EuroGuiderm guideline on lichen sclerosus-introduction into lichen sclerosus.

INTRODUCTION: Lichen sclerosus (LS) is an inflammatory skin disease affecting all ages. LS typically involves the anogenital site where it causes itching and soreness. It may lead to sexual and urinary dysfunction in females and males; however, it may be asymptomatic. First signs of LS are redness and oedema, typically followed by whitening of the genital skin; sometimes fissuring, scarring, shrinkage and fusion of structures may follow in its course. LS is associated with an increased risk of genital cancer. LS has a huge impact on the quality of life of affected patients, and it is important to raise more awareness of this not uncommon disease in order to diagnose and treat it early. OBJECTIVES: The guideline intends to provide guidance on the diagnostic of LS, highlight important aspects in the care of LS patients (part 1), generate recommendations and treatment algorithms (part 2) on topical, interventional and surgical therapy, based on the latest evidence, provide guidance in the management of LS patients during pregnancy, provide guidance for the follow-up of patients with LS and inform about new developments and potential research aspects. MATERIALS AND METHODS: The guideline was developed in accordance with the EuroGuiDerm Methods Manual v1.3 https://www.edf.one/de/home/Guidelines/EDF-EuroGuiDerm.html. The wording of the recommendations was standardized (as suggested by the GRADE Working Group). The guideline development group is comprised of 34 experts from 16 countries, including 5 patient representatives. RESULTS: Ultrapotent or potent topical corticosteroids in females and males, adults and children remain gold standard of care for genital LS; co-treatment with emollients is recommended. If standard treatment fails in males, a surgical intervention is recommended, complete circumcision may cure LS in males. UV light treatment is recommended for extragenital LS; however, there is limited scientific evidence. Topical calcineurin inhibitors are second line treatment. Laser treatment, using various wave lengths, is under investigation, and it can currently not be recommended for the treatment of LS. Treatment with biologics is only reported in single cases. CONCLUSIONS: LS has to be diagnosed and treated as early as possible in order to minimize sequelae like scarring and cancer development. Topical potent and ultrapotent corticosteroids are the gold standard of care; genital LS is often a lifelong disease and needs to be treated long-term.

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.

Penoscrotal Paget's disease.

Paget's disease (PD) denotes an initially intra-epidermal adenocarcinoma that can later invade the dermis and metastasise. Among the extramammary forms of PD (EMPD), penoscrotal presentations are rarer than the vulvar and perianal forms. Once diagnosis has been confirmed by histopathological examination, a search for associated neoplasia must be conducted, although penoscrotal EMPD is less frequently associated with underlying neoplasia than mammary PD (MPD). The associated cancer most often involves a neighbouring organ, with prostate cancer being the most common, or in some cases consists of underlying cutaneous adnexal tumours. First-line therapy consists of surgical excision. Alternatives to surgery (imiquimod, CO2 laser vaporisation, dynamic phototherapy) may be considered in certain cases.

[Penile malakoplakia associated with lichen sclerosus]. / Malakoplakie du pénis associée à un lichen scléreux.

INTRODUCTION: Malakoplakia is a granulomatosis of infectious origin in reaction to a chronic bacterial infection (most commonly urinary Escherichiacoli) related to an acquired phagocytosis impairment. PATIENTS AND METHODS: We report a case of penile malakoplakia in a 69-year-old man with lichen sclerosis and stenosis of the urinary meatus leading to recurrent urinary tract infections. The clinical aspect was suggestive of squamous cell carcinoma of the glans developing on lichen sclerosus, but histological examination revealed penile malakoplakia. DISCUSSION: Malakoplakia of the genital mucosa is rare, with only one case of involvement of the glans being reported in the literature. The association with lichen sclerosus is probably not fortuitous but could in fact be due to chronic urinary tract infection favored by stenosis of the urethral meatus and possible local immunodepression following prolonged application of clobetasol. CONCLUSION: We report a case of penile malakoplakia associated with chronic E. coli urinary tract infection, due originally to associated genital lichen sclerosus.

Psoriasis and male sexuality.

Since sexual satisfaction is a key factor in quality-of-life scores, the aim of this review article is to examine current knowledge concerning the impact on male sexuality of psoriasis, particularly genital psoriasis. Risk factors for sexual dysfunction, and more specifically erectile dysfunction, demonstrated to date include severity of psoriasis, genital psoriasis, psoriatic arthritis, smoking, psychological disorders (anxiety-depression), cardiovascular comorbidities and side effects of psoriasis treatments. Studies evaluating the burden of genital psoriasis on male sexuality are contradictory: while the link between genital psoriasis and global sexual functioning has been clearly established in relation to question 9 of the DLQI, discrepancies exist between the scoring systems used concerning sexual satisfaction. Finally, psoriasis patients have expressed a wish to receive more care from their dermatologist in terms of their genital psoriasis and its impact on their sexual activity.

[Penile intra-epithelial neoplasia]. / Les néoplasies intra-épithéliales du pénis.

INTRODUCTION: Penile intra-epithelial neoplasia (PIN) are precancerous lesions, characterized by architectural and cytological abnormalities of the genital epithelium, from which can arise squamous carcinomas. METHODS: A literature review was performed on the Medline database, considering the articles listed between October 2007 and October 2017 dealing with PIN, using the following keywords "intraepithelial neoplasia" or "Bowen's disease" or "erythroplasia of Queyrat" or "bowenoid papulosis" and "penis ¼. Papers were selected according to their language (English and French) and their relevance. RESULTS: One hundred seventy four articles related to PIN were listed. Twenty-five of them were selected for their relevance. The analysis of the references of these articles identified 6 relevant papers published before October 2007, which were considered for this review based on a total of thirty-one articles. We describe clinical and pathological characteristics of PIN, emphasizing treatment modalities. CONCLUSION: Urologists should distinguish HPV-related and non HPV-related PIN, both of them sharing clinical presentation, but needing different management.

[Abnormalities of the male median raphe]. / Anomalies du raphé médian chez l'homme.

INTRODUCTION: Abnormalities of the male median raphe can either be detected during postnatal examination or appear later during childhood or adulthood. They can be isolated or sometimes associated with severe congenital genitourinary malformations. METHODS: A literature review was performed on the Medline database, considering the articles listed until April 2015 dealing with abnormalities of the male median raphe using the following keywords: male, median raphe and abnormalities. Papers were selected according to their language (English and French) and their relevance. RESULTS: Forty-one articles related to male median raphe abnormalities were listed. Five of them were selected for their relevance. We describe frequent median raphe abnormalities (hyperpigmentation, deviation, division, cyst, canal and sinus), emphasizing the clinical aspects, the explorations, the risk of associated genitourinary abnormalities and the treatment. DISCUSSION: Male raphe abnormalities should be known by the urologists since functional, infectious and aesthetic complications could lead patients to consultation.
