Review
Lichen sclerosus (LS) is an underdiagnosed inflammatory mucocutaneous condition affecting the anogenital areas. Postmenopausal women are predominantly affected and, to a lesser extent, men, prepubertal children, and adolescents. The etiology of LS is still unknown. Hormonal status, frequent trauma and autoimmune diseases are well-known associations for LS, yet infections do not seem to be clear risk factors. LS pathogenesis involves factors such as a genetic predisposition and an immune-mediated Th1-specific IFNγ-induced phenotype. Furthermore, there is a distinct expression of tissue remodeling associated genes as well as microRNAs. Oxidative stress with lipid and DNA peroxidation provides an enabling microenvironment to autoimmunity and carcinogenesis. Circulating IgG autoantibodies against the extracellular matrix protein 1 and hemidesmosome may contribute to the progression of LS or simply represent an epiphenomenon. The typical clinical picture includes chronic whitish atrophic patches along with itching and soreness in the vulvar, perianal and penile regions. In addition to genital scarring, and sexual and urinary dysfunction, LS may also lead to squamous cell carcinoma. Disseminated extragenital LS and oral LS are also reported. The diagnosis is usually clinical; however, a skin biopsy should be performed in case of an unclear clinical picture, treatment failure or suspicion of a neoplasm. The gold-standard therapy is the long-term application of ultrapotent or potent topical corticosteroids and, alternatively, topical calcineurin inhibitors such as pimecrolimus or tacrolimus. Collectively, LS is a common dermatological disease with a so far incompletely understood pathogenesis and only limited treatment options. To foster translational research in LS, we provide here an update on its clinical features, pathogenesis, diagnosis and (emerging) treatment options.

Review
Lichen sclerosus (LS) is a chronic, inflammatory, mucocutaneous disorder of genital and extragenital skin. LS is a debilitating disease, causing itch, pain, dysuria and restriction of micturition, dyspareunia, and significant sexual dysfunction in women and men. Many findings obtained in recent years point more and more towards an autoimmune-induced disease in genetically predisposed patients and further away from an important impact of hormonal factors. Preceding infections may play a provocative part. The role for Borrelia is still controversial. Trauma and an occlusive moist environment may act as precipitating factors. Potent and ultrapotent topical corticosteroids still head the therapeutic armamentarium. Topical calcineurin inhibitors are discussed as alternatives in the treatment of LS in patients who have failed therapy with ultrapotent corticosteroids, or who have a contraindication for the use of corticosteroids. Topical and systemic retinoids may be useful in selected cases. Phototherapy for extragenital LS and photodynamic therapy for genital LS may be therapeutic options in rare cases refractory to the already mentioned treatment. Surgery is restricted to scarring processes leading to functional impairment. In men, circumcision is effective in the majority of cases, but recurrences are well described. Anogenital LS is associated with an increased risk for squamous cell carcinoma of the vulva or penis. This review updates the epidemiology, clinical presentation, histopathology, pathogenesis, and management of LS of the female and male genitals and extragenital LS in adults and children.

Review
Lichen sclerosus (LS), or balanitis xerotica obliterans as it was previously known, is a chronic inflammatory lymphocyte-mediated scarring dermatosis that often affects the preputial skin and glans, leading to phimosis and urethral strictures if left untreated. We present a narrative review of the literature assessing its aetiology and pathogenesis and discuss its links to penile cancer and its medical and surgical management. Possible hypotheses for the development of LS include chronic exposure to trapped urine, leading to changes in the epithelial structure. This is supported by the fact that circumcision is often curative in the early stages of the disease. Although circumcision can be curative, the use of topical steroids is typically the first-line treatment and may preserve the foreskin and forgo the need for circumcision altogether. Patients should be made aware of a possible association with penile cancer. Although the majority of cases can be treated by medical therapy and circumcision, a significant number of patients may also require penile reconstructive procedures.

Review
Role of male circumcision (MC) as a tool to prevent sexually transmitted infections (STIs)/human immunodeficiency virus (HIV) was assessed. An attempt was made to search articles related to association between MC and STIs/HIV. A thorough search was carried out to find out quality articles published in indexed specialty journals. Centers for Disease Control and Prevention and World Health Organization (WHO) sites were also referred. Warm and moist environment of area under foreskin facilitates some pathogens to persist and replicate. Further, the thinness of foreskin predisposes it to minor trauma and abrasions that facilitate the entry of pathogens. MC reduces HIV infection risk by 50%-60% over time and reduces the risk of men acquiring herpes simplex virus-2 and human papillomavirus (HPV) that can cause penile and other anogenital cancers, by 30%. There is no significant reduction in risk of acquiring syphilis, but reduced risk of acquisition of is reported. MC is reported to be beneficial in conditions such as traumatic injury, Balanitis Xerotica Obliterans, refractory balanoposthitis, and chronic, recurrent urinary tract infections. MC also reduces the chances of penile carcinoma by facilitating improved penile hygiene, lowering HPV/HIV transmission rates, and reducing chronic inflammatory conditions such as phimosis and balanitis. MC has been recommended by the WHO and UNAIDS in 2007 as an additional HIV prevention intervention in settings of high HIV prevalence. MC is an important adjunct to safe sex education, condom use, and vaccination (HPV) in reducing the global burden of HIV/STIs-related morbidity and mortality.

INTRODUCTION
Buried penis is a condition that causes the penis to become hidden beneath the skin. It has a significant impact on quality of life and can present in a variety of ways, with lower urinary tract symptoms and erectile dysfunction being common. Whilst there are several causes, obesity is the most common in adults. Due to the burden that obesity is increasingly presenting to healthcare, buried penis may become more common in the future.The purpose of this article is to provide an overview of the causes, presentation and surgical management of this condition in adults.
MATERIAL AND METHOD
A literature review was conducted using urological and plastic surgery articles from PubMed, Embase and Medline. Eighteen studies, published between 1982 and 2016, were included.
RESULTS
Original research trials discussed the treatment of buried penis in lymphoedema and balanitis xerotica obliterans (BXO), new techniques for fat removal, comparison of grafts and postoperative dressings. Several studies provided broad overviews, although focused on management rather than cause and presentation. Overall, studies suggest that, whilst some causes can only be treated with surgery, others can be modified by lifestyle changes and medical management.
CONCLUSIONS
Buried penis is a complex condition that may take years to treat. Several surgical techniques are available, with patients likely requiring a combination of techniques to treat this problem. This review aims to provide a comprehensive overview of the causes, presentation and surgical management of this condition, in order to further the understanding of clinicians who may be faced with this problem more commonly in the future.

Review
Scleroderma-like cutaneous lesions have been found in many pathological conditions and they have the clinical appearance of sclerotic or scleroatrophic lesions. Affected skin biopsies described histopathological changes similar to those of scleroderma located strictly on the skin or those of systemic sclerosis. These skin lesions can be found in inflammatory diseases with autoimmune substrate (generalized morphea, chronic graft versus host disease, eosinophilic fasciitis), tissue storage diseases (scleredema, scleromyxedema, nephrogenyc systemic fibrosis, systemic amyloidosis), metabolic diseases (porphyrya cutanea tarda, phenylketonuria, hypothyroidism, scleredema diabeticorum), progeroid syndromes. Given the multiple etiologies of sclerodermal lesions, a correct differential diagnosis is necessary to establish the appropriate treatment.

Review
Adult acquired buried penis represents the clinical manifestation of a wide spectrum of pathology due to a variety of etiologies. It can be related to obesity, a laxity in connective tissue, lichen sclerosis (LS), complications from penile/scrotal enlargement surgery, scrotal lymphedema, or hidradenitis suppurativa (HS). Buried penis can be associated with poor cosmesis and hygiene, voiding dysfunction, and sexual dysfunction. Evaluation and management of buried penis largely depends on etiology and degree of affected tissue. It is an increasingly common problem seen by reconstructive urologists and here we present several frequently seen scenarios of buried penis and management options.

International Braz J Urol : Official... 2015To review the technique and outcome of perineal urethrostomy or urethral perineostomy and to identify factors related to the procedure failure.
OBJECTIVE
To review the technique and outcome of perineal urethrostomy or urethral perineostomy and to identify factors related to the procedure failure.
MATERIAL AND METHODS
We studied 17 patients who underwent perineal urethrostomy between 2009-2013 in a single hospital. Success was defined as no need for additional surgical treatment or urethral dilatation. We reviewed the clinical data related to age, weight, previous urethral surgery, diabetes, hypertension, ischemic cardiopathy, lichen sclerosus and other causes and studied their association with the procedure failure (univariate analysis). We completed the analysis with a multivariate test based on binary regression.
RESULTS
The average follow-up was 39.41 months. From all the causes, we found Lichen Sclerosus in 35 %, idiopathic etiology in 29 % and prior hypospadia repair in 18 %. Postoperative failure occurred in 3 patients, with a final success of 82.4 %. The binary regression model showed as independent risk factors ischemic cardiopathy (OR: 2.34), and the presence of Lichen Sclerosis (OR: 3.21).
CONCLUSIONS
The success rate with the perineal urethrostomy technique shows it to be a valid option above all when we preserve the urethral blood supply and plate. Lichen sclerosus and ischemic vascular problems are risk factors to re-stenosis.
