Vulvar lichen sclerosus : pathophysiology and treatment

Perineural Inflammation as a Novel Feature in Lichen Sclerosus: A Case Series of Histologic and Clinical Features

ABSTRACT

Lichen sclerosus (LS) is a frequently encountered inflammatory skin disorder characterized by whitened, atrophic patches that can cause pain and pruritus. The underlying cause of this condition remains unknown. Primarily affecting the genital area, this condition carries an increased risk of developing cutaneous cancers and frequently co-occurs with autoimmune disorders. Our retrospective study aimed to explore histologic features of LS, with a particular focus on a newly established finding and its potential implications. We examined 53 histologic cases of LS collected over 2 years. Experienced pathologists evaluated and reached a consensus on the assignment of histologic features. Patient charts were manually reviewed to gather relevant demographic and clinical data. Statistical analysis was performed using IBM SPSS Statistics (2021). Of the 53 total patients identified as meeting criteria for inclusion in this study, only 8 (15%) were male. Eight cases (15%) demonstrated perineural inflammatory infiltrate. Notably, half of all samples from male patients exhibited perineural inflammatory infiltrate. A statistically significant increase ( P < 0.01) in the presence of dermal plasma cells was identified in cases with perineural inflammation versus cases without this feature. The findings of our study highlight the recurrent nature of perineural inflammation in LS, providing valuable insights into this condition. Furthermore, we observed a notable correlation between perineural inflammation, male patients, and the presence of dermal plasma cells. These discoveries contribute to a better understanding of the underlying mechanisms of LS and suggest avenues for future research into the condition.

Cutaneous Mimics of Child Abuse & Neglect: Part II

Given that some cutaneous mimics of child abuse result from rare disease, they may be more prone to misdiagnosis. For possible child abuse cases in which diagnosis remains uncertain at time of initial dermatologic evaluation, it is important that dermatologists are prepared to distinguish true dermatologic conditions in cases of ambiguous skin findings. Additionally, this review will aid clinicians in recognizing the possibility of concurrent true dermatologic disease and skin findings related to abuse with the acknowledgement that they are not mutually exclusive. Proper recognition of mimics of abuse may prevent unnecessary stress and child protective service investigation.

Lichen sclerosus of the vulva

Lichen sclerosus of the vulva (LSV) is seen frequently enough to warrant knowing how to diagnose it and institute appropriate treatment strategies. LSV is a chronic skin disorder, very likely of autoimmune origin, which may affect various areas of the perineum, although some women may be affected in extragenital areas. The disease has significant adverse impact on quality of life and sexual activity and may undergo malignant transformation. History of symptomatology and clinical examination is sufficient to make the diagnosis. Skin biopsy is only necessary in specific scenarios. Topical corticosteroids are still the mainstay of therapy, initially to institute remission and then for maintenance. Long-term therapy and surveillance are invariably necessary. Surgery does have a role, but only in specific associated conditions. A number of alternative treatment options have been mooted, especially if the disease is resistant to topical corticosteroids, but these options are still being assessed and studied.

Vulvar Pruritus: A Review of Clinical Associations, Pathophysiology and Therapeutic Management

Vulvar pruritus is an unpleasant sensation and frequent symptom associated with many dermatologic conditions, including infectious, inflammatory and neoplastic dermatoses affecting the female genitalia. It can lead to serious impairment of quality of life, impacting sexual function, relationships, sleep and self-esteem. In this review, common conditions associated with vulvar itch are discussed including atopic and contact dermatitis, lichen sclerosus, psoriasis and infectious vulvovaginitis. We review the potential physiologic, environmental and infectious factors that contribute to the development of vulvar itch and emphasize the importance of addressing their complex interplay when managing this disruptive and challenging symptom.

The short-term efficacy and safety of fractional CO2 laser therapy for vulvovaginal symptoms in menopause, breast cancer, and lichen sclerosus

OBJECTIVE

To review the short-term effects and safety of vulvovaginal fractional microablative CO2 laser therapy on atrophy symptoms using validated questionnaires pre- and posttreatment.

METHODS

This is a retrospective chart review from January, 2016 to December, 2019 on 139 women with vulvovaginal atrophy symptoms, who completed three treatments about 6 weeks apart. All were >18 years old and nonpregnant. As is the practice in our clinic for all women receiving treatment, they were surveyed prior to the 1st and 3rd treatments with validated questionnaires, Female Sexual Function Index (FSFI) and Vulvovaginal Symptoms Questionnaire (VSQ), as well as a visual analog scale (VAS). Paired t test was completed on the pre- and post FSFI and VAS scores. Pre- and postproportions of the VSQ were evaluated by the Fisher's exact test. Means were presented for each study variable. Multivariable regression analysis was completed on continuous and binomial variables for scores predictors.

RESULTS

Mean age was 62 years with a mean follow-up of 13.8 weeks. Concomitant topical estrogen was reported in 53% (n = 74). Breast cancer diagnosis was documented in 27% (n = 38), and lichen sclerosus in 22% (n = 31). All FSFI scores improved (pre: 12.7, post: 19.0, P < 0.001). The VSQ showed 18 of 21 questions significantly improved (P < 0.05). The VAS showed significant improvement in painful intercourse (pre: 6.6, post: 2.4, P < 0.001), and vulvar dryness (pre: 4.6, post: 1.5, P < 0.001). Posttreatments, 17 additional women became sexually active. No major adverse events were reported.

CONCLUSIONS

Fractional CO2 laser may be effective and safe for the treatment vulvovaginal atrophy.

Outcome of perineoplasty and de-adhesion in patients with vulvar Lichen sclerosus and sexual disorders

OBJECTIVE

Vulvar Lichen sclerosus (LS) is a chronic inflammatory disease in which architectural changes and symptoms like itching, soreness, pain and dyspareunia can affect quality of life and sexual activity. Perineoplasty has been shown to be effective as a supportive surgical treatment in women with refractory dyspareunia in addition to the standard topical immunosuppressive treatment. The aim of this study was to evaluate retrospectively general complaints, patient satisfaction concerning sexual activity, reduction of dyspareunia/apareunia, orgasm ability and recurrence of LS after perineoplasty.

STUDY DESIGN

This study is a retrospective monocentric observational study, in which patients with vulvar LS who had undergone perineoplasty were invited to fill out a standardized questionnaire during the follow-up time. The main outcome measure is the overall patient satisfaction after surgical therapy of vulvar LS.

RESULTS

Forty-one of the 70 invited patients with a median age at surgery of 58 years (18-74 years) and a median 60 years (19-76 years) at the last follow-up were evaluated. The median follow-up time was 2.3 years (1-5 years). There was a significant (p < 0.001) reduction in general complaints after surgery. Twenty-two patients were very satisfied, 15 were satisfied and 3 were not satisfied with the outcome of the surgery. Only 2 patients would not recommend the surgery. Although, there was a significant (p = 0.02) reduction in dyspareunia after surgery, 10 patients still felt pain during sexual intercourse.

CONCLUSION

This is one of the largest studies reporting on long-term results of perineoplasty. It showed that perineoplasty is a safe surgical treatment option with a high satisfaction rate in patients with dyspareunia due to LS and a desire to regain sexual activity. Perineoplasty can improve sexual activity and achieve overall satisfaction in selected patients even though the recurrence rate of LS in sexually active patients remains high.

Development and Validation of a Clinical Grading Scale to Assess the Vulvar Region: The Vulvar Architecture Severity Scale

BACKGROUND

The vulva is composed of aesthetic units that can be affected differently by vulvar conditions. A reliable, comprehensive, and quick-to-use clinical scoring system is required to assess the disease extent in the vulvar area.

OBJECTIVES

The aim of this study was to develop and validate a grading scale based on the aesthetic unit principle to evaluate the extent of vulvar lichen sclerosus (VLS).

METHODS

After reviewing photographs of 100 patients affected by VLS, the authors targeted the aesthetic units most frequently affected. The disease signs were recorded and graded in 4 levels of severity (none, mild, moderate, severe) taking into account the vulvar architecture and skin involvement. To validate the scale, 14 observers were asked to apply it to photographs of 25 VLS patients on 2 different occasions. Intra- and inter-observer reliabilities were determined employing Pearson's and intraclass correlation coefficients.

RESULTS

A 6-region, 4-point grading system was designed and identified as the Vulvar Architecture Severity Scale (VASS). In all 6 areas, the Pearson's r was greater than 0.9 (mean, 0.994; 95% confidence interval [CI] = 0.992), indicating that the intra-observer reliability of the VASS was consistent over time (P < 0.001). Intraclass correlation at time 1 was 0.928 (95% CI = 0.910, 0.943) and at time 2 was 0.944 (95% CI = 0.931, 0.996), indicating a high reliability level among different observers.

CONCLUSIONS

The VASS is a reliable scale to assess the severity of VLS, and it might be considered as an outcome measure in future VLS trials.

Surgical treatment of clitoral phimosis

The clitoris has a crucial role in the feminine pleasure. Chronic inflammatory dermatosis along with post-menopausal atrophy of the vulva and obstetrical traumas can cause clitoral phimosis, thereby compromising its function. Medical treatments exist depending on the etiology, but when irreversible scarring occur, a surgical treatment can be necessary to regain its function. We present here our surgical technique that achieves excellent functional results with low morbidity and the outcome of our patients in order to improve this sexual dysfunction.

Lichenoid dermatoses involving the vulva: A clinical-pathologic correlation✰

The lichenoid tissue reaction pattern generally signifies cytotoxic damage to the epithelium. When such reaction pattern occurs on vulvar skin or mucosa, the effects can result in considerable morbidity. None of the entities discussed in this review are entirely unique to the vulva, however, some entities may classically occur at this site, while others tend to be widespread diseases that may incidentally affect vulvar skin and mucosa. Given the complex anatomy of the vulva and the bridging of a site showing both keratinizing squamous epithelium and non-keratinizing squamous mucosa, histopathologic features may display variation in presentation. Although identification of a "lichenoid reaction pattern" alone may provide insight into the disease process, understanding of clinical presentation and specific sites of involvement, along with recognition of the nuanced features of the disease entities can help establish a specific diagnosis. Accurate histopathologic diagnoses by pathologists can improve the ability for treating clinicians to implement timely and effective treatment.

Elastophagocytosis and interstitial granulomatous infiltrate are more common in extragenital vs genital lichen sclerosus

BACKGROUND

Genital and extragenital lichen sclerosus (LS) share similar histopathologic features. A recent small series documented elastophagocytosis uniquely in extragenital LS. We evaluated a larger series of LS for elastophagocytosis, elastic fiber loss, and other histopathologic features. We evaluated matrix metalloproteinase (MMP) expression to determine if these proteins play an etiologic role.

METHODS

Genital (n = 42) and extragenital (n = 41) LS biopsies were examined for histopathologic features, elastic fiber alteration (Verhoeff van Gieson staining), and MMP-2 and MMP-9 expression (immunohistochemistry).

RESULTS

Elastophagocytosis and an interstitial granulomatous pattern were significantly more common in extragenital LS than genital LS (43.9% vs 4.7% and 56.1% vs 9.5%). Extragenital LS had mild/focal elastic fiber loss (43.9%), while genital LS had moderate (61.9%) or marked (19%) loss. MMP-9 was diffusely expressed in histiocytes in both types of LS (genital 97.5%; extragenital 100%). Weak MMP-2 expression was seen in genital (58%) and extragenital (55%) LS.

CONCLUSIONS

Extragenital LS, but not genital LS, frequently exhibits elastophagocytosis and interstitial granulomatous infiltrate, and these patterns could contribute to elastic fiber destruction in extragenital LS. While MMP-2 and MMP-9 expression are common in LS, expression did not significantly differ depending on anatomic site and thus is unlikely to explain observed histopathologic differences.

An arm-based network meta-analysis on treatments for vulvar lichen sclerosus and a call for development of core outcome sets

OBJECTIVE

The purpose of the present systematic review is to evaluate the available medical treatments for vulvar lichen sclerosus, using an arm-based network meta-analysis protocol.

DATA SOURCES

We searched Medline (1966-2019), Scopus (2004-2019), Cochrane Central Register of Controlled Trials CENTRAL (1999-2019), Clinicaltrials.gov (2008-2019) databases, and Google Scholar (2004-2019) database along with the reference list of all included studies.

STUDY ELIGIBILITY CRITERIA

All observational, randomized, and single-arm studies that evaluated medical treatments for vulvar lichen sclerosus were considered eligible for inclusion in the present systematic review.

STUDY APPRAISAL

A network meta-analysis was carried out in R 3.4.3 using the pcnetmeta package, which uses a Bayesian hierarchical model (based in Markov chain Monte Carlo convergence simulation).

RESULTS

Sixteen studies were included in this present meta-analysis, which recruited 954 women with vulvar lichen sclerosus. Their quality was evaluated with the JADAD, Cochrane risk of bias, and risk of bias in nonrandomised studies of interventions-I tools. Clobetasol treatment ranked as the best treatment for disease remission after evaluating rank probabilities (40% chance of ranking first compared with tacrolimus [38%]). However, the density plot revealed partial overlapping with tacrolimus. The lowest probability of experiencing a relapse was observed with pimecrolimus (15% [2-48%]); however, the density plot revealed significant overlapping with mometasone furoate, testosterone, and clobetasol.

CONCLUSION

Robust evidence concerning the superiority of potent steroids at least over calcineurin inhibitors is still lacking in the field of vulvar lichen sclerosus. On the other hand, the gross heterogeneity in terms of selected population, duration of treatment, administered regimen, outcome reporting, and selection of outcome measures leaves several fields unanswered.

Proposition of standardized protocol for photodynamic therapy for vulvar lichen sclerosus

Background: Photodynamic therapy (PDT) is an alternative treatment modality for vulvar lichen sclerosus (VLS) which is a chronic inflammatory mucosal condition. In literature, no consensus of optimal parameters of PDT for VLS is reached so far.Objectives: The aim of this narrative review is to develop a standardized treatment protocol for PDT in VLS.Methods: A systematic literature search was conducted to identify studies reporting on PDT in VLS and used treatment parameters, side-effects, and clinical outcomes were summarized.Results: Thirteen studies used 5-aminolevulinic acid (5-ALA) with concentrations of 20%, 10%, 5% and three studies used methyl aminolevulinate (MAL). Generally, the light source was red light (median 630 nm). Light dose varied between 9 and 180 J/cm² and light intensity between 40 and 700 mW/cm². Incubation period with the photosensitizer ranged from 2 to 6 h. All studies showed a substantial improvement in VLS-related pruritus, burning and pain.Conclusions: Based on a literature review, we suggest the following protocol for PDT in VLS: 5% 5-ALA as a photosensitizer applied for 3 h under occlusion before irradiation at the dose of 120 J/cm² with red light (590-760 nm) and intensity of 204 mW/cm².

Vulvar pruritus-Causes, Diagnosis and Therapeutic Approach

BACKGROUND

In Germany, 17-23% of the population suffers from chronic itching of the skin; in 5-10% of cases, the female genitalia are affected, specifically, the vulva. Vulvar pruritus is thus a common symptom that often markedly impairs the affected women's quality of life.

METHODS

This review is based on pertinent publications that were retrieved by a selective search in MEDLINE/PubMed for articles on the pathogenesis, diagnosis, and treatment of vul- var pruritus. The search terms were (in German and English) "vulvärer Juckreiz," "pruritus vulvae," and "genital itch," alone and in combination with "Behandlung," "Therapie," or "treat- ment."

RESULTS

The most common cause of vulvar pruritus is vulvo- vaginal candidiasis followed by chronic dermatoses, such as lichen sclerosus and vulvar eczema. Especially in refractory cases, an invasive or preinvasive lesion such as squamous epithelial dysplasia (VIN, vulvar intraepithelial neoplasia) should be borne in mind in the differential diagnosis. Rarer causes include infection, atrophy, and vulvodynia. The essen- tial elements of treatment are topical/oral antimycotic drugs and high-potency glucocorticoids, along with consistently ap- plied, basic moisturizing care and the avoidance of potential triggering factors.

CONCLUSION

As vulvar pruritus has multiple causes, standard- ization of its diagnostic evaluation and treatment would be l efficacy and to meet the diverse needs of women who suffer from this condition.

Clitoral Phimosis: Effects on Female Sexual Function and Surgical Treatment Outcomes

BACKGROUND

Surgery is the optimal treatment for a severe form of clitoral phimosis (CP) that is initiated by lichen sclerosus (LS) and causes female sexual dysfunction.

AIM

We aimed to determine the etiology of clitoral phimosis, its influence on sexual function, and outcomes after surgical treatment.

METHODS

In this prospective cohort study, we observed the occurrence of clitoral phimosis and related changes in a group of 3,650 sexually active heterosexual women with a mean age of 34.8 ± 14.9 years (20-45 years) from September 2014 to September 2016. Ultimately, we compared the changes in sexual function and distress and satisfaction with postoperative genital appearance in 9 patients with severe clitoral phimosis at 12 months after surgical treatment.

MAIN OUTCOME MEASURES

Sexual function was evaluated using the Female Sexual Distress Scale-Revised and the Female Sexual Function Index, and the patient's genital self-image was evaluated using the Female Genital Self-Image Scale; gynecologic examinations were performed on all patients.

RESULTS

Various forms of CP were found in 46 of 3,650 patients (1.3%). Severe forms of CP were found in 9 cases, but it was complicated by stenosis of vaginal introitus in only 2 cases. These 9 patients underwent circumcision, and 2 of them underwent perineoplasty. Female sexual dysfunction occurred mainly in those with LS and severe forms of phimosis. Sexual function, as indicated by the total Female Sexual Function Index score, was significantly improved at 12 months after surgery (17.9 ± 0.9 vs 26.6 ± 0.5; P < .001). The Female Genital Self-Image Scale score assessing genital perception was significantly higher after surgery than before in women who underwent clitoral circumcision (20 ± 3.0 vs 12.3 ± 3.3; P < .001). The Female Sexual Distress Scale-Revised score was significantly lower after surgery than before (21.3 ± 6.2 vs 33.8 ± 6.9; P < .001). Sexual function in 2 women with CP and stenosis of vaginal introitus improved after surgery, but the sexual distress level did not decrease significantly.

CLINICAL IMPLICATIONS

The results of this study will help clinicians to centralize treatment methods and advise patients on the management of clitoral phimosis.

STRENGTHS & LIMITATIONS

This is a study evaluating postoperative results of sexual function, distress, and satisfaction with genitalia in women with severe CP, using validated questionnaires. However, the small number of patients and the absence of an appropriate control group are limitations.

CONCLUSION

Surgical treatment of clitoral phimosis can improve sexual function, but because LS-a common underlying cause-is chronic in nature, patients may experience recurrence.

Lichen Sclerosus: An autoimmunopathogenic and genomic enigma with emerging genetic and immune targets

Lichen sclerosus (LS) is an inflammatory dermatosis with a predilection for anogenital skin. Developing lesions lead to vulvar pain and sexual dysfunction, with a significant loss of structural anatomical architecture, sclerosis, and increased risk of malignancy. Onset may occur at any age in both sexes, but typically affects more females than males, presenting in a bimodal fashion among pre-pubertal children and middle-aged adults. A definitive cure remains elusive as the exact pathogenesis of LS remains unknown. A general review of LS, histologic challenges, along with amounting support for LS as an autoimmune disease with preference for a T_h1 immune response against a genetic background is summarized. In addition to the classically referenced ECM1 (extracellular matrix protein 1), a following discussion of other immune and genetic targets more recently implicated as causative or accelerant agents of disease, particularly miR-155, downstream targets of ECM1, galectin-7, p53, and epigenetic modifications to CDKN2A, are addressed from the viewpoint of their involvement in three different, but interconnected aspects of LS pathology. Collectively, these emerging targets serve not only as inherently potential therapeutic targets for treatment, but may also provide further insight into this debilitating and cryptic disease.

Skin lesions, differential diagnosis and practical approach to potential survivors of torture

As the international refugee crisis has reached new proportions (BMJ, 355, 2016 and i5412), survivors of torture increasingly present in treating physicians with an array of acute or chronic skin lesions. Physicians should be aware of common presentations and likely differential diagnoses in order to avoid mislabelling or under-recognizing torture. Survivors of torture also frequently suffer from psychological sequelae, such as post-traumatic stress disorder, and appropriate referrals are essential in order to improve recovery trajectory. Skin sequelae are the most common physical findings of torture. Not all skin lesions seen in tortured survivors are due to perpetrator inflicted injuries, and many dermatological conditions can mimic lesions typical of torture, as can scars as a result of folk remedies or cultural practices specific to geographical regions. Medical documentation of torture includes injury and lesion description. While forensic dermatology and other forensic specialties use an injury description taxonomy, and the standard dermatologic taxonomy uses an anatomic description, they are complementary sciences for lesions inflicted by torture. This results in an opportunity for learning across disciplines in order to improve evidence documentation for survivors of torture. This article describes features of common skin lesions consistent with torture, including their clinical appearances, differential diagnoses, patterns of injury and appropriate clinical descriptions.

Role of Androgens in Female Genitourinary Tissue Structure and Function: Implications in the Genitourinary Syndrome of Menopause

INTRODUCTION

Genitourinary conditions in women increase in prevalence with age. Androgens are prerequisite hormones of estrogen biosynthesis, are produced in larger amounts than estrogens in women, and decrease throughout adulthood. However, research and treatment for genitourinary complaints have traditionally focused on estrogens to the exclusion of other potential hormonal influences.

AIM

To summarize and evaluate the evidence that androgens are important for maintaining genitourinary health in women and that lack of androgenic activity can contribute to the development of symptoms of the genitourinary syndrome of menopause.

METHODS

The role of androgens in the pathophysiology, diagnosis, and treatment of genitourinary syndrome of menopause was discussed by an international and multidisciplinary panel during a consensus conference organized by the International Society for the Study of Women's Sexual Health. A subgroup further examined publications from the PubMed database, giving preference to clinical studies or to basic science studies in human tissues.

MAIN OUTCOME MEASURES

Expert opinion evaluating trophic and functional effects of androgens, their differences from estrogenic effects, and regulation of androgen and estrogen receptor expression in female genitourinary tissues.

RESULTS

Androgen receptors have been detected throughout the genitourinary system using immunohistochemical, western blot, ligand binding, and gene expression analyses. Lower circulating testosterone and estradiol concentrations and various genitourinary conditions have been associated with differential expression of androgen and estrogen receptors. Supplementation of androgen and/or estrogen in postmenopausal women (local administration) or in ovariectomized animals (systemic administration) induces tissue-specific responses that include changes in androgen and estrogen receptor expression, cell growth, mucin production, collagen turnover, increased perfusion, and neurotransmitter synthesis.

CONCLUSION

Androgens contribute to the maintenance of genitourinary tissue structure and function. The effects of androgens can be distinct from those of estrogens or can complement estrogenic action. Androgen-mediated processes might be involved in the full or partial resolution of genitourinary syndrome of menopause symptoms in women. Traish AM, Vignozzi L, Simon JA, et al. Role of Androgens in Female Genitourinary Tissue Structure and Function: Implications in the Genitourinary Syndrome of Menopause. Sex Med Rev 2018;6:558-571.

Signs of physical abuse and neglect in the mature patient

Neglect and physical abuse of elderly are worrisome health problems, which are expected to grow even further, considering the aging of the population. By 2060, the number of people aged above 65 years is expected to double, whereas birth rates are low. This trend will cause a significant imbalance between different age groups and put more senior adults at risk for abuse. Risk factors, associated with abuse and neglect, are well established and can be categorized in sociodemographic-, victim-, or perpetrator-related risk factors. The effects of these risk factors depend mainly on the setting, which can be community-dwelling or institutionalized older adults. In community-based settings, 90% of perpetrators are family members. In each setting, suspicious physical injuries should be recognized and addressed promptly. This can be very challenging in elderly, among others, due to the age-related skin changes, which can mimic abuse; however, there are some cutaneous clues that should always raise suspicion of abuse, such as patterned shape or distribution, different healing stages of wounds, parallel injuries, signs of blunt trauma, and irregular patches of alopecia. General awareness is needed, and the advice of dermatologists, who are best trained to differentiate between those lesions, should be systematically sought, to reduce false-positive and false-negative interpretations.

5-Aminolevulinic acid photodynamic therapy in refractory vulvar lichen sclerosus et atrophicus: Series of ten cases

BACKGROUND

Vulvar lichen sclerosus et atrophicus (VLSA) is a chronic inflammatory skin disease of unknown etiology that mainly affects postmenopausal and perimenopausal women. The primary clinical symptoms of VLSA are itching, burning pain, and dyspareunia that can results in decreased quality of life. Existing therapies including topical corticosteroid ointment, topical calcineurin inhibitors, estrogens, are not very effective for treatment of VLSA.

OBJECTIVE

To evaluate the effectiveness and safety of 5-aminolevulinic acid mediated photodynamic therapy (ALA-PDT) in the treatment of VLSA.

MATERIALS AND METHODS

Ten patients with VLSA who had failed conventional treatment received ALA-PDT. 10% 5-ALA in an oil-in-water emulsion was applied to the lesions and occluded with plastic film for 3 h, when the lesions were irradiated with 100 mW/cm2, 635 ± 15 nm red light for 20 min. Treatments were repeated three times at 2-week intervals. Objective and subjective symptoms and signs of the vulvar lesions based on horizontal visual analogue scales were recorded at each treatment and 1, 3, and 6 months after the last session. The quality of life was assessed using dermatology life quality index (DLQI) questionnaire.

RESULTS

All patients completed three ALA-PDT treatments and the follow-up visits. Clinical symptoms of itching disappeared completely in nine patients, one patient had itching decreased from severe to mild. All subjects showed objective improvement in lesions. The DLQI of all cases improved after treatment. The main side-effects of ALA-PDT were pain, erythema, and swelling. Side-effects were transient and tolerable. All patients reported being "satisfied" or "very satisfied" with their outcomes.

CONCLUSIONS

ALA-PDT is an effective and safe approach for the treatment of VLSA.

Lichenoid Dermatitis of the Vulva: Diagnosis and Differential Diagnosis for the Gynecologic Pathologist

Inflammatory processes affecting the vulva may present a unique challenge due to location specific changes. Different factors are behind the intricacy in the presentation of vulvar dermatoses. First, the vulva is lined by different epithelia (hair-bearing keratinized epithelium, modified mucosa, and mucosa). Furthermore, among other factors, this organ is exposed to friction, occlusion, and trauma. Lastly, as there is a tendency to look for health care advice at an advanced stage of the disease, the lesion may be modified by secondary changes due to self-treatment. This article describes the clinical presentation and pathologic features of vulvar dermatoses with a lichenoid pattern and highlights practical points for their diagnoses.

Light and energy based therapeutics for genitourinary syndrome of menopause: Consensus and controversies

Gynecologist and plastic surgeons pioneered the application of lasers in medicine and surgery almost 5 decades ago, initially used to treat cervical and vaginal pathologies. Ever since, energy-based devices have been deployed to treat pelvic pathologies and improve fertility. Recent technological developments triggered an unprecedented wave of publications, assessing the efficacy of fractional laser, and radiofrequency on the vaginal wall in reversing natural aging processes. Studies have shown that a certain degree of thermal energy deposited on the vaginal wall stimulates proliferation of the glycogen-enriched epithelium, neovascularization, and collagen formation in the lamina propria, and improves natural lubrication and control of urination. This review aimed to review such data and to guide future research. A unique assembly of experts from around the globe, compiled and edited this manuscript based on a thorough literature review and personal experience. Lasers Surg.

Turner syndrome: don't forget the vulva

Turner syndrome (TS) has been linked to a number of autoimmune conditions, including lichen sclerosus (LS), at an estimated prevalence of 17%. LS is a known precursor to vulvar cancer. We present a case of vulvar cancer in a 44-year-old woman, who had previously complained of pruritus in the area, a known symptom of LS. Histology confirmed a squamous cell carcinoma with underlying LS. Vulvar assessment for the presence of LS should be undertaken regularly as part of the routine assessments proposed for adult TS women. If LS is identified, then the patient should be warned of the increased risk of vulvar cancer progression and should be monitored closely for signs of the condition.

LEARNING POINTS

Patients with TS are at increased risk of developing LS.LS is a known precursor to vulvar cancer.TS women with LS may be at risk of developing vulvar cancer and should be offered annual vulvar screening and also be aware of signs and symptoms of early vulvar cancer.

Patient Satisfaction of Surgical Treatment of Clitoral Phimosis and Labial Adhesions Caused by Lichen Sclerosus

Introduction

Lichen sclerosus (LS) is a chronic inflammatory dermatosis, usually affecting the anogenital skin in women. This chronic inflammation can cause scarring of genitalia including narrowing of the introitus and phimosis of the clitoris. These architectural changes can lead to recurrent tearing during intercourse (vulvar granuloma fissuratum) and decreased clitoral sensation. Surgical correction of vulvar granuloma fissuratum (VGF) and clitoral phimosis can be performed, but there is little data on the patient satisfaction and complications following these surgical procedures.

Aim

To evaluate patient experience and outcomes in women undergoing surgical correction of scarring caused by anogenital LS.

Methods

A retrospective chart review of patients at a vulvar disorders clinic was performed to identify women who had undergone surgical correction of clitoral phimosis or lysis of vulvar adhesions for VGF due to LS. Twenty‐eight women were contacted via telephone between 4 and 130 months postoperatively. An eight‐question survey was used to determine patient experience and outcomes.

Main Outcome Measures

All participants completed an eight‐question survey to evaluate patient satisfaction with the surgery, effects on clitoral sensation, orgasm and pain with intercourse, postoperative symptoms or complications, and the presence of recurrent vulvar scarring.

Results

Participants reported that they were either very satisfied (44%) or satisfied (40%) with the procedure. Of the women who experienced decreased clitoral sensation prior to surgery, 75% endorsed increased clitoral sensitivity postoperatively. Of the women who had dyspareunia prior to surgery, the majority of women reported having pain‐free sex (33%) or improved but not completely pain‐free sex (58%) after surgery. There were no complications or symptoms made worse by the surgical procedures.

Conclusions

This study shows high patient satisfaction and low complication risk associated with surgical correction of clitoral phimosis and lysis of vulvar adhesions for VGF caused by LS. Patients reported improvement in clitoral sensation and ability to achieve orgasm, as well as decreased dyspareunia. Surgical correction of vulvar scarring is a viable option to restore vulvar anatomy and sexual function in appropriate candidates with anogenital LS.

Extragenital lichen sclerosus et atrophicus along the lines of Blaschko

Lichen sclerosus et atrophicus (LSA) is a chronic inflammatory dermatosis of unknown etiology. Extragenital involvement is uncommon and commonly affects the neck, shoulders, and upper portion of the trunk. It is predominant in women with a male-to-female ratio of 1:6 and occurs at any age. Linear pattern along the lines of Blaschko are seen. There is no cure for LSA. Topical corticosteroids and calcineurin inhibitors, such as tacrolimus, pimecrolimus, PUVA antimalarial agents, and topical retinoids have been tried with varying results.

Pediatric Lichen Sclerosus: A Review of the Epidemiology and Treatment Options

Lichen sclerosus (LS) is a rare, chronic, inflammatory disease of the skin that primarily affects postmenopausal women but may occur in men and children as well. Approximately 7% to 15% of cases are believed to occur in children. The epidemiologic data for LS have been limited and treatment options are not well studied, particularly in children. We reviewed new developments available in the current literature on the epidemiology and management of LS for children.

Evidence-based (S3) Guideline on (anogenital) Lichen sclerosus

Lichen sclerosus (LS) is an inflammatory skin disease that usually involves the anogenital area. All patients with symptoms or signs suspicious of lichen sclerosus should be seen at least once initially by a physician with a special interest in the disease in order to avoid delay in diagnosis, as early treatment may cure the disease in some and reduce or prevent scarring. The diagnosis is made clinically in most cases. Biopsies should only be performed under certain circumstances. The gold standard for treatment remains potent to very potent topical steroids; however, mild and moderate disease in boys and men may be cured by circumcision. Certain triggers should be avoided. http://www.euroderm.org/images/stories/guidelines/2014/S3-Guideline-on-Lichen-sclerosus.pdf http://www.awmf.org/fachgesellschaften/mitgliedsgesellschaften/visitenkarte/fg/deutsche-gesellschaft-fuer-gynaekologie-und-geburtshilfe-dggg.html.

Common vaginal and vulvar disorders

Vaginal and vulvar disorders are among the leading causes for women to visit a health care professional. Therefore, it is important to have a basic understanding of these diseases. Although rarely life threatening, these disorders can impact significantly a woman's sexual function and sense of well-being.

The co-occurrence of lichen sclerosus et atrophicus and celiac disease

A 53-year-old female patient was admitted to our clinic for generalized hypo/hyper-pigmented, partially firm and sclerotic plaques with undefined borders. As the skin biopsy taken from the lesion was compatible with lichen sclerosus et atrophicus (LSA), the patient was treated with ultraviolet A1 (UVA1) treatment. Upon follow-up, she developed abdominal pain and diarrhea. Further investigation (including endoscopic and laboratory tests) showed signs consistent with celiac disease. After 30 sessions of UVA1 treatment, the skin lesions partially regressed. We present this case because the co-occurrence of LSA and celiac disease is very rare.

The impact of vulvar lichen sclerosus on sexual dysfunction

BACKGROUND

Lichen sclerosus (LS) is a chronic inflammatory condition that is known to arise on the vulva. Many women with LS report vulvar pain, often affecting a patient's quality of life. In this study, the sexual function of LS patients, with and without pain, was compared to control populations.

MATERIALS AND METHODS

A case-control study to examine the relationship between LS and sexual dysfunction was conducted. A total of 335 women presenting to the gynecology clinic were included in the study: 197 women with biopsy confirmed LS were compared to two control groups (95 asymptomatic women were "healthy" controls and 43 women had vulvovaginal candidiasis) on self-reported current health complaints, medical and surgical history and current symptoms such as pain and itching, type and frequency of sexual activity, and satisfaction with sexual activity.

RESULTS

Women with LS reported less frequent sexual activity than healthy controls (p=0.007) and Candida controls (p=0.04). Currently sexually active women with LS were significantly less likely to report vaginal intercourse (71.6%) than healthy controls (89.0%, p=0.003) or Candida controls (100%, p=0.0003), even though similar proportions of all three groups reported that vaginal intercourse was important. Satisfaction towards the quality of current sexual activity was significantly lower among women with LS compared with both the healthy and Candida control groups. 23.7% of women with LS reported that sexual activity was rarely or never satisfactory as compared with 0% of healthy controls (p<0.0001) and 6.5% of Candida controls (p=0.03).

CONCLUSION

Women with LS have less frequent sexual activity and less satisfying sexual activity when compared with controls.

A clinicopathological review of 33 patients with vulvar melanoma identifies c-KIT as a prognostic marker

Vulvar melanoma is the second most common vulvar cancer. Patients with vulvar melanoma usually present with the disease at a late stage and have a poor prognosis. The prognostic predictors reported in the literature are not unequivocal and the role of lichen sclerosus and c-KIT mutations in the aetiology of vulvar melanoma is unclear. Breslow staging currently seems to be the most adequate predictor of prognosis. We thus performed a clinicopathological and literature review to identify suitable predictors of prognosis and survival and investigated the expression of c-KIT (by immunohistochemistry) in patients with vulvar melanoma (n=33) from the Gynaecological Cancer Centres of the Royal Hospital for Women (Sydney, Australia) and John Hunter Hospital (Newcastle, Australia). Our series of 33 patients fitted the expected clinical profile of older women: delayed presentation, high stage, limited response to treatment and poor prognosis. We identified 3 patients (9.1%) with lichen sclerosus associated with melanoma in situ, although no lichen sclerosus was found in the areas of invasive melanoma. No patient had vulvar nevi. We identified a) Breslow's depth, b) an absence of any of the pathological risk factors, such as satellitosis, in-transit metastasis, lymphovascular space invasion (LVSI) and dermal mitosis, c) removal of inguino-femoral lymph nodes, d) lateral margin of >1 cm, and e) c-KIT expression as valuable prognostic predictors for disease-free survival. We conclude that c-KIT expression is, apart from Breslow's depth, another valuable predictor of prognosis and survival. Lichen sclerosus may be associated with vulvar melanoma.

Isolated, localised extragenital bullous lichen sclerosus et atrophicus: a rare entity

Lichen sclerosus et atrophicus (LSA) is a rare, chronic, mucocutaneous disease of unknown cause. Onset can occur in subjects of any age but more prevalent in adult females around the time of menopause. In both the sexes anogenital involvement is more common. Extragenital cases are rare, and common localizations are neck and shoulders, axilla, upper arms, flexor aspects of wrists and around the umbilicus. Bullous LSA is an unusual manifestation of the disease. Isolated extragenital bullous LSA is a distinctly rare event with very few cases reported till date.

Low-concentration topical tacrolimus for the treatment of anogenital lichen sclerosus in childhood: maintenance treatment to reduce recurrence

BACKGROUND

Lichen sclerosus (LS) is a chronic inflammatory skin disorder that is commonly found in the anogenital area, especially in females. Ultra-potent topical corticosteroids are first line for the treatment of LS, but their atrophic side effects and the recurrence of the disease restrict their use. An equally effective, safer, tolerant therapeutic option is required, especially in the treatment and preventing relapse of children.

METHODS

Fourteen prepubertal girls (range of age: 4 to 11 years) with anogenital lichen sclerosus were treated with 0.03% tacrolimus ointment twice daily for 16 weeks, then 9 of the 14 patients adhered to 2 times weekly for further 6 months (a total of 10 months). The therapeutic effects were evaluated according to 3 grades: complete response (O75% improvement, partial response (30%-75% improvement),or no response (!30% improvement).

RESULTS

Clinical improvement occurred in all patients (100%). Complete response of symptoms and signs was achieved in 5 (36%), 9 (64%) and 11 (79%) patients at week 8, week 16, and month 10 respectively. During the follow-up period of 1 year, 4 patients (4/5, 80%) who treated with tacrolimus ointment for 16 weeks had a recurrence of symptoms, while only 2 of 9 (22%) patients who insisted on maintenance therapy developed recurrence of disease. No severe side effects were observed.

CONCLUSIONS

Low-concentration topical tacrolimus appears to be an effective and safe treatment for children with anogenital lichen sclerosus. Maintenance therapy (2 times a week for 6 months) can reduce the relapse of the disease.

Squamous cell carcinoma of the vulva: a comparison between women 35 years or younger and 90 years or older

OBJECTIVE

This study aimed to compare clinical features, diagnosis, management, and outcomes between women 35 years or younger and 90 years or older with vulvar squamous cell carcinoma referred to Queensland Centre for Gynaecological Cancer between 1983 and 2010.

MATERIALS AND METHODS

Fifty-seven case records, including pathology reports for these 2 groups were reviewed and analyzed using the computer software SPSS 11.0.

RESULTS

Of the cases, 34 were 35 years or younger (mean = 31.6 years), and 23 90 years or older (mean = 92.6 years). International Federation of Gynecology and Obstetrics classification showed grade 1 for 74% in the younger group and 55% for the older group. Patient status showed 22 alive (65%) in the younger group and 4 alive (17%) in the older group. Three younger patients (9%) were dead of disease and 8 (35%) in the older group. Three patients (9%) died of another disease in the younger group and 10 patients (43%) in the older group. Initial treatment was surgical in 30 younger cases (88%) and 18 older cases (78%).

CONCLUSIONS

We demonstrated a trend toward younger women presenting with vulvar squamous cell carcinoma and a history of human papillomavirus and vulvar intraepithelial neoplasia. Immune deficiency diseases occurred in 23% of the younger group, but none occurred in the older group, where Alzheimer disease, heart disease, and renal failure (57%) were present. Poorly differentiated tumors and an International Federation of Gynecology and Obstetrics classification of 2 or more resulted in a worse outcome than did better differentiated lesions, irrespective of additional medical conditions.

Treatment of male genital lichen sclerosus with clobetasol propionate and maintenance with either methylprednisolone aceponate or tacrolimus: a retrospective study

OBJECTIVE

To assess the efficacy of clobetasol propionate 0.05% cream in male patients suffering from genital lichen sclerosus (GLS), as well as the efficacy of methylprednisolone aceponate 0.1% cream and tacrolimus 0.1% ointment as maintenance therapy.

METHODS

The study was conducted retrospectively. At baseline, male patients with GLS (n = 41) were treated with clobetasol propionate 0.05% cream applied twice daily for 8 weeks. Visual Analog Scale (VAS) score for pruritus, Investigator's Global Assessment (IGA) score and Dermatology Life Quality Index (DLQI) were recorded at baseline, week 8 and week 20. At week 8, patients responsive to treatment (n = 37) were further treated with methylprednisolone aceponate 0.1% cream twice weekly (n = 17) or tacrolimus 0.1% ointment once daily (n = 20), as maintenance therapy until week 20.

RESULTS

VAS, IGA and DLQI median scores were significantly decreased from baseline to week 8 (p < 0.001). At week 20, patients treated with methylprednisolone aceponate 0.1% cream presented no significant difference in median IGA score (p = 0.865), median DLQI score (p = 0.853) or median VAS score (p = 0.474) compared with patients treated with tacrolimus 0.1% ointment.

CONCLUSIONS

Clobetasol propionate 0.05% cream is effective as first-line treatment in male GLS. The data suggest that there is no difference between methylprednisolone aceponate 0.1% cream and tacrolimus 0.1% ointment in preventing the relapses.

Lichen sclerosus in a breast cancer survivor on an aromatase inhibitor: a case report

Lichen sclerosus is a commonly misdiagnosed disease that is characterized by thinned, hypopigmented, crinkled skin that often forms a figure-eight shape around the vaginal and anal openings. We present a case of advanced lichen sclerosus in a 53-year-old female patient prescribed a nonsteroidal aromatase inhibitor after the excision of a breast cancer tumor. We present a diagnostic approach to lichen sclerosus by recognizing its common figure-eight pattern, and we review the known causes and treatment of lichen sclerosus. Research has shown that lichen sclerosus is more common in low estrogen states, and thus it is logical that aromatase inhibitors could increase a patient's risk for developing this disease. We therefore propose that all patients prescribed aromatase inhibitors undergo regular vulvo-vaginal exams to rule out lichen sclerosus and other hypoestrogen-related vulvo-vaginal problems.
