- Abstract
Importance: Lichen planopilaris (LPP) is a form of scarring alopecia associated with progressive, permanent hair loss. Symptoms range from burning pain to itching, also carrying substantial psychological morbidity. Yet, disease characteristics, pathophysiology, and effective treatment data are limited, making treatment a challenge., Objective: To describe the prevalence and dermatologist-prescribed treatment patterns of LPP among US adults., Design, Setting, and Participants: This cross-sectional study used the Explorys database. The prevalence analysis used a 15% random sample and identified US adults with LPP diagnoses between 2017 and 2019. The LPP treatment analysis included all patients with LPP diagnoses between 2016 and 2020 and a dermatologist encounter in the first year after diagnosis. Data were analyzed from January 2023 to April 2023., Main Outcomes and Measures: The main outcomes of the prevalence analysis were the crude and standardized prevalence estimates of US adults with LPP across age, sex, and racial groups. The main outcomes of the treatment analysis were the frequency of LPP treatments within 1 year of diagnosis, and the number of patients who continued treatment beyond 1 year, switched treatments, and combined treatments., Results: Among 1 466 832 eligible patients analyzed for prevalence, 241 patients had an LPP diagnosis (222 [92.1%] female; median [IQR] age, 64 [54-73] years). Standardized overall prevalence was 13.4 per 100 000 (95% CI, 11.7-15.1). In the treatment analysis, 991 patients had an LPP diagnosis (907 [91.5%] female; median (IQR) age, 60 [47-69] years). Most received at least 1 type of medication (635 [64.1%]), most frequently intralesional corticosteroids (370 [37.3%]) and topical corticosteroids (342 [34.5%]), followed by doxycycline (104 [10.5%]) and hydroxychloroquine (72 [7.3%]). Treatment continued beyond 1 year in 71 of 200 patients (35.5%) prescribed intralesional corticosteroids and 7 of 29 patients (24.1%) prescribed hydroxychloroquine. Treatment switching at 1 year occurred in 32 of 254 patients (12.6%) first prescribed an intralesional corticosteroid and in 44 of 194 (22.7%) first prescribed a topical corticosteroid. Combinations of 2 or 3 treatment types were given to 137 (13.8%) and 74 (7.5%) patients, respectively., Conclusions and Relevance: This cross-sectional study reported prevalence and treatment patterns for US adults with LPP in a representative sample. Most patients with LPP received treatment, and many received multiple treatment types and switched treatments, suggesting further research into medication selection offers clinical benefit.

- Abstract
Introduction: Lichen planopilaris (LPP) is a common type of primary cicatricial alopecia. Previous studies focused on the epidemiology, clinical characteristics, and treatment of LPP. A lack of knowledge regarding LPP outcomes and prognostic factors remained., Methods: To delineate the rate and timing of remission in LPP, as well as the prognostic factors for achieving remission, a retrospective cohort study was conducted. The study included 126 patients, from a single tertiary center, diagnosed with LPP between January 2010 and December 2022, who were followed up for a minimum of 6 months., Results: There were 89 (70.6%) women and 37 (29.4%) men included in this study. The mean age of the patients was 47.92 ± 14.2 years. The mean time from disease onset to diagnosis was 33.85 (±30) months, indicating significant diagnostic delays. The mean duration of follow-up was 34.13 ± 22.7 months. Among the cohort, 43 patients achieved complete remission (CR) during the follow-up period, whereas 83 patients did not. Of the 83 patients who did not achieve CR, 35 partially improved and 48 did not improve or worsened. The median time for achieving CR was 46 ± 18.8 months. Milder disease at presentation and comorbid lichen planus were associated with higher CR rates., Conclusion: This study demonstrates significant diagnostic delays that should be addressed as LPP causes irreversible alopecia, suggests disease severity and comorbid lichen planus as potential prognostic factors. Further, it emphasizes the limited efficacy of current treatments and the need for prolonged treatment in patients with LPP to achieve remission., (© 2024 S. Karger AG, Basel.)

- Abstract
Background: Various comorbid diseases have been reported in patients with lichen planopilaris (LPP); however, data regarding the risks of incident diseases and mortality are lacking., Objectives: To investigate the risks of incident diseases and mortality associated with LPP., Methods: This was a retrospective nationwide population-based study, using data from the National Health Insurance Service Database of Korea from 2002 to 2019. Patients aged ≥ 18 years with three or more documented medical visits for LPP were included. The adjusted hazard ratios (aHRs) for incident disease outcomes and mortality were compared with 1 : 20 age-, sex-, insurance type- and income-level-matched controls., Results: In total, 2026 patients with LPP and 40 520 controls were analysed. The risks of incident systemic lupus erythematosus [aHR 1.91, 95% confidence interval (CI) 1.21-3.03], psoriasis (aHR 3.42, 95% CI 2.83-4.14), rheumatoid arthritis (aHR 1.39, 95% CI 1.19-1.63), lichen planus (aHR, 10.07, 95% CI 7.17-14.15), atopic dermatitis (aHR 2.15, 95% CI 1.90-2.44), allergic rhinitis (aHR 1.29, 95% CI 1.13-1.49), thyroid diseases (hyperthyroidism: aHR 1.42, 95% CI 1.14-1.77, hypothyroidism aHR 1.19 95% CI 1.01-1.41, and thyroiditis: aHR, 1.35, 95% CI 1.08-1.69), nonmelanoma skin cancer (aHR 2.33, 95% CI 1.00-5.44) and vitamin D deficiency (aHR 1.23, 95% CI 1.03-1.47) were higher in patients with LPP. Patients with LPP had a higher mortality rate than controls (aHR 1.30, 95% CI 1.04-1.61), although the risk was not significant after adjusting for comorbidities (aHR 1.08, 95% CI 0.87-1.34)., Conclusions: Patients with LPP had a higher risk of various diseases following LPP diagnosis. Close follow-up is needed to optimize comprehensive patient care., Competing Interests: Conflicts of interest The authors declare no conflicts of interest., (© The Author(s) 2023.

- Abstract
Oral lichen planus usually occurs in adults; there are no clear data regarding the incidence and the clinical features of oral lichen planus in children. This paper reports clinical findings, treatments, and outcomes of 13 Italian patients with oral lichen planus in childhood diagnosed between 2001 and 2021. The most common finding was keratotic lesions with reticular or papular/plaque-like patterns, confined to the tongue in seven patients. Although oral lichen planus in childhood is rare and the malignant transformation index is unknown, specialists must be aware of its characteristics and oral mucosal lesions must be correctly diagnosed and managed., (© 2023 The Authors.

- Abstract
Introduction: Immune checkpoint inhibitors (ICIs) are recommended for various types of cancer. On the other hand, these ICIs may cause immune-related adverse events (irAEs). Lichen sclerosus (LS) and lichen planus (LP) are two distinct phenotypes of irAEs that occur in a subset of patients treated with ICIs. These adverse effects have a detrimental effect on the patient's quality of life and treatment phases; however, the clinical evaluation and assessment of LS and LP remain uncertain. This study aims to assess and evaluate the risk of LS and LP associated with the use of ICIs via a systematic review of the literature and the USA FDA Adverse Events FAERS database., Method: The study searched electronic databases such as PubMed, Medline, Cochrane, and Google Scholar for case reports on immune-checkpoint-inhibitor-associated lichen sclerosus and lichen planus published in English between inception and 31 December 2021. The FDA's adverse event reporting system (FAERS) database was also analyzed., Results: Thirty-eight case reports and two retrospective studies with a total of 101 patients, in addition to the FAERS data, were evaluated. More cases involved lichen planus (78.9%) than lichen sclerosis (21%). Nivolumab and pembrolizumab were most frequently reported with LS and LP, among other ICIs. Thirty-six out of thirty-eight patients with LS or LP experienced complete remission, while two patients experienced partial remission. Most of the cases had an excellent response to corticosteroids (92.1%), while the remainder had moderate (5.2%) and poor (2.6%) responses. Additionally, the reporting odds ratio (ROR) of the FAERS database indicated a favorable association for ICIs, the risk of LP, and LS. A stronger association was uniquely found between nivolumab and pembrolizumab., Conclusion: There have been published case reports for these adverse events. Healthcare providers should be aware of the possibility of lichen sclerosis and lichen planus developing in patients receiving ICIs which could necessitate hospitalization or discontinuation. Regulatory agencies are advised to monitor the risks as a potential safety signal.

- Abstract
Background: Lichen planus (LP) is a relatively frequent mucocutaneous inflammatory disease affecting the skin, skin appendages and mucosae, including oral mucosae, and less frequently the anogenital area, conjunctivae, oesophagus or larynx., Objectives: To estimate the association of LP, with emphasis on dermatological and gastrointestinal conditions, in two large independent population cohorts., Materials and Methods: We performed a phenome-wide association study (PheWAS) and examined conditions associated with LP in two unrelated cohorts, i.e. the multicentre, community-based UK Biobank (UKB: 501 381 controls; 1130 LP subjects) and the healthcare-associated Penn Medicine BioBank (PMBB; 42 702 controls; 764 LP subjects). The data were analysed in 2021. The 'PheWAS' R package was used to perform the PheWAS analyses and Bonferroni correction was used to adjust for multiple testing. Odds ratios (ORs) were adjusted for age, sex and body mass index., Results: In the UKB, PheWAS revealed 133 phenome codes (PheCodes) significantly associated with LP and most of them were confirmed in PMBB. Dermatological and digestive PheCodes were the most abundant: 29 and 34 of these disorders, respectively, were significantly overrepresented in LP individuals from both cohorts. The 29 dermatological and 12 oral disorders were often highly enriched, whereas hepatic, gastric, oesophageal and intestinal PheCodes displayed ORs in the range of 1·6-4·5. Several autoimmune disorders also exhibited OR > 5 in both cohorts., Conclusions: PheWAS in two large unrelated cohorts identified previously unknown comorbidities and may support clinical counselling of patients with LP. What is already known about this topic? Lichen planus (LP) is known to affect the skin, skin appendages and mucosae, including oral mucosae, and less frequently the anogenital area, conjunctivae, oesophagus or larynx. What does this study add? Our data provide the most comprehensive collection of associated dermatological, digestive and autoimmune disorders to date. Our findings are expected to be useful for the evaluation and management of patients with LP., (© 2022 The Authors.

- Abstract
Background and Objectives: Lichen planus (LP) is a chronic inflammatory skin disease and is a major burden for affected patients. However, data on this condition are scarce. This study aims to expand the knowledge on the epidemiology and treatment patterns of LP using German health claims data., Patients and Methods: This retrospective observational study was based on the InGef research database. Prevalent and incident LP patients were identified in the years 2015 and 2018. Descriptive statistics were calculated for demographic characteristics, treatment patterns, and comorbidity., Results: The prevalence of LP was 95.9 and the incidence was 20.1 per 100,000 individuals in 2018, corresponding to 79,605 prevalent LP cases in Germany. The first LP diagnosis was generally documented by a dermatologist or a primary care physician. Three-quarters of the incident and half of the prevalent patients received topical therapy, mostly without further systemic therapy. Comorbidity in LP patients was consistent with previously known associations., Conclusions: Available treatment options remain limited, underscoring the unmet need for safe and efficacious systemic treatment modalities. Lichen planus is frequently accompanied by clinically relevant systemic comorbidity. Taken together, these observations may improve our understanding of the burden of this disease and increase diagnostic awareness among clinicians., (© 2022 The Authors.

- Abstract
Diabetes mellitus (DM) was found to be more common in hepatitis C virus (HCV)-related cirrhotic males. However, the association between DM, or other extrahepatic manifestations (EHMs), and liver cirrhosis is still undetermined. We used a large-scale long-term study to analyze the cirrhosis risk of treatment-naïve HCV patients with EHMs as compared to those without. In this retrospective nested case-control study, we identified 11 872 treatment-naïve patients with chronic HCV between 2001 and 2013 from Taiwan National Health Insurance Research Database and divided them into patients with (cases) and without cirrhosis (controls). All patients were followed up from the index month (exact month of diagnosis) to the end of 2013, death, or study outcome, whichever occurred first. The cases and controls were 1:6 propensity score matched for age, sex, and exact month of diagnosis; finally, 8078 patients (1154 with and 6924 without cirrhosis) were included in the analysis. The presence of coexisting EHMs and a new diagnosis of cirrhosis was analyzed. Adjusted hazard ratios (HRs) and cumulative incidence for cirrhosis were calculated in conditional Cox regression models after propensity score matching. Patients with high-cirrhosis-risk EHMs, such as DM (HR: 1.72, 95% CI: 1.51-1.96, P < .001), HCD (HR: 1.45, 95% CI: 1.27-1.67, P < .007), CKD (HR: 1.21, 95% CI: 1.05-1.38, P < .001), hyperlipidemia (HR: 0.53, 95% CI: 0.46-0.60, P < .001), lichen planus (HR: 2.71, 95% CI: 1.56-4.72, P < .001), and palpable purpura (HR: 2.67, 95% CI: 2.13-3.35, P < .001) exhibited significantly higher risk of liver cirrhosis than those without. Cumulative incidence (P < .001) of liver cirrhosis by pairwise comparisons of multiple high-cirrhosis-risk EHMs, and that of lichen planus was the highest. Our study provided direct estimates of specific HCV-associated EHM time trends of cirrhosis risk, with an upward trend in incidence. Lichen planus was at the top of the list of single-EHM comparisons, and the maximum combination of certain EHMs was the greatest risk factor across a different array of multi-EHM comparisons for liver cirrhosis development., (Copyright © 2022 the Author(s).

- Abstract
Objective: Vulvar lichen sclerosus (VLS) and possibly vulvar lichen planus (VLP) are associated with an increased vulvar cancer (VC) risk. We analyzed the risk of VC and its precursors after a diagnosis of VLS or VLP., Materials and Methods: A search was performed to identify articles describing the development of vulvar neoplasia in women with VLS or VLP. This systematic review was registered with the PROSPERO database., Results: Fourteen studies on VLS included 14,030 women without a history of vulvar neoplasia. Vulvar cancer, differentiated vulvar intraepithelial neoplasia (dVIN), and vulvar high-grade squamous intraepithelial lesion occurred in 2.2% (314/14,030), 1.2% (50/4,175), and 0.4% (2/460), respectively. Considering women with previous or current VC, the rate was 4.0% (580/14,372). In one study, dVIN preceded VC in 52.0% of the cases. Progression of dVIN to VC was 18.1% (2/11).The risk was significantly higher in the first 1-3 years after a biopsy of VLS and with advancing age; it significantly decreased with ultrapotent topical steroid use.For the 14,268 women with VLP (8 studies), the rates of VC, dVIN, and vulvar high-grade squamous intraepithelial lesion were 0.3% (38/14,268), 2.5% (17/689), and 1.4% (10/711), respectively., Conclusions: Vulvar lichen sclerosus is associated with an increased risk of VC, especially in the presence of dVIN and with advancing age. Ultrapotent topical steroids seem to reduce this risk. An increased risk of developing VC has been suggested for VLP. Hence, treatment and regular life-long follow-up should be offered to women with VLS or VLP., Competing Interests: The authors have declared they have no conflicts of interest., (Copyright © 2022, ASCCP.)

Background: This study aims to determine the risk of developing anxiety and/or depression among patients with lichen planus., Methods: Based on the Longitudinal Health Insurance Database of Taiwan National Health Insurance Research Database, a total of 4012 patients with lichen planus and 16,048 matched controls (1:4) were enrolled between January 1, 2000, and December 31, 2015. After controlling for the risk variables, multivariate Cox proportional hazard regression and the log-rank test with Kaplan-Meier method were performed to assess the influence of anxiety/depression among individuals with lichen planus under a maximum follow-up period of 16 years., Results: The subsequent anxiety or depression incidence of the lichen planus group and the comparisons was 19.67% (1962.70 per 10
5 person-years) and 10.11% (982.23 per 105 person-years), respectively. Additionally, after adjustment of the risk variables, the hazard ratios for anxiety, depression, anxiety without depression, depression without anxiety, anxiety or depression, and both anxiety and depression combined were 1.779 (95%CI: 1.289-2.477, p < 0.001), 2.010 (95%CI: 1.454-2.790, p < 0.001), 2.015 (95%CI: 1.463-2.799, p < 0.001), 2.356 (95%CI: 1.705-3.286, p < 0.001), 2.011 (95%CI: 1.457-2.793, p < 0.001), and 1.515 (95%CI: 1.100-2.134, p < 0.001), respectively., Limitations: Individuals with lichen planus were unable to be classified into oral subtype and cutaneous subtype based on the ICD-9-CM. Moreover, the results of our study could not demonstrate the mechanism between lichen planus and anxiety and/or depression., Conclusion: Patients with lichen planus was positively associated with developing anxiety or depression. Physicians should to be aware of the signs of anxiety and/or depression while facing the patients with lichen planus during the clinical practices., (Copyright © 2021 Elsevier B.V.

- Abstract
Background: Unlike other types of lichen planus (LP), there are no series concerning male genital LP., Objective: To describe the clinical characteristics, diagnosis, and response to treatment of male genital LP., Patients and Methods: A retrospective study of male patients with genital LP consulting a dermatologist specialized in anogenital diseases between January 2010 and 2019. Demographic data, history, functional signs, clinical characteristics, pathology, complications, and treatment efficacy were collected., Results: Eighty-nine patients were included at four centers. The median age was 51 years. Most patients were uncircumcised and asymptomatic. In 88.8% of cases, only the genital mucosa was involved. Erythema (71%), papules (21.3%), lacy network (15.7%), atrophic lesions (15.7%), erosions (14.6%), and post-inflammatory hyperpigmentation (2.2%) were less frequently observed. Biopsy results confirmed LP in 61.3% of cases but could not rule out other inflammatory genital dermatoses in other cases. Anatomic complications were observed in 30.3% of patients. Topical corticosteroids (TCS) induced remission in most cases. Tacrolimus efficacy was comparable to that of TCS., Conclusion: Male genital LP is a rare inflammatory disorder chiefly affecting uncircumcised men. It is found predominantly on the mucosal component of the penis and presents as non-erosive inflammatory balanitis in most cases, with frequent partial or complete remission on treatment with TCS., (Copyright © 2021 Elsevier Masson SAS.

- Abstract
Objectives: The objectives of this study were to determine: 1) the prevalence of lichen sclerosus (LS) and lichen planus (LP) present in association with vulvar squamous cell carcinoma (VSCC), and 2) the incidence and absolute risk of developing VSCC in LS and LP., Methods: A search was performed of MEDLINE, EMBASE and CINAHL databases. Three independent reviewers screened articles published before September 1, 2020, first on title/abstract and then on the full text. Women with a history of VSCC, human papillomavirus, smoking, or autoimmune disease were excluded. Newcastle-Ottawa observational study scales were used to assess the risk of bias and methodological quality of the included studies. Of the 3132 studies assessed, 31 were selected for analysis. Due to study heterogeneity, a qualitative synthesis was conducted., Results: The prevalence of LS and LP in association with VSCC ranged from 0% (95% CI 0-5) to 83% (95% CI 36-100) and 1% (95% CI 0-7) to 33% (95% CI 4-78), respectively. The incidence of VSCC ranged from 1.16 (95% CI 0.03-6.44) to 13.67 (95% CI 5.50-28.17) per 1000 person-years for LS. The absolute risk of developing VSCC in patients ranged from 0.0% (95% CI 0.0-5.52) to 21.88% (95% CI 9.28-39.97) with LS and was 1.16% (95% CI 0.1-4.1) with LP. Incidence was not calculable for LP owing to study characteristics., Conclusions: This review provides evidence that there is an increased risk of developing VSCC in women with LS, while associations with LP are less clear. Early identification, treatment, and long-term follow-up are essential to prevent potential malignant progression of these vulvar dermatoses., (Copyright © 2021. Published by Elsevier Inc.)

- Abstract
Background: Lichen planus (LP) is a chronic inflammatory dermatosis, involving the skin, appendages, and mucous membranes. There is a growing body of evidence about higher risk of metabolic syndrome and dyslipidemia in some dermatoses including LP., Aim: To evaluate lipid profile, leptin, and CRP status among Iranian LP patients, compared to healthy controls, and peruse the relationship between abnormal values of these parameters with the disease duration and physical characteristics of patients., Methods: 40 LP patients and 40 age- and sex-matched healthy controls were enrolled in the study. Data on weight, height, lipid profile, leptin, and CRP values were recorded and compared., Results: The mean values for leptin, CRP, and lipid profile parameters (except for HDL) were higher in patients, compared to controls. Total cholesterol level was negatively associated with disease duration in patients ( P value: 0.039, r: -0.33). Serum leptin level was positively correlated with BMI both in patients and controls ( P value: 0.037 and 0.003, respectively). In the patient group, LDL level, although insignificant, was higher in men, but HDL and leptin levels were significantly higher in women in comparison with men ( P value: 0.018)., Conclusion: Screening of LP patients in regard to their lipid profile might be more reasonable in men or those who have other cardiovascular risk factors to prevent morbidity and mortality in result of developing cardiovascular events., Competing Interests: The authors declare no conflicts of interest regarding the publication of this article., (Copyright © 2022 Zeinab Aryanian et al.)

- Abstract
Fibrosing alopecia in a pattern distribution (FAPD) is a unique entity which presents clinicopathological characteristics of both male/female pattern androgenetic alopecia (AGA) and lichen planopilaris (LPP). This entity was first reported in 2000 and its criteria was recently proposed. Etiopathogenesis of FAPD has been speculated to be immunological destruction involving miniaturized hair follicles but still remains elusive. To date, few Asian FAPD cases have been reported in the literature. In this study, Japanese FAPD cases were identified based on the aforementioned criteria and analyzed to delineate clinicopathological characteristics. By retrospectively revisiting medical records and clinical photographs, 24 Japanese cases comprising 17 women and seven men were diagnosed as FAPD. All male patients had disease onset by their early 30s, whereas most female patients had developed the condition in middle age or later. Their initial diagnoses prior to the diagnostic confirmation of FAPD were mostly LPP. Based on the clinical phenotypes, the cases were categorized into AGA and LPP types. These subtypes were characterized by foremost trichoscopic and histopathological findings of AGA or LPP, respectively. Unlike previously reported cases, our patients tended to manifest hair loss in both vertex and frontal to mid-scalp with minimal regression of anterior hairline, manifesting unique "parachute" pattern, which has been reported as a representative characteristic of East Asian AGA in the literature. Anti-inflammatory therapies seemed to be effective to deter hair loss but insufficient to achieve improvement. Further accumulation of the cases is necessary; however, these findings may provide additional pathophysiological insights into FAPD and highlight uniqueness of the etiology and clinical phenotype of Japanese FAPD putatively influenced by racial predispositions., (© 2021 Japanese Dermatological Association.)

- Abstract
The disease burden of lichen planus and its impact on patients' quality of life have not been well studied. The aim of this mono-centre cross-sectional study was to investigate these factors. From June to September 2020, an anonymous survey was posted to 253 patients, who were diagnosed with lichen planus in our outpatient clinic from January 2018 to June 2020. Quality of life was evaluated using the Dermatology Life Quality Index (DLQI), the EuroQol 5-dimension 3-level score, and further quality of life indicators. Beck Depression Inventory II was used to evaluate symptoms of depression. A total of 100 patients completed and returned the survey. Lichen planus affected quality of life in 78% of cases. DLQI was higher for multiple localizations (r = 0.454, p < 0.001). Patients with genital lichen planus had a significantly higher DLQI (mean ± standard deviation (SD) 8.68 ± 6.96) than patients who were not affected in the genital area (5.01 ± 5.49; p = 0.009). DLQI was also significantly higher for ungual lichen planus (9.83 ± 7.6; not affected: 5.65 ± 5.84; p-value 0.039), and for cutaneous LP (mean 8.1, SD 6.22; not affected: 5.63 ± 6.12; p-value 0.045). Twenty-nine percent of patients had mild to moderate symptoms of depression, and 6% had severe symptoms of depression. Depression and reduced quality of life are an undetected and relevant burden affecting patients with lichen planus.

- Abstract
Background/objectives: Fibrosing alopecia in a pattern distribution (FAPD) is a newly recognized form of scarring alopecia sharing characteristics of both androgenetic alopecia (AGA) and lichen planopilaris. The existing literature on FAPD and current understanding of the epidemiology, pathogenesis, clinical features, diagnosis, and treatment of this disease are reviewed., Methods: PubMed searches were performed to identify all articles discussing FAPD. The references of articles were used to identify additional articles., Results: A total of 15 articles were found describing FAPD in a total of 188 patients (164 women and 24 men; average age, 53.8)., Conclusions: FAPD affects the androgen-dependent scalp and is typically associated with hair follicle miniaturization. The scalp affected by FAPD shows features of both lichen planopilaris and AGA, and FAPD may possibly represent an exaggerated inflammatory response to damaged hair follicles, triggered by AGA. Physical examination and trichoscopic evidence of follicular inflammation and, occasionally, fibrosis are important to identify the condition, and a dermoscopy-guided biopsy can confirm the diagnosis. Unless recognized, clinicians may misdiagnose FAPD as AGA associated with seborrheic dermatitis. Data on treatment modalities are limited; however, based on pathogenesis, combined therapy with anti-inflammatory and hair growth-promoting agents is warranted., (Copyright © 2020 American Academy of Dermatology, Inc.

- Abstract
Vulval lichen planus (VLP) is a rare, but often chronic, inflammatory disease whose symptoms include genital pain, discomfort, and dyspareunia. The clinical manifestations include erythema, erosions, and scarring. The aim of this study was to longitudinally investigate patient-reported outcomes and clinical findings in patients with VLP. Patients (>18 years) with histologically confirmed VLP were included in the retrospective analysis. Patient demographics, clinical features, symptomatology, quality of life, management, clinical outcomes, and comorbidities associated with VLP were analyzed. Twenty-four patients were identified with a mean (standard deviation [SD]) follow-up time of 19.3 (13.8) months. Classical VLP with glazed erythema was found in seven (29.2%) patients, erosive VLP was present in 15 (62.5%) patients, and hypertrophic VLP in two (8.3%). Seven patients had additional cutaneous involvement, while six patients had both vulval and oral mucosal involvement. The labia minora was the most frequently affected anatomical site (83.3%), followed by the clitoris (58.3%). Scarring lesions were found in 62.5% (n = 15) of patients. All study participants received treatment with potent and/or superpotent topical corticosteroids but 50% required systemic therapy (acitretin, corticosteroids, or hydroxychloroquine). Five (20.8%) patients underwent surgery due to adhesions and scarring resulting from VLP. One patient was diagnosed with a vulval squamous cell carcinoma during long-term follow-up. The mean (SD) Dermatology Life Quality Index score was 8.4 (5.5) at presentation and 8.9 (6.8) at the end of follow-up. In conclusion, VLP was associated with moderate quality of life impairments which persisted despite treatment, suggesting that current treatments for VLP are inadequate., (© 2021 The Authors.

- Abstract
Aim: In the literature, there are no data examining the association with lichen planus with acanthosis nigricans and acrochordon, which are skin findings of metabolic syndrome (MS)., Materials: A total of 108 lichen planus (LP) patients, age and sex-matched 109 controls, 217 patients in total were prospectively included in the study., Results: Metabolic Syndrome was found in 55 (50.9%) of 108 patients with lichen planus and 36.7% in the control group. The frequency of MS in the lichen planus group was found to be significantly higher than that in the control group (P = .03). The incidence of acanthosis nigricans (AN) was statistically higher in the LP group (P = .009). In addition, while 38 of 47 AN patients in the LP group had MS, 17 of 61 patients without AN had MS, and the presence of MS was found significantly higher in LP patients with AN (p˂0.001). The incidence of acrochordon was statistically higher in the LP group (P = .03). In addition, while 43 of 62 patients with acrochordon in the LP group had MS, 12 of 46 patients without acrochordon had MS, and the presence of MS was found significantly higher in patients with LP with acrochordon (P ˂ .001)., Conclusion: In our study, it was found that skin findings such as AN and acrochordon increased in patients with lichen planus. This increase was also observed in lichen planus patients with metabolic syndrome. Therefore, the association of acanthosis nigricans and acrochordon may be a predictive of metabolic syndrome in patients with lichen planus admitted to the dermatology outpatient clinic., (© 2021 John Wiley & Sons Ltd.)

- Abstract
Lichen planopilaris (LPP) and frontal fibrosing alopecia (FFA) are scarring alopecias that cause significant distress and psychological morbidity. Limited studies have been performed examining the epidemiology of FFA and LPP. We performed a retrospective case cohort analysis by querying for patients with the ICD 10 code L66.1 (LPP, FFA) between 2015 and 2018 using the Clinical Data Warehouse (CDW) at NewYork-Presbyterian Hospital and Columbia Doctors. We calculated the one-year incidence of LPP/FFA between January 1, 2018 to December 31, 2018 by identifying all patients without a previously recorded ICD code for L66.1 who presented as a new hair loss patient based on chart review. A total of 170 patients were identified with a new diagnosis of LPP or FFA in 2018 among 1,187,583 patients. The standardized incidence per 100,000 was 12.75 for LPP and FFA combined, 7.35 for LPP alone, and 5.41 for FFA alone. The incidence peaked in the 51 to 60 age range (3.36). The incidence was highest in non-Hispanic White patients (17.27), White patients of unknown ethnicity (26.26), and non-Hispanic Asian patients (17.27). In New York City, LPP and FFA are uncommon diseases that are most common in middle-aged females and non-Hispanic White patients.

- Abstract
Objective: Lichen planus (LP) is an idiopathic, chronic inflammatory disease. Chronic inflammatory diseases can cause metabolic complications. In the literature, data related to the relationship between lichen planus and metabolic syndrome (MS) are limited. We aimed to evaluate the relationship between MS and lichen planus with disease activity., Methods: The patients diagnosed with lichen planus at the dermatology outpatient clinic between January 2018 and January 2020 were retrospectively analyzed. 98 lichen planus cases, age- and sex-matched 99 controls, 197 cases in total were included in the study., Results: Of the 98 lichen planus cases included in the study, 60 (61%) were women. The mean age of the patients was 49.3 ± 14.4, and the average disease duration was 33.5 ± 31.4 months. 55 (55%) of the patients in the control group were female, and the mean age of the control group was 50 ± 13.2. The body mass index of LP cases was 29.5 ± 5.8, in the control group was 25.8 ± 3.7. Metabolic syndrome was found in 47 (48%) of 98 cases with lichen planus and 32.3% in the control group. MS in the lichen planus group was significantly higher than the control group (P = .025). Metabolic syndrome was detected in the oral lichen planus at the rate of 60% (12 cases). Although the incidence of MS was more common in the oral lichen planus, it was not statistically significant (P = .29). While no significant relationship was found between oral disease severity and metabolic syndrome (P = .19), a significant correlation was found between cutaneous disease severity and metabolic syndrome (P = .023)., Discussion: The risk of mucosal malignancy that can occur when following LP cases has been known for a long time. According to our results, caution should be taken in terms of metabolic complications in the follow-up of LP cases, especially oral LP cases., (© 2020 Wiley Periodicals LLC.)

- Abstract
An involvement of the esophagus in patients with lichen planus was described for the first time in 1982. Ever since, it has been seen as a rarity. However, studies over the last 10 years have shown a higher prevalence than expected. It may even be supposed that esophageal lichen planus (ELP) is more common than eosinophilic esophagitis. ELP mostly affects middle-aged women. The principal symptom is dysphagia. Endoscopically, ELP is characterized by denudation and tearing of the mucosa, trachealization and hyperkeratosis and esophageal stenosis may occur in patients with long courses of the disease. Histologic findings including mucosal detachment, T-lymphocytic infiltrate, intraepithelial apoptosis (civatte bodies) and dyskeratosis are crucial. Direct immunofluorescence shows fibrinogen deposits along the basement membrane zone. So far, there is no well-established therapy but a treatment with topic steroids is effective in 2/3 of the patients. Common therapy of lichen planus of the skin seems to be ineffective for treatment of ELP. Symptomatic esophageal stenosis should be endoscopically dilated. ELP joins the group of "new" immunologic diseases of the esophagus., Competing Interests: Die Autorinnen/Autoren geben an, dass kein Interessenkonflikt besteht., (Thieme. All rights reserved.)

- Abstract
Lichen planus (LP) is a chronic inflammatory disorder that especially affects the skin, mucous membranes, or both. The aim of the study was to determine the clinical characteristics of patients with LP in the oral cavity and concomitant cutaneous lesions and compare their outcomes with those without cutaneous lesions. 253 records of patients with confirmed diagnosis of oral lichen planus (OLP) were retrospectively analyzed. The following clinical data were obtained from the medical charts: sex, age, clinical presentations of OLP, distributions of the lesions, presence of symptoms, extra oral manifestations of lichen planus, presence of systemic diseases, and treatment provided. The group of patients with cutaneous manifestations was compared for possible clinical differences to those without. Cutaneous lesions were present in 18.2% (46/253) of patients. Significantly more patients with cutaneous lesions had other extra oral manifestations (26.1% versus 1.0%, P<0.00001). Lips were significantly more affected in patients with cutaneous presentation (41.3% versus 16.9%, P=0.00006). Ulcerative OLP was more frequent in patients with cutaneous lesions (23.9% versus 10.6%, P=0.0266). Patients with cutaneous manifestations needed significantly more systemic treatment with systemic steroids (10.9% versus 3.4%, P=0.0466). Patients with cutaneous lesions were more symptomatic and tended to require more treatment than patients with OLP who only had oral involvemen.

- Abstract
Nail lichen planus is an inflammatory disorder of the nails with potential for significant cosmetic disfigurement and functional impairment. Nail manifestations may be isolated or appear concurrently with other forms of lichen planus. Longitudinal ridging is the most common clinical finding, but progressive disease may result in irreversible scarring (dorsal pterygium) or permanent nail loss (anonychia). Data on treatment are limited to retrospective studies and case reports. The mainstays of treatment are intralesional and intramuscular corticosteroid injections and oral retinoids. There is a need for randomized controlled trials on nail lichen planus to more rigorously assess efficacy and outcomes., Competing Interests: Disclosure M.K. Gupta and Dr S.R. Lipner have no conflicts of interest relevant to the content of the submission., (Copyright © 2020 Elsevier Inc. All rights reserved.)

- Abstract
Background: Lichen planopilaris (LPP) is a scarring alopecia rarely described in men., Objective: To investigate the clinical and histopathologic features of LPP in men., Methods: We performed a retrospective cohort study of male patients with LPP seen at Mayo Clinic between 1992 and 2016., Results: Nineteen men with biopsy-confirmed LPP were included. The disease most commonly presented with diffuse (42.1%) or vertex scalp (42.1%) involvement. None of the patients had eyebrow or body hair involvement. Perifollicular erythema (94.7%) and pruritus (57.9%) were the most frequent clinical findings. Androgenetic alopecia (AGA) co-occurred in 26.3% of patients. Mucosal lichen planus was found in four patients (21.1%). Thyroid disease occurred in three patients (15.8%). Disease improvement (47.3%) occurred with combination topical and systemic therapy, topical clobetasol monotherapy, and minocycline monotherapy., Conclusions: LPP in men has similar clinical and histologic presentations as reported in women. Nonscalp hair loss appears less likely in men with classic LPP than reported in men with frontal fibrosing alopecia, while mucosal lichen planus and thyroid disease appear to be more common in classic LPP. Men with AGA can present with new-onset concomitant LPP. Limitations included small study size, variable follow-up, and lack of standardized clinical assessment due the study's retrospective nature., (© 2020 the International Society of Dermatology.)

- Abstract
Frontal fibrosing alopecia (FFA) is a patterned primary cicatricial alopecia that was first described in 1994. Once rare, the incidence of FFA has increased dramatically, representing the current most common cause of cicatricial alopecia worldwide. FFA typically begins in postmenopausal women with symmetrical, progressive recession of the frontotemporal hairline together with bilateral loss of the eyebrows. FFA has a distinctive clinical phenotype, which remains a challenge. The histology is identical to lichen planopilaris (LPP), but only a small number of patients have coincidental LPP, usually of the scalp. The vast majority of patients have no evidence of lichen planus elsewhere, and the symmetry and patterned nature of the hair loss are unusual for LPP. Familial cases of FFA are reported, and gene associations have been identified in population studies; however, the pathophysiology remains controversial. Without treatment, FFA is slowly progressive, and although many treatments have been prescribed, the response is often disappointing. We review the pathogenesis, epidemiology, clinical features, histology, and treatment of FFA., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2020 Elsevier Inc.

- Abstract
Background: Despite the incidence of Frontal fibrosing alopecia (FFA) has been increasing in last two decades, the pathophysiology and trigger factors of FFA have not been yet fully understood., Aims: The aim of this study was to describe epidemiology, clinical and trichoscopic features and comorbidities of FFA patients, in order to improve the understanding of this disease., Patients/methods: A retrospective, observational monocentric study was conducted from 2003 to 2019. Data concerning epidemiology (age, gender, age of menopause, and age of FFA onset), comorbidities, current therapies, localization of FFA (such as frontotemporal hairline, occipital, eyebrow, eyelash, beard, sideburns, and body hair), presence of papules and sign of Lichen planus (LP) at skin, mucosae and/or nail were collected for each patient included., Results: A total of 119 Caucasian, adult patients (8 men and 111 female) with FFA were enrolled in the study. Cutaneous, mucosal, or nail localization of LP were found in 16% of our subjects. Interestingly, 15 out of 119 subjects (10.61%) were affected by concomitant genital Lichen sclerosus (LS) and 5 out of these 15 patients (4.38%) presented both LS and LP in association with FFA., Conclusion: Considering the high prevalence of LS in FFA patients in our case series, and the frequency of autoimmune comorbidities in both LS and FFA, it is possible to hypothesize an autoimmune process in both conditions. Further studies are needed for a better understanding of the nature of the association between LS and FFA., (© 2020 Wiley Periodicals, LLC.)

- Abstract
Objective: The aim of the study was to assess the risk of vulvar cancer and precursors in a cohort of women with vulvar lichen planus (LP) and the clinical and therapeutic features of these patients., Materials and Methods: A retrospective cohort study, including all the women with the diagnosis of vulvar LP, followed in one institution during a period of 11 years, was performed. Demographic and clinical data, as well as treatment, follow-up, and histology results, were evaluated., Results: A total of 127 women were diagnosed with vulvar LP. The mean follow-up time was 3.9 ± 0.5 years (range = 1-11 years). Ultrapotent topical corticosteroids were first-line treatment in 91.8% (n = 112), with 32 cases (25.2%) needing an alternative treatment. Overall, 30 biopsies were performed in 19 women (15%). Vulvar high-grade squamous intraepithelial lesion was diagnosed in 3 women (2.4%), 2 (1.6%) of whom were later diagnosed with vulvar squamous cell carcinoma. No cases of differentiated vulvar intraepithelial neoplasia were observed., Conclusions: Premalignant/malignant transformation in women with vulvar LP under surveillance and compliant with treatment is low. A close follow-up seems to be crucial to prevent future malignancy. Biopsies should be performed whenever a suspicious lesion seems during follow-up., Competing Interests: The authors have declared they have no conflicts of interest., (Copyright © 2020, ASCCP.)

- Abstract
The association between certain chronic inflammatory skin diseases and psychiatric disorders or conditions has been well documented. However, the exact magnitude of the association between lichen planus and depression/anxiety symptoms and disorders is un-known. A systematic review and pooled meta-analyses were performed to examine the prevalence and odds of depression and anxiety in patients with lichen planus. The meta-analyses showed a high prevalence of signs of depression (27% [19-36%]) and anxiety (28% [21-36%]). The geographical location of the study may partly explain these vari-ations, but method-ological differences could also be involved. Case-control studies showed a strong association between lichen planus and signs of depression (odds ratio 3.79, 95% confidence interval [2.35; 6.12]) or anxiety (odds ratio 2.54, 95% confidence interval [1.73; 3.72]). These results raise the necessity of screening for the presence of depressive and anxiety symptoms or disorders in patients with lichen planus, and of referring such patients for psychiatric evaluation and appropriate treatment, if necessary.
