Screening for precancerous anal lesions linked to human papillomaviruses: French recommendations for clinical practice.

In France, about 2000 new cases of anal cancer are diagnosed annually. Squamous cell carcinoma is the most common histological type, mostly occurring secondary to persistent HPV16 infection. Invasive cancer is preceded by precancerous lesions. In addition to patients with a personal history of precancerous lesions and anal cancer, three groups are at very high risk of anal cancer: (i) men who have sex with men and are living with HIV, (ii) women with a history of high-grade squamous intraepithelial lesions (HSILs) or vulvar HPV cancer, and (iii) women who received a solid organ transplant more than 10 years ago. The purpose of screening is to detect HSILs so that they can be treated, thereby reducing the risk of progression to cancer. All patients with symptoms should undergo a proctological examination including standard anoscopy. For asymptomatic patients at risk, an initial HPV16 test makes it possible to target patients at risk of HSILs likely to progress to cancer. Anal cytology is a sensitive test for HSIL detection. Its sensitivity is greater than 80% and exceeds that of proctological examination with standard anoscopy. It is indicated in the event of a positive HPV16 test. In the presence of cytological abnormalities and/or lesions and a suspicion of dysplasia on clinical examination, high-resolution anoscopy is indicated. Performance is superior to that of proctological examination with standard anoscopy. However, this technique is not widely available, which limits its use. If high-resolution anoscopy is not possible, screening by a standard proctological examination is an alternative. There is a need to develop high-resolution anoscopy and triage tests and to evaluate screening strategies.

Mycoplasma genitalium screening in a specialized French unit: A retrospective study.

OBJECTIVE: Mycoplasma genitalium (MG) infection accounts for 10-35% of non-gonococcal non-chlamydial (NGNC) urethritis. However, given that most people infected with MG do not develop symptoms and that antimicrobial resistance is increasing worldwide, there is no evidence of any benefits of screening asymptomatic individuals. We conducted this study to describe MG screening practices and outcomes at a French Sexually Transmitted Infections (STI) center in which MG testing was performed selectively and multiplex assays were not carried out [i.e., simultaneous screening for Chlamydia trachomatis (CT), Neisseria gonorrhoeae (NG), and MG]. METHODS: A retrospective, observational, single-center study was conducted at the STI unit of Saint-Louis Hospital in Paris. The records of all patients undergoing MG testing from January 1st, 2017, to December 31st, 2018, were reviewed. The primary aim of the study was to describe and evaluate the proportion of MG-positive (MG+) patients among those tested. Secondary objectives were determination of the prevalence of MG+ status among symptomatic patients, risk factors associated with MG infection, and therapeutic modalities and efficacy. RESULTS: Two hundred and forty-nine patients underwent MG testing, 28 (11%) of whom were positive (MG+). The prevalence of MG+ status among symptomatic NGNC patients was 12%. HIV-positive (HIV+) status was significantly associated with MG+ status in univariate and multivariate analyses (Odds Ratio=7.3, 95% Confidence Interval 1.3-41.7; P=0.02). Twenty-three patients (85%) received antibiotics. Eighteen (67%) received azithromycin for 5 days, but 7 had clinical resistance. No quinolone resistance was reported. CONCLUSION: Despite unavailability of multiplex testing at our facility, which led to targeted-only screening for MG, its relatively high local prevalence is in keeping with what is generally observed at similar facilities across the world, where use of multiplex tests enables systematic screening for MG alongside NG and CT. This reinforces the current recommendations in Europe, France and the US against systematic MG testing or treatment in asymptomatic patients.

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.

Haemophilus parainfluenzae-related cellulitis of the penis following tearing of a short frenulum.

INTRODUCTION: Infectious cellulitis is a common disease, mostly affecting the lower extremities and the face but only rarely the genitalia. OBSERVATION: A 24-year-old male patient presented with acute erythematous edema of the penile shaft and foreskin present for 48hours. Gentle retraction of the foreskin revealed a short frenulum with a small area (2-3mm) of erosion. He had had unprotected genital and orogenital sex three days before with his usual female partner and reported tearing of the frenulum during intercourse. Ampicillin-sensitive Haemophilus parainfluenzae was isolated from the swab taken from the erosion of the frenulum. Clinical remission was obtained following oral administration of amoxicillin and clavulanic acid. DISCUSSION: We describe not only the first case of Haemophilus parainfluenzae-associated cellulitis of the penis but also the first report of penile cellulitis following erosion of a short frenulum during sexual intercourse.
