Incidence of preputial lichen sclerosus in adults: histologic study of circumcision specimens

Lichen Sclerosus and Phimosis - Discrepancies Between Clinical and Pathological Diagnosis and Its Consequences

OBJECTIVE

To assess the accuracy of clinical diagnoses and the true incidence of lichen sclerosus (LS) in patients with phimosis.

MATERIALS AND METHODS

The 92 adult male patients who were qualified for circumcision due to phimosis, were included in the study. The patients were diagnosed clinically by a urologist and dermatologist before the surgical procedure. After the circumcision, the resected foreskins were examined by 2 independent uropathologists.

RESULTS

Preoperative clinical diagnosis of LS was established in 54 patients (58.7%); healthy-looking skin in 26 (28.3%) and other penile diseases in 12 (13.1%) patients. After histopathological examination, the diagnosis of LS was established in 62 patients (67.4%), but only in 44 patients with previous LS clinical diagnosis. LS was histopathologically confirmed in 18 other patients with clinically diagnosed healthy skin (n = 17) or lichen planus (n = 1). Healthy skin was histopathologically confirmed in 10 cases in patients diagnosed clinically before as LS. Other 15 histopathological diagnoses were Zoon balanitis (n = 3), nonspecific balanitis (n = 5), lichen planus (n = 1), psoriasis (n = 1), invasive penile cancer (n = 3), Bowen's disease (n = 1), penile intraepithelial neoplasia 2 usual type (n = 1).

CONCLUSION

LS has been revealed as the most common histopathological diagnosis in patients undergoing circumcision in our study. Histopathological examination seems to be necessary to exclude this disease.

Anogenital lichen sclerosus

Lichen sclerosus (LS) was first described by Hallopeau in 1887. It is a chronic inflammatory condition most commonly involving the anogenital region with a relapsing course and a potential for destruction, functional impairment, atrophy, and malignant changes. LS affects both sexes with a female preponderance of 5:1. The exact prevalence of the disease is difficult to predict as the lesions are asymptomatic in the initial phase and later when the complications arise patients might visit the surgeon, pediatrician, gynecologist, or urologist. The etiology of LS has a complex interplay of genetic factors, autoimmunity, infections, and trauma. Physical examination to assess the extent of the disease and decide the line of management is the most crucial step in the management. Corticosteroids, calcineurin inhibitor, retinoids, phototherapy, and surgery can be helpful. Self-examination and long-term follow-up are necessary.

Acquired disorders with depigmentation: A systematic approach to vitiliginoid conditions

Acquired disorders with depigmentation are commonly encountered by dermatologists and present with a wide differential diagnosis. Vitiligo, the most common disorder of acquired depigmentation, is characterized by well-defined depigmented macules and patches. Other conditions, such as chemical leukoderma, can present with similar findings, and are often easily mistaken for vitiligo. Key clinical features can help differentiate between acquired disorders of depigmentation. The first article in this continuing medical education series focuses on conditions with a vitiligo-like phenotype. Early recognition and adequate treatment of these conditions is critical in providing appropriate prognostication and treatment.

Diagnostic criteria, severity classification and guidelines of lichen sclerosus et atrophicus

We established diagnostic criteria and severity classification of lichen sclerosus et atrophicus, because there is no established diagnostic criteria or widely accepted severity classification of the disease. Also, there is no clinical guideline for lichen sclerosus et atrophicus in Japan, so we proposed its clinical guideline. The clinical guidelines were formulated by clinical questions and recommendations on the basis of evidence-based medicine according to the New Minds Clinical Practice Guideline Creation Manual (version 1.0). We aimed to make the guidelines easy to use and reliable including the newest evidence, and to present guidance for various clinical problems in treatment of lichen sclerosus et atrophicus.

[Dermato-urology: Male genital lesions urologist should know]

This article aimed to gather male genital dermatoses that may lead to consult a urologist, except pre-neoplastic or neoplastic lesion.

METHOD

This review is based on a research on Pubmed and EM-consult database, in English and in French, using the following key terms "male genital dermatoses", "male genital lesions", "balanitis", "balanoposthitis", "dermatoses des organes génitaux externes masculines", "lésions des organes génitaux externes de l'homme", "balanoposthites".

RESULTS

It highlights normal morphological aspects, acute balanoposthitis (nonspecific, infectious, allergic, irritative and traumatic), common skin disease localized to male genital and male genital specific dermatoses.

CONCLUSION

Any suspicious, fixed, must lead to a skin biopsy.

Penile Inflammatory Skin Disorders and the Preventive Role of Circumcision

Penile inflammatory skin conditions such as balanitis and posthitis are common, especially in uncircumcised males, and feature prominently in medical consultations. We conducted a systematic review of the medical literature on PubMed, EMBASE, and Cohrane databases using keywords "balanitis," "posthitis," "balanoposthitis," "lichen sclerosus," "penile inflammation," and "inflammation penis," along with "circumcision," "circumcised," and "uncircumcised." Balanitis is the most common inflammatory disease of the penis. The accumulation of yeasts and other microorganisms under the foreskin contributes to inflammation of the surrounding penile tissue. The clinical presentation of inflammatory penile conditions includes itching, tenderness, and pain. Penile inflammation is responsible for significant morbidity, including acquired phimosis, balanoposthitis, and lichen sclerosus. Medical treatment can be challenging and a cost burden to the health system. Reducing prevalence is therefore important. While topical antifungal creams can be used, usually accompanied by advice on hygiene, the definitive treatment is circumcision. Data from meta-analyses showed that circumcised males have a 68% lower prevalence of balanitis than uncircumcised males and that balanitis is accompanied by a 3.8-fold increase in risk of penile cancer. Because of the high prevalence and morbidity of penile inflammation, especially in immunocompromised and diabetic patients, circumcision should be more widely adopted globally and is best performed early in infancy.

Review of in situ and invasive penile squamous cell carcinoma and associated non-neoplastic dermatological conditions

Penile carcinoma is a rare genitourinary malignancy in North America and Europe with highest rates recorded in South America, Africa and Asia. Recent classifications have refined the terminology used in classifying intraepithelial/in situ lesions and additionally newer entities have been recognised in the invasive category. While increasing recognition of a bimodal pathway of penile carcinogenesis has facilitated understanding and classification of these tumours, handling and subtyping of penile malignancies presents a challenge to the reporting pathologist, in part due to their rarity. This article reviews the terminology and classification of in situ and invasive carcinomas and their relationship to human papilloma virus status. In addition, associated non-neoplastic dermatological conditions of relevance and appropriate ancillary investigations will be addressed.

[Urological dermatosis]

Urologists are often confronted with venereal and dermatological diseases during clinical evaluation of the external genitals. Dermatosis of the male genitalia ranges from infectious (viral and bacterial) lesions and inflammatory conditions to neoplastic alterations. There are also more general skin diseases (e.g. psoriasis) which occur as genital manifestations. In this case they often show unusual characteristics or the genitalia might be involved only incidentally. This review highlights the clinical diagnosis and therapy of the most common genital skin disorders and demonstrates the medical features.

Fibrosing connective tissue disorders of the skin: molecular similarities and distinctions

A variety of fibrosing connective tissue disorders of the skin have been described. They all share a characteristic activation of fibroblasts resulting in excessive production and deposition of extracellular matrix whereas their etiologies, incidence rates and clinical appearances differ dramatically in part. As effective treatment options are still not on hand, the understanding of cutaneous fibrogenesis needs to be improved. This review focuses on the molecular differences and similarities of the major fibrosing skin disorders namely systemic sclerosis, localized scleroderma, keloid and hypertrophic scars, Eosinophilic fasciitis, Lichen sclerosus and graft-versus-host-disease. Abnormalities in ECM turnover and the impact of matrix-metalloproteases were closely examined. It could be concluded, that besides increased collagen synthesis, modified ECM degradation is an as important factor in cutaneous fibrogenesis. The influence of immune components such as HLA haplotypes and the production of auto-antibodies is crucial for some of the diseases, but not decisive for skin fibrosis in general. A great number of cytokines was reported to be differentially regulated in the respective disorders among whom the components of the gp130/STAT3 signaling pathway seem to be of pivotal importance. Furthermore, the role of miRNAs in the pathogenesis of fibrosing connective tissue diseases of the skin was analyzed according to the current state of knowledge. In summary, this review gives an explicit overview of the various molecular mechanisms leading to fibrosis in the skin and the underlying connective tissue and reveals the most promising targets for future therapeutic approaches.

Diagnosis and treatment of lichen sclerosus: an update

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.

Genital lichen sclerosus/balanitis xerotica obliterans in men with penile carcinoma: a critical analysis

WHAT'S KNOWN ON THE SUBJECT? AND WHAT DOES THE STUDY ADD?: The European Association of Urology guidelines identify lichen sclerosus (LS) as a strong risk factor for penile squamous cell carcinoma (pSCC). However, this statement is based on the findings of case-control studies (Level of Evidence 2a) and a direct causal relationship between LS/balanitis xerotica obliterans (BXO) and pSCC remains to be established. Firm guidelines with respect to the appropriate follow-up policy for LS/BXO are lacking, whereas the impact of synchronous LS/BXO on the prognosis of pSCC remains to be determined. The presence of histologically-confirmed synchronous LS/BXO in patients diagnosed with pSCC is relatively high, although it is not associated with an increased risk of adverse histopathological features. LS/BXO can develop in extragenital skin grafts used for reconstruction after organ-sparing surgery for pSCC.

OBJECTIVES

To determine the rate of lichen sclerosus/balanitis xerotica obliterans (LS/BXO) in patients with penile squamous cell carcinoma (pSCC) and establish whether the presence of LS/BXO is associated with adverse histopathological features of pSCC. To report the phenomenon of LS involving non-genital skin grafts in patients who underwent organ-sparing surgery and split-skin graft (SSG) reconstruction

PATIENTS AND METHODS

Between January 2002 and January 2010, 223 men underwent surgical treatment for pSCC. A group of 52 patients with histologically-confirmed synchronous LS was identified (group A; overall rate of LS/BXO = 23.3%) and compared with a group of patients without synchronous LS (group B; n = 171; 76.7%). A subgroup of patients who underwent surgical excision and SSG reconstruction was also identified The histology reports of graft biopsies obtained during follow-up were reviewed and the rate of LS involving the graft was also recorded.

RESULTS

Mean (range) age at diagnosis was 60.9 (34-81) years and 60.7 (28-89) years for groups A and B, respectively (P = 0.958). The mean (range) duration of follow-up was 38.3 (4-92) months for group A and 45.5 (4-107) months for group B (P = 0.162) No statistically significant differences were noted between groups A and B in terms of tumour grade (P = 0.091), stage (P = 0.697), presence of lymphovascular invasion (P = 0.333), histological subtype (P = 0.107), associated carcinoma in situ (P = 0.246) or nodal status at initial diagnosis (P = 0.555). In the subgroup of 188 patients who underwent SSG reconstruction, 41 (21.8%) patients had histologically-confirmed synchronous LS; in this subgroup, 26 (13.8%) patients underwent graft biopsy during follow-up. Genital LS involving the graft was identified in seven specimens, although none of these seven cases had associated recurrent pSCC.

CONCLUSIONS

The presence of histologically-confirmed synchronous LS in patients with pSCC is relatively high but is not associated with increased rates of adverse histopathological features, including carcinoma in situ. LS can develop in extragenital skin grafts, although its association with the long-term risk for recurrent pSCC is not apparent in the present study.

Development of male genital lichen sclerosus in penile reconstruction skin grafts after cancer surgery: an unreported complication

OBJECTIVE

• To describe the incidence of the development of male genital lichen sclerosus (LS) in non-genital skin grafts used in penile reconstruction after cancer surgery.

PATIENTS AND METHODS

• Between 1997 and 2009, 177 patients received surgical treatment for penile cancer in the Urology Department at Sunderland Royal Hospital, the regional penile cancer centre for the north-east of England. • Patients who had organ-sparing surgery and non-genital penile graft reconstructions were identified. • Histology reports for specimens obtained from those grafts were reviewed to identify the presence of male genital LS and the incidence of recurrence of squamous cell carcinoma (SCC).

RESULTS

• The mean (range) age of patients at diagnosis was 61.8 (32-89) years. Of the 177 patients, 139 had SCC, 32 had carcinoma in situ and six had verrucous carcinoma. • In total, 56 penile reconstructive procedures were performed using split-thickness skin grafts obtained from the inner thigh. • From those grafts, 18 specimens were obtained later for cosmetic, diagnostic or curative purposes. • Male genital LS was found in six of the 18 specimens, and one of them was associated with recurrent verrucous carcinoma.

CONCLUSIONS

• This is the first published series to describe the incidence of male genital LS in penile skin grafts taken from a remote site after penile cancer surgery. • These results represent new information that might help explain the aetiology of male genital LS.

Why circumcision is a biomedical imperative for the 21(st) century

Circumcision of males represents a surgical "vaccine" against a wide variety of infections, adverse medical conditions and potentially fatal diseases over their lifetime, and also protects their sexual partners. In experienced hands, this common, inexpensive procedure is very safe, can be pain-free and can be performed at any age. The benefits vastly outweigh risks. The enormous public health benefits include protection from urinary tract infections, sexually transmitted HIV, HPV, syphilis and chancroid, penile and prostate cancer, phimosis, thrush, and inflammatory dermatoses. In women circumcision of the male partner provides substantial protection from cervical cancer and chlamydia. Circumcision has socio-sexual benefits and reduces sexual problems with age. It has no adverse effect on penile sensitivity, function, or sensation during sexual arousal. Most women prefer the circumcised penis for appearance, hygiene and sex. Given the convincing epidemiological evidence and biological support, routine circumcision should be highly recommended by all health professionals.

RACP's policy statement on infant male circumcision is ill-conceived

OBJECTIVE

To conduct a critical peer-review of the 2004 Policy Statement on routine male circumcision produced by the Royal Australasian College of Physicians (RACP).

METHOD

Comprehensive evaluation in the context of the research field.

RESULTS

We find that the current Statement downplays the wide-ranging life-long benefits of circumcision in prevention of urinary tract infections (UTIs), penile and cervical cancer, genital herpes and chlamydia in women, HIV infection, phimosis, and various penile dermatoses, and at the same time overstates the complication rate. We highlight the many errors in the RACP Statement and note that it sidesteps making a conclusion based on circumcision's well-documented prophylactic health benefits by instead referring to the status of the foreskin at birth. In the era of preventative medicine we view this as irresponsible.

CONCLUSION

The RACP's Statement on routine male circumcision is not evidence-based and should be retracted.

IMPLICATIONS

In the interests of public health and individual well-being an extensive, comprehensive, evidence-based revision should be conducted so as to provide scientifically accurate, balanced information on the advantages, and also the low rate of mostly minor complications, associated with this simple procedure, which for maximum benefits and minimal risk should ideally be performed in the neonatal period.

Is carbon dioxide laser treatment of lichen sclerosus effective in the long run?

OBJECTIVE

To evaluate the long-term results after carbon dioxide laser treatment of lichen sclerosus.

MATERIAL AND METHODS

We evaluated 62 consecutive patients with histologically verified lichen sclerosus admitted between 1985 and 1991. All patients were treated with a carbon dioxide laser with an output of 15-20 W and a defocused beam. This treatment vaporized the macroscopically altered area of the glans penis. Phimosis and superficial meatal stenosis were treated at the same session. Fifty-three men were still alive in 2004, and we were able to contact 50 of them (94%). The patients were asked about recurrence of symptoms, any visible penile lesion and recurrence of meatal stenosis. All patients who reported symptoms were invited to visit the outpatient clinic for further examination.

RESULTS

The median follow-up time was 14 years. At follow-up, 40 patients (80%) had no local symptoms and no visible lesion. Ten patients had minor symptoms but only two required further treatment.

CONCLUSION

Long-term follow-up of carbon dioxide laser treatment of lichen sclerosus shows that the treatment is safe and gives good results.

Is the association between balanitis xerotica obliterans and penile carcinoma underestimated?

OBJECTIVE

To determine the incidence of balanitis xerotica obliterans (BXO) in a consecutive series of penile carcinomas in one centre, as BXO is a common penile disease that usually involves the prepuce and glans, and there have been sporadic case reports of the association between BXO and penile carcinoma, although it is uncertain if there is a specific causal relationship.

PATIENTS AND METHODS

The reported incidence of penile carcinoma in patients with BXO is 2.6-5.8%, leading some to advocate circumcision in all cases, with close follow-up in those with persistent glanular disease. We prospectively analysed all cases of penile cancer referred to the unit over a 54-month period, to determine the prevalence of BXO.

RESULTS

In all, 155 patients with penile malignancy were reviewed, 44 of whom had BXO (28%). This group included 34 men with squamous cell carcinoma and 10 with carcinoma in situ; in 39, BXO and malignancy presented synchronously. In three other cases, cancer occurred in the background of chronic persistent BXO; in two cases penile cancer was truly metachronous. The tumours with associated BXO tended to be of lower stage and grade, and the patients presented when younger, but this was not statistically significant.

CONCLUSION

A significant proportion of patients with penile malignancy have a histological diagnosis of BXO. We think that patients presenting with long-standing BXO and those in whom BXO has not resolved after circumcision warrant biopsies and a careful follow-up.

[Balanitis: diagnosis and treatment]

Balanitis refers to a variety of unrelated conditions. It results from infective, irritative, allergic, traumatic, or inflammatory causes; pre-malignant lesions have been also identified. All these causes are successively reviewed regarding their positive diagnosis and their treatment. Normal aspects of the balanopreputial area will be explained because they may cause some anxiety in certain patients. The difference between the circumcised and uncircumcised penile skin that cause differences in the incidence and appearance of dermatoses of the glans and corona will be studied. Pre-malignant lesions of the balanopreputial area, although not frequent, represent a difficult diagnosis and therapeutic challenge. The major problem is the earliness of the diagnosis that may avoid the occurrence of squamous cell carcinoma. Moreover, lichen sclerosus may develop into squamous cell carcinoma and therefore a lifelong follow-up must be implemented. Thus, any fixed, chronic or suspicious Lesion must be rapidly assessed by a biopsy.

Lichen sclerosus

Lichen sclerosus et atrophicus is a chronic inflammatory disease that mainly affects women in the 5th decade. Although lichen sclerosus most often affects the anogenital region, it may occur in other cutaneous or mucosal sites. Increased fibroblast activity causes cutaneous sclerosis. Recent studies have identified lichen sclerosus as an autoantibody-mediated chronic inflammatory dermatosis. Autoantibodies against the extracellular matrix protein-1 are present in up to 80% of affected patients. In addition to the well-accepted therapy with potent corticosteroids, promising results have been obtained using calcineurin antagonists in the treatment of lichen sclerosus. Interdisciplinary management with regular monitoring can improve the clinical manifestations and quality of life.

Análise clínica e estudo anatomopatológico do prepúcio de pacientes submetidos à postectomia

FUNDAMENTOS E OBJETIVO: Este trabalho tem como objetivo analisar as características histológicas do prepúcio na presença de fimose e a incidência de líquen escleroso (LE) como causa de fimose. MÉTODOS: O Estudo prospectivo incluiu 40 pacientes do sexo masculino com idade entre cinco e 14 anos, com diagnóstico de fimose e indicação cirúrgica como tratamento. Os pacientes - distribuídos em dois grupos em relação ao tempo de doença: fimose primária e secundária - foram submetidos à postectomia no Hospital Infantil Joana de Gusmão, e as peças excisadas, examinadas separadamente por três patologistas. De acordo com as características histopatológicas, os pacientes foram distribuídos em três grupos: achado histológico normal de pele, infiltrado liquenóide e LE. RESULTADOS: As intercorrências clínicas mais freqüentes relatadas pelos pacientes com fimose foram a balanopostite e a infecção do trato urinário (ITU). A maioria deles, 65%, não apresentou alteração histológica da pele; em 22,5% encontrou-se infiltrado liquenóide; e 12,5% dos casos apresentaram alterações próprias de LE. Predominaram os casos de fimose adquirida, representando 57,5% do total. Todos os casos de LE ocorreram nos pacientes com fimose adquirida. A principal indicação cirúrgica desta casuística foi a falência do tratamento clínico (45%), seguida por balanopostite de repetição (25%), estenose grave do prepúcio (17,5%), ITU de repetição (10%) e doença urinária associada (2,5%). CONCLUSÃO: Neste estudo, os autores concluíram que o LE, como causa de fimose, mostrou a incidência de 12,5%.

Guidelines for the management of lichen sclerosus

These guidelines for the management of lichen sclerosus have been prepared for dermatologists on behalf of the British Association of Dermatologists. They present evidence-based guidance for treatment, with identification of the strength of evidence available at the time of preparation of the guidelines, and a brief overview of epidemiological aspects, diagnosis and investigation.

Common skin disorders of the penis

Diseases of the male genitalia range from infectious lesions to inflammatory and neoplastic conditions, including many genital manifestations of more general skin diseases. This review highlights the clinical features, diagnosis and treatment of the most common dermatoses of the male genitalia. Herpes genitalis and infections caused by human papillomavirus (HPV) are increasing, particularly in young sexually active people. Herpes simplex virus infection is the commonest infectious cause of genital ulceration, with evidence that many infections are asymptomatic. HPV infection may be latent, subclinical and clinical. The most common causal agents for condyloma acuminatum are low-risk HPV 6 and 11; high-risk HPV types 16 and 18 are associated with premalignant and malignant lesions. Treatment for genital warts remains unsatisfactory; recurrences are common. Imiquimod, a new topical immunotherapeutic agent, which induces interferon and other cytokines, has the potential to be a first-line therapy for genital warts. Scabies and pediculosis are transmitted by skin-to-skin contact and sexual transmission is common, with the penis and scrotum favourite locations for scabious lesions. Oral ivermectin, a highly active antiparasitic drug, is likely to be the treatment of choice, but until approval is granted it should be reserved for special forms of scabies. Common skin diseases, e.g. psoriasis and lichen planus, may have an atypical appearance in the genital area. The typical psoriatic scale is usually not apparent because of moisture and maceration. Allergic contact dermatitis of the genital area may result from condoms, lubricants, feminine hygiene deodorant spray and spermicides. More often, contact dermatitis is irritant, resulting from persistent moisture and maceration. Lichen sclerosus is a chronic inflammatory disease that occurs as atrophic white patches on the glans penis and foreskin. The penile form is a common cause of phimosis in uncircumcised men; involvement of the urethral meatus may lead to progressive meatal stenosis. Plasma cell balanitis is a benign, idiopathic condition presenting as a solitary, smooth, shiny, red-orange plaque of the glans and prepuce of a middle-aged to older man. Squamous cell carcinoma (SCC) in situ, e.g. erythroplasia of Queyrat and Bowen's disease, cannot be excluded clinically; their apparent clinical benignity may lead to lengthy periods of misdiagnosis and biopsy is required to confirm the diagnosis. SCC is the most common malignancy of the penis and the role of oncogenic HPV-types has been also established in SCC of the penis. Prevention of SCC of the penis presupposes an identification of risk factors, early detection of all pre-cancerous lesions and treatment of phimosis.
