Peno-gingival lichen planus

2022 European guideline for the management of balanoposthitis

BACKGROUND

This guideline is an update to the 2014 edition of the European guideline for the management of balanoposthitis. Balanoposthitis describes inflammation of the glans penis and prepuce and is caused by a range of disparate conditions including infection, dermatoses and premalignancy.

OBJECTIVE

The main objectives of this guideline are to aid recognition of the symptoms and signs and complications of penile skin conditions and to offer recommendations on the diagnostic tests and treatment for a selected group of these conditions.

METHODS

The previous guideline was updated following a literature review and priority was given to randomized controlled trial and systematic review evidence.

RESULTS

The updated guideline includes amended management for infective balanitis to provide clear guidance for Group A streptococcal infections, management of on going Lichen sclerosus (to include circumcision and supportive management to reduce the recurrence of genital herpes and warts), additional regimens for Zoonoid change, use of calcineurin inhibitors in management and risk of premalignancy and change of nomenclaturefrom Premalignant conditions to Penile Intraepithelial neoplasia (PeIN).

CONCLUSION

Balanoposthitis has a widerange of causes high quality evidence specific to the management of penile disease is not available for all the conditions described.

French guidelines for the management of oral lichen planus (excluding pharmacological therapy)

INTRODUCTION

Oral lichen is a chronic inflammatory disease for which diagnostic management and follow-up are heterogeneous given the absence of specific guidelines in France. Our objective was to develop French multidisciplinary guidelines for the management of oral lichen.

MATERIALS AND METHODS

Working groups from the Groupe d'Etude de la Muqueuse Buccale (GEMUB) formulated a list of research questions and the corresponding recommendations according to the "formal consensus" method for developing practice guidelines. These recommendations were submitted to a group of experts and the degree of agreement for each recommendation was assessed by a scoring group.

RESULTS

Twenty-two research questions, divided into 3 themes (nosological classification and initial assessment, induced oral lichenoid lesions, and follow-up) resulted in 22 recommendations. Initial biopsy for histology is recommended in the absence of reticulated lesions. Biopsy for direct immunofluorescence is recommended for ulcerated, erosive, bullous types and for diffuse erythematous gingivitis. Management should include a periodontal and dental check-up, and investigation for extra-oral lesions. Hepatitis C testing is recommended only if risk factors are present. Definitions, triggering factors and the management of "induced oral lichenoid lesions" were clarified. Oral lichen must be monitored by a practitioner familiar with the disease at least once a year, using objective tools.

CONCLUSION

This formalised consensus of multidisciplinary experts provides clinical practice guidelines on the management and monitoring of oral lichen.

Male genital lichen planus: A retrospective study of 89 cases

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.

Genital lichen planus: An underrecognized entity

Genital lichen planus (LP) is an underrecogonized dermatosis. The appearance is often unlike classical LP elsewhere, and hence, the condition goes undiagnosed in many. Vulvo-vaginal LP in particular, can be a distressing condition often leading to scarring and a poor quality of life. Treatment for most of the genital LP variants is similar to managing LP elsewhere; however, the erosive variant requires special attention as treatment outcomes are often disappointing and the disease runs a protracted course. Potential for development of malignancy also exists, as in oral LP, and hence close follow up is essential.

Clinical and epidemiological profile of patients attended in a vulvar clinic of the dermatology outpatient unit of a tertiary hospital during a 4-year period

BACKGROUND

Vulvar complaints are among the most frequent causes for a woman to visit a healthcare provider. The diseases of this area of the body may be a challenge to diagnose. In this study, we assess epidemiologic and clinical data of patients in an outpatient vulvar clinic in the dermatology department of a tertiary hospital.

METHODS

We performed an observational retrospective study of patients who attended our consultation service for vulvar diseases at the Dermatology Division at Hospital das Clínicas da Faculdade de Medicina da USP during a 4-year period. Data were obtained by patient medical records and by phone.

RESULTS

During the 4-year period under study, a total of 136 patients were treated in the outpatient service specialized in vulvar care. All patients were included in the study. The most frequent diagnoses were lichen sclerosus et atrophicus (64.7%), lichen planus (8.8%), and vitiligo (8%). We registered that 26.7% of the patients showed extravulvar involvement.

CONCLUSIONS

Women with vulvar diseases need specific care, considering not only genital aspects but also all skin changes. In this context, the dermatologist is a very well trained professional to take good and complete care of these patients. However, ideally vulvar clinics should have a multidisciplinary team.

Vulvovaginal gingival lichen planus: report of two cases and review of literature

PURPOSE

Oral Lichen Planus (OLP) is a chronic inflammatory disease of skin and mucous membranes. Approximately 20% of women with oral lichen planus develops lesions in the genital mucosa. In 1982, Pelisse described a special form of lichen planus (LP), which consists of a triad of symptoms: vulval, vaginal and gingival (VVG)-LP lesions. Aim of the present report is to report two new cases and review the international literature.

MATERIAL AND METHODS

Two cases of VVG-LP are reported and a review of recent literature is performed.

RESULTS

The onset of erosive or ulcerative mouth lesions may precede or follow by months or even years the onset of vulvovaginal lesions. Vaginal agglutination is associated with the postmenopausal state in conjunction with a dermatologic condition. Intra-lesional corticosteroids have a role in localized chronic ulceration, while systemic therapies such as corticosteroids, azathioprine, mycophenolate mofetil, hydroxychloroquine, ciclosporin, methotrexate, retinoids, thalidomide and photo chemotherapy have been used in more severe cases with varying success.

CONCLUSIONS

VVG-LP is rather a rare condition and has been documented in the literature mainly in the form of case reports. Lack of a precise diagnostic criteria of VVG-LP depends on the specialists.

Oral lichen planus clinical characteristics in Italian patients: a retrospective analysis

Background

Oral lichen Planus (OLP) is a chronic inflammatory disease involving skin and mucous membranes. Its etiology is still uncertain whilst an autoimmune mechanism is known to be implicated. OLP is commonly considered a geriatric disease and gender differences in prevalence are clear, whereby females are generally more frequently affected than males more often during the 5th and 6th decades of life. Lesions are symmetrical and bilateral and the buccal mucosa is frequently involved. The risk of malignant transformation is extremely low.

This study aims to describe both the clinical characteristics and the prevalence of OLP among a group of patients from Southern Italy. The results of the present study were compared to analogous retrospective studies.

Methods

Eighty-seven (31 man and 56 woman) cases of OLP were retrospectively reviewed and demographic and clinical data were collected. Data about OLP as clinical forms, oral and extraoral sites involved and Visual Analogue Scale were also recorded.

Results

The average age of OLP onset was 59.2 years. The most common clinical presentation was the hyperkeratosic type. Symptomatic OLP was noted in 26.8 % of the patiens. The most frequently affected oral sites were buccal mucosa, tongue, gums. The most frequently associated systemic diseases were diabetes, hypertension, C hepatitis and thyroiditis. Only one patient developed a malignant transformation (1.2 %).

Conclusions

Previous retrospective studies report data partially comparable with our results. Different geographic area, number of enrolled patients and OLP classification criteria may justify the observed differences.

2013 European guideline for the management of balanoposthitis

Balanoposthitis can be caused by a disparate range of conditions affecting the penile skin. This guideline concentrates on a selected group of conditions and offers recommendations on the diagnostic tests and treatment regimens needed for the effective management of balanoposthitis.

Lichen planus of the external urinary meatus masquerading sexually transmitted disease

Lichen planus is a chronic inflammatory mucocutaneous disorder of the skin including the scalp, the nails, and the oral and genital mucosae. Ocular, oesophageal, bladder, nasal, laryngeal, otic, gastric, and anal involvement has been documented. In this report, we describe a unique case of orogenital lichen planus affecting the external urinary meatus, masquerading as sexually transmitted urethritis and erosive genital disease.

Topical immunomodulators for management of oral mucosal conditions, a systematic review; part I: calcineurin inhibitors

IMPORTANCE OF THE FIELD

Topical immunomodulators have been used for the management of oral mucosal diseases. Topical immunomodulating preparations may have utility in local management of oral disease which is resistant to topical steroids and oral findings of an immunologic-mediated systemic disease with primary or persisting, oral mucosal involvement.

AREAS COVERED IN THIS REVIEW

This paper is the first part of a systematic review of topical immunomodulators for the management of various oral indications focused on calcineurin inhibitors. The literature search revealed that data are available for cyclosporine, tacrolimus and pimecrolimus. In addition to the review of scientific evidence, this paper presents the potential market, the mechanism of action, the competitive environment and future development options.

WHAT THE READER WILL GAIN

The reader will find weighted conclusions for the topical use of the calcineurin inhibitors in the management of oral diseases.

TAKE HOME MESSAGE

Topical calcineurin inhibitors may be useful as a second-line treatment in several oral diseases, particularly oral lichen planus.

Oro-genital lichen planus: report of two cases

Lichen planus is a common mucocutaneous disease. However, lichen planus with concomitant oral and genital involvement is a rare condition that requires multidisciplinary intervention for appropriate diagnosis. In this study, we reported two cases of oro-genital lichen planus in a man and a woman. Analyses of oral and genital lesions were clinically and histopathologically compatible with lichen planus. This description highlights the importance of patients presenting oral lichen planus be routinely required to undergo further medical examination in order to investigate putative genital mucosal involvement. These lesions have the potential to progress to neoplasia. Therefore, medical and dentistry professionals should be aware of this condition.
