possible confounding by age in the studies published-make it difficult to draw firm conclusions. However, the need for future studies that take into consideration all these factors in the study methodology is highlighted by this review.

Abstract
BACKGROUND Oral lichen planus (OLP) is a chronic inflammatory disease which is recalcitrant to medical treatment. The purpose of this study was to compare the effectiveness of various forms of the topical steroid fluocinolone acetonide applications in patients with OLP. METHODS Data of OLP patients were collected retrospectively from the chart record and the 97 OLP patients were divided into three groups. The first group (n = 28) was treated with a 0.1% solution of fluocinolone acetonide (FAS), the second group (n = 22) with 0.1% fluocinolone acetonide in orabase (FAO), and the third group (n = 47) with both FAS and FAO (FAS/FAO) throughout the study. Each group was clinically evaluated as complete remission (CR), partial remission (PR), or no response (NR), following the treatment. Also, the side-effect of oral candidiasis was recorded in each group. RESULTS Two years of treatment resulted in complete remission of 77.3, 21.4, and 17.0% of patients in the FAO, FAS, and FAS/FAO groups, respectively. There was a statistically significant difference in disease remission (P < 0.05), but not in oral candidiasis appearance (P > 0.05) among various forms of topical steroid application. CONCLUSION The study concluded that FAO or FAS can produce improved results in the management of OLP by long-term follow-up.

Abstract
Morbidity associated with hepatitis C virus (HCV) infection can involve a variety of extrahepatic conditions, including lichen planus (LP) and sialadenitis, predominantly or exclusively involving the oral region, conditions which have been largely neglected in reviews. The literature suggests that HCV-infected patients may frequently have Sjögren-like sialadenitis with mild clinical symptoms, whereas oral LP may be significantly associated with HCV infections in Southern Europe and Japan but not in Northern Europe. These geographical differences could be related to immunogenetic factors such as the HLA-DR6 allele, significantly expressed in Italian patients with OLP and HCV. Analysis of experimental data suggests that HCV could be involved in the pathogenesis of both these diseases. Moreover, parotid lymphoma may arise in patients with sialadenitis, mainly with type II cryoglobulinemia. Little attention has been paid to oral health needs in HCV-infected patients and the variable effect of interferon-alpha therapy on oral tissues. Further research is needed, because of the potentially great influence of oral diseases possibly linked to HCV on the quality of life of millions of patients.

Abstract
The purpose of this study was to examine the association of dental materials with oral lichen planus (OLP) and, particularly, the effects of amalgam, amalgam corrosion status, gold and dissimilar metals in continuous contact. A case-control study was performed with 43 OLP cases from the Oral Medicine Clinic at the School of Dentistry, University of Washington and 78 controls from a general dental care-screening clinic, also at the School of Dentistry, University of Washington. Health histories and oral examinations were obtained. Current metal or metal-based restorations were charted, along with corrosion status of amalgams and the presence of dissimilar metals in continuous contact. Adjusted odds ratios (ORs) and 95% confidence intervals for the following potential risk factors were found to be: (1) number of teeth with amalgam, OR = 1.02 (0.92, 1.13); (2) total surfaces of amalgam, OR = 0.96 (0.92, 1.0); (3) number of teeth with gold, OR = 1.12 (0.95, 1.31); (4) mean amalgam corrosion score, OR = 5.74 (2.34, 14.1); (5) presence of dissimilar metals in contact (per quadrant), OR = 1.25 (0.81, 1.92). These findings suggest that although the presence of amalgam or gold themselves is not associated with increased risk of OLP, corrosion of amalgams and the presence of a 'galvanic effect' from dissimilar dental materials in continuous contact (bimetallism) are associated with an increased risk of OLP.

Abstract
Hepatitis C virus infection can be associated with different extrahepatic manifestations, including lichen planus; however, no clear role for HCV in their pathogenesis has been established. T cells were isolated from lichen biopsy specimens of 7 HCV positive patients with oral lichen planus. HCV-specific CD4(+) T-cell lines were obtained in 4 patients from lichen lesions but only in 2 of them from the peripheral blood. Different clonal populations were found in oral tissue and peripheral blood of individual patients, as shown by TCR-Vbeta analysis of antigen-specific T cells. Frequency of HCV-specific CD8(+) cells tested with 4 different HCV tetramers was significantly higher in the lichen tissue than in the circulation; moreover, lichen-derived HCV-specific CD8(+) T cells showed the phenotype of recently activated T cells because most of them were CD69(+) and produced interferon gamma (IFN-gamma) but expanded poorly in vitro upon antigen stimulation. The specificity of HCV-reactive T-cell recruitment into the lichen tissue was further confirmed by the absence of HBV-specific T cells within lichen lesions in 3 additional patients with lichen planus associated with HBV infection. Our study shows HCV-specific T-cell responses at the site of the lesions of an HCV-associated dermatologic disease, sustained by HCV-specific T cells with phenotypic and functional characteristics of terminally differentiated effector cells. In conclusion, this finding and the detection of HCV RNA strands in the lichen tissue strongly suggest a role for HCV-specific T-cell responses in the pathogenesis of oral lichen planus associated with HCV infection.

Abstract
BACKGROUND/AIMS Patients infected with the hepatitis C virus (HCV) often have extrahepatic manifestations, which significantly contribute to HCV-related morbidity, but whose pathogenesis is largely unknown. Our aim was to evaluate the HCV replication in oral mucosa of chronic hepatitis C patients. METHODS We collected oral mucosa specimens from 17 anti-HCV-positive and four anti-HCV-negative patients. Fifteen had oral lichen (12 anti-HCV-positive). Total mucosa RNA was extracted and analyzed for presence and titer of genomic and negative-strand HCV RNA. Findings were compared with clinical and pathological features. RESULTS Genomic and negative-strand HCV RNA were detected, respectively, in 12 of 17 (70.6%) and four of 17 (23.5%) specimens from the chronic hepatitis C patients. No negative-strand HCV RNA was detected in five anti-HCV-positive patients without lichen (including three with normal mucosa). Presence and titer of the negative-strand HCV RNA were independent of HCV genotype, serum viral load, and histological diagnosis of liver lesions. The phylogenetic analysis of the envelope 2 region cloned from a normal mucosa and the corresponding serum further suggested that only lichen tissues appear to harbor replicating HCV. CONCLUSIONS HCV may occasionally replicate in oral lichen tissue, possibly contributing to the pathogenesis of mucosa damage.

Abstract
The reported prevalence rate of anti-hepatitis C virus (HCV) antibodies in patients with oral lichen planus shows wide geographical variation and ranges from 0 to 65%. Certain characteristic clinical features have been attributed to oral lichen planus associated to HCV infection. The purpose of this investigation has been to assess hypothetical clinical differences, as well as differences in the intensity of the subepithelial inflammatory infiltrate between oral lichen planus-HCV +ve patients and oral lichen planus-HCV -ve patients. A total of sixty-two patients entered the study. Their mean age was 63.5 +/- 14.49 years, and 48.4% of them were men and 51.6% women. Patients were classified according to their serum HCV positivity. Age, sex, clinical presentation (reticular or atrophic-erosive), extension of the lesions, location of the lesions, number of locations affected, intensity of the inflammatory infiltrate and Candida albicans colonization were recorded for each patient. Reticular lichen planus was the most frequent clinical presentation in both HCV +ve (57.1%) and HCV -ve patients (63.6%). C. albicans colonization ranged from 42.8% in HCV +ve and 41.7% in HCV -ve patients. HCV + ve patients showed certain oral locations more frequently affected than HCV -ve ones: lip mucosa, 28.6% versus 7.3%; tongue, 57.1% versus 29.1%; and gingiva, 71.4% versus 23.6%. The number of affected intraoral locations was higher in HCV +ve patients (71.4%) than among HCV -ve ones (20.4%; chi2 = 8.34; P < 0.011). No statistically significant differences could be established in terms of density of subepithelial inflammatory infiltrate between the groups. Our results reinforce the need for liver examination in all patients with oral lichen planus, particularly those showing lesions on the gingiva with multiple intraoral locations affected, as no pathological differences could be identified between HCV + ve and HCV -ve patients.
