Background: Multiple studies indicate the correlation between lichen planus (LP) and certain systemic disorders. Data suggest an increased incidence of dyslipidemia with LP. Abnormal lipid levels are major risk factors for developing atherosclerotic changes and cardiovascular disorders (CVD). Non-high-density lipoprotein cholesterol (non-HDL-C) is a reliable marker for cardiovascular events. If non-HDL-C levels are raised in LP patients, it would mean that these individuals are high-risk patients and should be investigated periodically. We aimed to find non-HDL-C serum levels in cases of lichen planus and compare them with controls.Methods: We compared lipid profiles between 100 cases of LP and 50 healthy controls.Results: Non-HDL-C levels were significantly higher in cases than controls (P = 0.002). The non-HDL-C level was elevated in 67% of LP cases, compared to 42% of controls.Conclusions: We demonstrated higher levels of non-HDL-C in LP patients than in controls, confirming the increased risk of CVDs in LP patients.

Background: Lichen planus (LP) is a chronic inflammatorydisorder involving the skin, mucosa, hair, and nails. Previousreports have shown a possible association between LP andmetabolic derangement, leading to increased cardiovascular riskamong these patients. Our study aimed to assess the prevalenceof metabolic syndrome (MetS) and its components in LP patientsand to study their relationship with mucosal involvement in LP.Methods: We conducted a cross-sectional observational study of123 LP patients. Demographic and clinical data were obtained,and evaluation was done for the presence of abdominal obesity,hypertension, hyperglycemia, and dyslipidemia. MetS wasdiagnosed according to the modified National CholesterolEducation Program: Adult Treatment Panel III (NCEP-ATP III)criteria for the South Asian population. Data analysis was doneusing appropriate statistical methods.Results: The prevalence of MetS in LP patients was 31%. The meanage of LP patients having MetS was considerably higher thanthose without MetS (44.8 ± 13.6 vs. 33.3 ± 15.9 years; P = 0.0002).Although statistically insignificant, female patients and patients withmucosal involvement showed a higher prevalence of MetS. Centralobesity, hypertension, hyperglycemia, and hypertriglyceridemiawere more prevalent in mucosal LP patients than in those withoutmucosal lesions, with hyperglycemia having a significantly higherprevalence in mucosal LP (41% vs. 18%; P = 0.015).Conclusion: Incre ased age, female gender, and mucosalinvolvement are important predictors of concurrent metabolicderangement in LP patients. Thus, these patients should bescreened for the presence of MetS and its components.

Background: The increased prevalence of metabolic syndrome has been established in chronic inflammatory skin diseases. Patients with metabolic syndrome have a higher mortality rate due to cardiovascular disease and malignancy. In this study, the prevalence of metabolic syndrome was evaluated in lichen planus patients compared with a control group in Kerman, southeast Iran.Methods: This was a cross-sectional study on 90 patients with lichen planus and 90 healthy participants from the Dermatology Clinic of Afzalipour Hospital, Kerman, Iran. Demographic features of the patients and clinical features of the lesions were recorded. Then, parameters of metabolic syndrome were evaluated in both groups. The independent t-test and chi-squared test were used to compare quantitative and qualitative variables, respectively.Results: There was no significant difference in demographic features of the participants between the two groups. Metabolic syndrome was significantly more prevalent in the lichen planus group (62.6%) than in the control group (14.4%) (P = 0.001). Metabolic syndrome parameter values (except waist circumference) were significantly higher in the lichen planus group than in the control group. Lichen planus patients with metabolic syndrome had a significantly higher percentage of mucosal involvement (66.1%) than lichen planus patients without metabolic syndrome (44.1%). Lichen planus patients with metabolic syndrome were significantly older than those without metabolic syndrome.Conclusions: This study observed a higher prevalence of metabolic syndrome in lichen planus patients relative to controls. Furthermore, lichen planus patients with metabolic syndrome had significantly higher age, mucosal involvement, and body mass index than lichen planus patients without metabolic syndrome.

Background: Lichen planopilaris (LPP) is the most common form of immune-mediated scarring alopecia. We evaluated the histopathologic features of LPP in vertical sections of scalp biopsies and compared findings between the scarring and nonscarring phases of the disease.Methods: From June 2019 to June 2020, vertically sectioned scalp biopsies of 70 new cases of LPP were examined (H&E) according to North American Hair Research Society criteria. Furthermore, patients were divided into two groups based on either the presence or the absence of vertical fibrous bands, and other histopathological features were compared between these two groups.Results: Characteristic findings of LPP were perifollicular lymphocytic infiltration (97.1%), follicular interface degeneration (60%), and perifollicular plasmacytic infiltration (21.4%). Vacuolar degeneration in the dermo-epidermal junction (38.6%), perifollicular lamellar fibroplasia (67.1%), loss of sebaceous glands (87.1%), perifollicular cleft formation (28.6%), and vertical fibrous tracts (65.7%) were also found. Furthermore, we found a significant correlation between the presence of fibrous tracts with both loss of sebaceous glands (P = 0.005) and the presence of lamellar fibroplasia (P = 0.015).Conclusion: The most common findings in the histopathological examination of LPP slides are perifollicular lymphocytic infiltration and loss of the sebaceous glands. Furthermore, sebaceous gland loss and perifollicular lamellar fibroplasia correlate with the scarring phase of LPP.

Radiation therapy is frequently associated with a variety of adverse cutaneous effects. Some of these complications, such as radiodermatitis, are well known. However, some other skin reactions, such as radiation-induced lichen planus (LP) as a kind of isoradiotopic response, are rare, less known, and often underrecognized. An isoradiotopic response refers to the appearance of a secondary dermatosis in previously irradiated areas. In an isoradiotopic response, the new skin lesion presents with all the hallmarks of the primary dermatosis; however, the eruption is restricted to the field of radiation therapy. Radiation-induced LP as a kind of isoradiotopic response refers to the appearance of LP lesions in previously irradiated areas. This article presents a narrative review of the current literature about radiation-induced LP cases. The search was conducted on electronic databases, including PubMed, Web of Science, Cochrane, Scopus, Medline, Embase, and Google Scholar with the keywords, “isoradiotopic response,” “isotopic response,” “Koebner phenomenon,” “lichen planus,” “cancer treatment,” “radiotherapy,” and “radiation therapy.” According to the results of this search, there were only nine case reports of radiation-induced LP in the literature. Due to the limited number of articles published in this field, there are important questions, the answers of which are not known yet. By reporting more patients with post-radiation LP, investigators will be able to gather more information about the pathogenesis of the disease and evaluate the significance of different factors in the development of post-radiation LP.

Background: Since its recognition, frontal fibrosing alopecia (FFA) has increasingly been studied globally in terms of its diverse aspects. Having found no studies describing this condition in Southern Iran, we examined the different clinicopathological features of patients with FFA who referred to Faghihi Hospital, Southern Iran, between 2013 and 2018. Methods: We searched the archives of the Pathology Department of Faghihi Hospital for the cases with a diagnosis of FFA. Due to its similar histopathologic features with lichen planopilaris, the final diagnosis was made using clinical correlations. Results: Twenty-two patients were enrolled; all were female. Fifteen (68.2%) presented with the disease before menopause. Besides frontal and/or temporal hairline involvement in all the patients, eyebrow alopecia, eyelash loss, body hair loss, and facial papules were present in 81.8%, 27.3%, 50%, and 68.2% of them, respectively. Dermoscopic findings included follicular opening loss (100%), honeycombing of the scalp (81.8%), multiple white dots (77.3%), perifollicular erythema (63.6%), and perifollicular scales (59.1%). The histopathologic examination revealed follicular dropout (95.4%), perifollicular lymphocytic infiltration in the infundibulum and isthmus of the follicles (81.8%), perifollicular fibroplasia (77.3%), intact interfollicular epidermis (59.1%), mild perivascular lymphocytic infiltration in the upper dermis (54.5%), and apoptotic keratinocytes in the infundibulum and isthmus (50%). The most common comorbidity was hypothyroidism (40.9%). Conclusions: Thediagnosis of FFA should be considered in both premenopausal and postmenopausal women. Eyebrow alopecia, eyelash loss, body hair involvement, and facial papules are helpful clues in the diagnosis. The coexistence of hypothyroidism with FFA suggests immunological involvement in the pathogenesis.

Lichen planus pigmentosus (LPP) develops as an asymptomatic and dusky pigmentation of the facial skin with no effective treatment. Herein we report a 54-year-old lady with clinical and histopathologic confirmation of LPP who was scheduled to be treated with CO2 laser resurfacing. After tumescent anesthesia, the whole facial skin was treated with three passes of Ultrapulse conventional CO2 ablation. The energy used in the first, second, and third passes were 6.6, 5.4, and 4.8 mJ, respectively. The mandibular area was treated with two passes (4.2 and 3.6 mJ). The eye contours were treated with two passes (3.9 and 3.3 mJ). The patient’s face remained edematous for a week, with the facial skin oozing within the first three days before it became crusted. The crust shed out from day three to six. After a week, smooth and erythematous skin appeared. The erythema persisted for up to four months, after which uniform skin with considerable bleaching and rejuvenation developed. No recurrence occurred within 18 months of follow-up. We conclude that LPP can be treated with CO2 laser resurfacing without any complications.

Background: Lichen planus is a chronic inflammatory disease associated with an increased risk of subclinical atherosclerosis and cardiovascular diseases. This study aimed to evaluate patients with lichen planus using carotid Doppler ultrasound parameters.Methods: Forty patients with lichen planus and 40 controls were included in this study. Common carotid artery intima-media thickness (CIMT) and the number of atherosclerotic plaque weremeasured and compared to the control group. Total cholesterol, triglyceride, low-density lipoprotein (LDL) and high-density lipoprotein (HDL) levels were measured. Leptin level (Pg/ml)was measured using the enzyme-linked immunosorbent assay (ELISA) method (Leptin ELISA kit, Orgenium, Finland).Results: Significant difference was found between the groups in terms of CIMT (P=0.005). The median range for blood leptin level, triglyceride, cholesterol, and LDL was higher for lichen planus patients than for controls. We found a significant difference between the severity of LP and CIMT (P=0.035). No statistical difference was found between LP and the number of atherosclerotic plaque.Conclusions: Our study suggested that measurement of the mean intima media wall thickness of the common carotid artery could be beneficial as a valuable method for early diagnosis of atherosclerosis in lichen planus.

Background: Lichen planus (LP) is a chronic inflammatory disease involving the skin, mucous membranes and appendages. Like other chronic inflammatory diseases, it may be associated with metabolic disorders and dyslipidemia. Due to the discrepancies in the results of previous studies and lack of a similar study on an Iranian population, we decided to investigate and compare the serum lipid levels of LP patients and normal healthy subjects.Methods: In this case-control study, 71 patients with lichen planus confirmed by clinical and pathological examination who referred to dermatology clinic were recruited; further included were 71 subjects selected from attendants without any skin diseases matched for age, gender and BMI.with patients; the well-being of the healthy subjects was confirmed by laboratory tests, physical examination and medical history..After filling the questionnaire, triglyceride, cholesterol, HDL and LDL levels were measured for patients and healthy subjects..The collected data were then analyzed.Results: Mean age of patients in the case group was 40.63 ± 11.41 years, 50.6% of whom were men, while 49.4% were women. Cholesterol, triglyceride and LDL levels in patients were significantly higher than the control group; it was only regarding HDL levels that no significant difference was observed between the two groups. HDL and triglyceride levels were significantly higher in patients with generalized disease. There was a recognizable correlation between elevated levels of LDL and cholesterol and disease duration.Conclusions: In this study, a disrupted lipid profile was observed in LP patients, which can be associated with disease severity. This study proposes measuring lipid serum levels prior to commencing the treatment in all known cases of lichen planus so as to preclude cardiovascular diseases if there is a problem with the lipid profile.

Background: Oral lichen planus (OLP) is a common inflammatory disease of unknown origins. Recent studies have considered nutritional factors concerning the pathogenesis of many autoimmune disorders. The objective of the present study was to investigate the plasma levels of magnesium (Mg), calcium (Ca), zinc (Zn), copper (Cu), and iron (Fe) in this disorder. Methods: Included in this observational case-control study was 40 patients with OLP and 40 age and sex matched healthy control subjects. Plasma levels of Mg, Ca, Zn, Cu, and Fe were specified using an autoanalizer. Results: The serum level of Ca was higher, but Mg, Cu, Fe and Zn serum concentration did not differ significantly between the patients with OLP and the healthy controls. Mean Zn concentration was lower in patients with erosive lichen planus compared to the non-erosive group and the healthy controls. However, only the difference between erosive lichen planus patients and healthy participants was significant. The mean Zn level was lower than the normal range (70 µg/dl) in both the cases and controls. The concentration of Fe was significantly higher in men male patients than in females; however, the difference between men and women was not significant in the healthy control group. The mean Cu/Zn ratios in erosive and patient groups were slightly higher compared with the controls. Conclusion: Trace elements such as Ca may play a role in the ethiopathogenesis of OLP. Nevertheless, other elements such as Zn or Cu may influence OLP, which requires further evaluation on larger samples.

Background: Lichen planus (LP) is a chronic inflammatory skin condition which leads to changes in lipid metabolism. It may cause chronic atherosclerosis and metabolic syndrome. Theobjective of this study is to compare lipid levels of patients with LP to healthy controls. Methods: This case-control study recruited 100 total participants, 50 (25 male and 25 female) patients with LP and 50 healthy controls admitted to the Dermatology Clinic of Imam Hospital, Ahvaz, Iran. Serum triglyceride, total cholesterol, HDL cholesterol, and LDL cholesterol levels were measured in samples drawn after a 12-hour fasting period. Results: Patients with LP had significantly higher triglycerides (147.7 vs. 118.4 mg/dl, P<0.05), total cholesterol (188 vs. 173 mg/ dl, P<0.05), LDL (122 vs. 106 mg/dl, P<0.05), and lower HDL (49 vs. 57 mg/dl, P<0.05) levels compared to controls. Conclusion: This study showed an association between LP and dyslipidemia. Screening of serum lipids in patients with LP might be valuable to prevent cardiovascular diseases.

Background: Lichen planus is a common inflammatory disease that can involve the skin, nails, mucous membrane, and hair follicles. There is a long list of topical and systemic therapies for its treatment. Methotrexarte has some characteristics that make it a good choice for generalized lichen planus. Aim: The goal of this study was to assess the effect of low dose methotrexate in generalized lichen planus. Method: Eighteen patients (8 male and 10 female, mean age: 51.1, range: 22-80, SD: 14.9) with generalized lichen planus were enrolled in the study. After basic evaluations, low dose methotrexate (7.5-10 mg weekly) initiated. The response rate was appraised after 2, 4 and 8 weeks. Six-month follow-up was done for evaluating the recurrence rate. Result: At the end of the 8th week, 75% of the patients had more than 75% improvement. After six months, no case of recurrence was reported. Adverse effects were limited to laboratory abnormalities in two patients (abnormal liver function tests in one case and decreased hemoglobin in the other case). Conclusion: Low dose methotrexate is a very good and safe treatment for generalized lichen planus, especially when there is concern regarding the steroids undesired effects or when the disease is resistant to corticosteroids.

Twenty Nail Dystrophy (TND) is a rare acquired idiopathic nail dystrophy characterized by excess longitudinal ridging, distal notching, splitting, loss of nail luster and thinning of nail plates that may affect 1 to 20 nails. It occurs as a common manifestation of various dermatoses affecting the nail unit like lichen planus, psoriasis, atopic dermatitis, onychomycosis, vitiligo and alopecia areata, but isolated cases without an associated disease are rare. TND is a manifestation of diverse underlying processes; therefore its histology will vary; however, histologic data on TND are only available in very few published reports. We are documenting the histologic features of TND in a 12-year-old boy who presented with thin rough opaque lusterless nail plates with longitudinal ridging of the twenty nails without any systemic involvement.

Lichen planus pemphigoides (LPP) is a rare autoimmune blistering disease that is characterized by the development of vesico-bullous skin lesions in patients with lichen planus. The histopathology of LPP reveals a sub_epidermal blister with linear deposition of IgG and /or C3 along the dermal_epidermal junction (DEJ) upon direct immunofluorescence (DIF). We hereunder describe a case of lichen planus pemphigoides in a 69-year-old otherwise healthy male who initially presented with typical lesions of lichen planus (LP), predominantly on the lower extremities; then, bullous lesions developed on the normal skin.

Vitiligo and Lichen Planus, two common dermatologic disorders, are expected to coexist. This leads to diverse theories regarding their immunopathogenesis linkage. In this case, we report a twenty-year-old man suffering from simultaneous lichen planus and vitiligo which were both generalized at the time of observation and also concomitant throughout their entire course of progression. Lichen Planus papules were located on sun-exposed areas and non sun-exposed areas; both on vitiligenous areas and non-vitiligenous areas diminishing current theories about the association of the two diseases. Since we did not have the patient’s consent to perform a series of biopsies, we were unable to evaluate dermatopathology of the two diseases at different sites in regard to sun exposure. Further extensive researches on larger scales seem warranted to propose any kind of theory regarding their interconnection.

Background: Lichen planus is a common dermatological condition. Many treatment options have been discussed in literature, each with its own risk profile. Betamethasone pulse therapy is one of the effective therapies mentioned.The objective of this study was to find out whether oral betamethasone mini pulse therapy is effective in lichen planus.Methods: A total of 40 patients were enrolled in the study. Twenty patients received 5mg of oral betamethasone daily for two consecutive days in a week for 6 weeks along with loratadine and the other twenty patients received a loratadine tablet daily for the same period.Results: The flattening of the existing lesions, appearance of the new lesions and persistence of itching were considered as the parameters of clinical evaluation. It was clearly observable that the number of lichen planus lesions were drastically decreasing in group A and only slightly increasing in group B during the follow-ups.Conclusion: Betamethasone oral mini-pulse therapy was found to be more effective than loratadine in the treatment of lichen planus.

Background and aim: Lichen planus (LP) is an inflammatory papulosquamous disease that affects skin, mucous membranes, nails and hair. As the disease presents in various clinical types, the objective of this study was to determine the frequency of clinical variants of LP in dermatological out-patients in Kerman. Materials and methods: In this study 300 patients with LP were evaluated during 1382-83 in dermatological out-patients in Kerman. Diagnosis was based on clinical features and skin biopsy. The demographic features including age, sex, and the clinical pictures of the disease including clinical types, site of involvement, duration of the disease and associated diseases were assessed. The hepatitis B surface antigen, anti hepatitis B core antibody, hepatitis C antibody and liver function tests were measured. Results: Patients consisted of 167 men (55.5%) and 133 women (44.5%) with a mean age of 32.4 years and a mean duration of 11.6% months. The age of patients ranged from 4 to 78 years, most being in the age range from 30 to 50 years. The majority of patients (70.6%) had classical lesions followed by mucosal (65%), annular (21%), hypertrophic (19%), and lichen nitidus (18%). The dermatomal type obtained the least frequency (2.6%). Upper extremity was the most frequent site of onset (70.6%). Mucosal involvement was observed in 65% and nail and hair changes were observed in 33.6% and 6.6% of patients, respectively. Pruritus was the chief complaint of the majority of patients. Conclusion: Classic LP was the most common type and extremities were the most common site of involvement in this study.

Background and aim: An epidemiological association of lichen planus (LP) with hepatitis C virus (HCV) infection has been found only in certain parts of the world and in some countries no association has been noted. The present study was done to evaluate the association of LP with HCV in patients admitted to Sina hospital, Hamedan, Iran from 2002 to 2004.Materials and Methods: The presence of anti HCV antibody in 32 patients with LP was compared with 43 patients suffering from other dermatoses not related to HCV. Both patient and control groups were screened for the anti HCV antibody using ELISA. The positive cases were tested again using RIBA method. Only confirmed positive cases with the RIBA method, were considered as anti HCV antibody positive.Results: Anti HCV-antibody was positive in 3.1% of patient group (one out of 32) and in 7% of control group (3 out of 43). Conclusion: In Hamedan province no association was found between HCV infection and LP therefore the routine test of LP patients for anti HCV antibody is not necessary.

Background and aim: Cicatrical alopecia refers to lesions associated with permanent destruction of hair follicles. Several diseases such as folliculitis decalvans, lichenplanopilaris (LPP) and discoid lupus erythematosus (DLE) may result in cicatricial alopecia. Since cicatricial alopecia is scarring and affects both the appearance and psychosocial behaviours of the patients and also it can be an alarming sign of some systemic diseases, making an early diagnosis and proper treatment can prevent progression and further complications. The aim of this study was to determine the epidemiologic and clinicopathologic characteristics of cicatricial alopeica.Materials and Methods: A total of 100 patients with cicatricial alopecia were selected from those referred to the skin clinic of Sina hospital in Tabriz for further assessment from 1997 to 2004. Their disease was pathologically proven. All epidermiologic and clinicopathologic data were obtained through questionaires. The results were analysed by means of descriptive statistical methods.Results: Fifty-two of hundred patients were male and 48 were female. The highest incidence rate was found in 3rd, 4th and 5th decades of life. The underlying diseases in descending order were: 30% (24 male, 6 female) had folliculitis decalvans, 25% (10 male and 15 female) had DLE, 18 ( 6 male, 12 female) pseudopelade of Brocq, 14% (4 male and 10 female) had LPP, 8% (4 male, 4 female) had morphea and 5 (4 male , 1 female) had keloidalis folliculitis. From a histo-pathologic point of view, lymphocytic cicatricial alopecia was more common among middle aged women (65%) whereas the neutrophilic type was more prevalent among middle aged men (35%). The ratio of lymphocytic to neutrophilic cicatricial alopecias was 2/1.Conclusion: Considering the high incidence of cicatricial alopecia, early stage diagnosis by biopsy and proper treatment will reduce further progression and especially alleviate psychosocial disturbances.

Background: Lichen planus (LP) is an idiopathic papulosquamous disorder, which can show cutaneous or mucosal signs. It is caused by a cell mediated immune response to an antigen. A wide range of clinical manifestations has been reported. Objective: To determine the sex and age frequency and clinical presentations of this disease in patients referred to Razi hospital in Tehran. Patients and Methods: In this observational case series study, patients referred to Razi hospital in Tehran from May to July 2003 were examined and clinically or clinicopathologically confirmed cases of LP were selected. Results: One-hundred and twenty patients had LP (52 females-68 males). The age range was 6-80 years and the mean age was 40.6 years. Sixty-seven of patients had cutaneous lesions, 20% had mucocutaneous and 13% had mucosal lesions. Hypertrophic LP was present in 22% and typical or classic LP was seen in 18%. Seven percent of patients had scalp involvement and oral LP was present in 33.3% of cases and the most common form was reticular. Genital lesions were present in 6% of cases mainly in male cases and as annular form. Six percent of patients had positive family history of LP. Conclusion: In this study LP was more common in male patients and in fourth decade of life. Hypertrophic LP and classic LP were the most common and reticular form was the most common form of oral LP. Genital lesions were mainly seen in male patients and as annular form.

Actinic lichen planus is a clinical variant of lichen planus, involving mainly sun-exposed areas and manifested as annular lesions with a pigmented center surrounded by a hypopigmented zone. A rare presentation of actinic lichen planus mimics melasma but have distinctive histopathologic picture in favour of actinic lichen planus. Herein, we report a 14-year-old boy who presented with a melasma-like patch on the left side of forehead. Histopathologic findings including pigmentation of basal layer accompanied with vacuolization and also pigmentary macrophages in dermis were in favour of actinic lichen planus.
