Abstract
ZusammenfassungDie Balanitis plasmacellularis Zoon (BPZ), zuerst beschrieben von J. J. Zoon, ist eine chronische entzündliche Dermatose, die histologisch definiert ist anhand eines subepithelialen, lymphohistiozytären Infiltrates mit vielen Plasmazellen. Dabei wurden ein Spektrum epithelialer Veränderungen und eine variable Zusammensetzung des Infiltrates beschrieben. Dadurch unterscheidet sie sich von der Erythroplasie Queyrat, obwohl beide klinisch sehr ähnlich sind. An der BPZ erkranken vorwiegend ältere, nicht zirkumzidierte, heterosexuelle Männer. Klinisch typisch sind scharf umschriebene, rötlich-glänzende Rundherde an der Dorsalseite der Glans mit Übergang auf den Sulcus und das innere Präputialblatt. Erosionen und flache Infiltrate können hinzukommen. Der Verlauf ist chronisch mit sehr geringen Beschwerden, etwas erhöhte Empfindlichkeit wird oft genannt. Die Pathogenese ist unklar. Barrierestörung und Infektionen, unterhalten durch Feuchtigkeit, Mangel an Hygiene, Traumata und Irritationen, werden diskutiert. Dafür spricht auch das spontane Abheilen nach Zirkumzision oder lokalen Therapien mit Mucipirocin oder Fusidinsäure. Lokale Steroide sind ebenfalls – wie in unserem Fall – effektiv. Eine proaktive Therapie mit Tacrolimus-Salbe scheint eine Option. Die plasmazelluläre Entzündung ist nicht auf das männliche Genitale beschränkt, auch eine Vulvitis plasmacellularis ist beschrieben sowie der Befall nahezu aller weiteren Schleimhäute.

Abstract
The spectrum of conditions affecting the penile skin is varied and ranges from simple, benign dermatoses to premalignant and malignant conditions. Anogenital malignancies and premalignancies are an important personal/public health problem due to their effects on individuals' physical, mental, and sexual health. Furthermore, due to their etiological association with human papillomavirus infection, anogenital malignancies, and premalignancies constitute an immense public health burden. Bowen's disease, Bowenoid papulosis, and erythroplasia of Queyrat are the most widely seen premalignancies of anogenital region and are all forms of squamous intraepithelial neoplasia. Histopathologically, these conditions share identical histologic features of squamous cell carcinoma in situ, but their clinical features differ. In this article, we explore the common precancerous states that can lead to penile carcinoma.

Abstract
In addition to practitioners who care for male patients, with the increased use of high-resolution anoscopy, practitioners who care for women are seeing more men in their practices as well. Some diseases affecting the penis can impact on their sexual partners. Many of the lesions and neoplasms of the penis occur on the vulva as well. In addition, there are common and rare lesions unique to the penis. A review of the scope of penile lesions and neoplasms that may present in a primary care setting is presented to assist in developing a differential diagnosis if such a patient is encountered, as well as for practitioners who care for their sexual partners. A familiarity will assist with recognition, as well as when consultation is needed.

Abstract
Background: Plasma cell balanitis or Zoon's balanitis is an idiopathic benign condition of the genitalia that mostly presents as a solitary, persistent plaque on the glans primarily in uncircumcised, middle-aged to older men. Methods: One hundred twelve patients with a clinical diagnosis of plasma cell balanitis were studied between January 1985 and April 2003. Results: The age of the patients ranged from 24 to 70 years. The majority of patients had symptoms for more than 12 months. Lesions involved the prepuce and glans in the majority of patients (66; 58.92%), the prepuce only in 26 patients (23.21%), and the glans only in 20 patients (17.85%). Tissue for histopathology was available in 96 patients. Histologically, epidermal edema, a dense upper dermal band of chronic inflammatory cells, including many plasma cells, dilated capillaries, extravasated red blood cells, and hemosiderin deposition, was seen. In most, cases, plasma cell balanitis was successfully treated by circumcision. Conclusions: This report describes our experience with plasma cell balanitis and reviews its clinical and histopathologic aspects. The treatment modalities are also reviewed, and the importance of circumcision as the treatment of choice is emphasized.

Abstract
Zoon's balanitis (ZB) is an idiopathic chronic condition usually presenting as a solitary erythematous plaque on the glans of primarily uncircumcised, middle-aged to older men. The different treatment options for this condition often achieve partial results, with frequent recurrence after treatment withdrawal. Recently, photodynamic therapy (PDT) has been proposed as therapeutic option with discordant results. We treated a thirty-five year-old man affected by Zoon's balanitis, resistant to conventional treatments, with 3 sessions of topical ALA-PDT at two weeks intervals. At the end of the treatment period notable improvement of clinical features was observed, with almost complete clearance at 3 months' follow-up, high safety profile and absence of durable side-effects.

Abstract
Plasma cell balanitis (PCB), also knows as Zoon balanitis, is a benign asymptomatic but chronic and erosive inflammatory condition of the glans penis and prepuce that generally affects uncircumcised men in later years. Clinical presentation involves a single, shiny, well defined reddish patch. We describe the first case of PCB ever reported in a patient with a previous history of syphilis, and include a review of the current literature. A 57-year-old Hispanic man with a remote history of syphilis presented with a 6-month nonhealing, granulating ulcer of the foreskin and glans penis that had been repeatedly mistaken for syphilis and treated unsuccessfully with circumcision 3 weeks previously. Biopsy of the glans penis demonstrated sections with denuded chronic granulation tissue showing a fibrotic stroma with numerous blood vessels and a mixed inflammatory infiltrate including scattered plasma cells. It is important to differentiate PCB from a syphilitic chancre in a patient presenting with a nonhealing penile lesion. This case report demonstrates that these entities may be seen in the same patient at different times.

Abstract
BACKGROUND The dermatological aspects of male genital lichen sclerosus (MGLSc) have not received much prominence in the literature. Sexual morbidity appears under-appreciated, the role of histology is unclear, the relative places of topical medical treatment and circumcision are not established, the prognosis for sexual function, urinary function and penis cancer is uncertain and the pathogenesis has not been specifically studied although autoimmunity (as in women) and HPV infection have been mooted. OBJECTIVE To illuminate the above by analysing the clinical parameters of a large series of patients with MGLSc. METHODS A total of 329 patients with a clinical diagnosis of MGLSc were identified retrospectively from a dermatology-centred multidisciplinary setting. Their clinical and histopathological features and outcomes have been abstracted from the records and analysed by simple descriptive statistics. RESULTS The collation and analysis of clinical data derived from the largest series of men with MGLSc ever studied from a dermatological perspective has been achieved. These data allow the conclusions below to be drawn. CONCLUSIONS MGLSc is unequivocally a disease of the uncircumcised male; the adult peak is late in the fourth decade; dyspareunia is a common presenting complaint; non-specific histology requires careful interpretation; most men are either cured by topical treatment with ultrapotent steroid (50-60%) or by circumcision (>75%); effective and definitive management appears to abrogate the risk of developing penile squamous cell carcinoma; urinary contact is implicated in the pathogenesis of MGLSc; HPV infection and autoimmunity seem unimportant.

Abstract
Penile verrucous carcinoma is a rare disease and little is known of its aetiology or pathogenesis. In this study we examined cell-cycle proteins expression and correlation with human papillomavirus infection in a series of 15 pure penile verrucous carcinomas from a single centre. Of 148 penile tumours, 15 (10%) were diagnosed as pure verrucous carcinomas. The expression of the cell-cycle-associated proteins p53, p21, RB, p16(INK4A) and Ki67 were examined by immunohistochemistry. Human papillomavirus infection was determined by polymerase chain reaction to identify a wide range of virus types. The expression of p16(INK4A) and Ki67 was significantly lower in verrucous carcinoma than in usual type squamous cell carcinoma, whereas the expression of p53, p21 and RB was not significantly different. p53 showed basal expression in contrast to usual type squamous cell carcinoma. Human papillomavirus infection was present in only 3 out of 13 verrucous carcinomas. Unique low-risk, high-risk and mixed viral infections were observed in each of the three cases. In conclusion, lower levels of p16(INK4A) and Ki67 expressions differentiate penile verrucous carcinoma from usual type squamous cell carcinoma. The low Ki67 index reflects the slow-growing nature of verrucous tumours. The low level of p16(INK4A) expression and human papillomavirus detection suggests that penile verrucous carcinoma pathogenesis is unrelated to human papillomavirus infection and the oncogenes and tumour suppressor genes classically altered by virus infection.

Abstract
Zoon's balanitis or balanitis circumscripta plasmacellularis is a chronic disease of unknown origin. This condition usually manifests in middle-aged or elderly uncircumcised men. Although of unknown etiology, different factors have been reported to be involved in its genesis (local infections, poor hygiene, heat, friction, and constant rubbing). It is generally considered to be a benign condition, and its association with malignancies has been rarely reported. We report the case of an uncircumcised man, who developed clinically and histopathologically evident squamous cell carcinoma of the penis in an area affected by Zoon's balanitis.

Abstract
An 82-year-old man presented with invasive squamous cell carcinoma of the glans penis arising in erythroplasia of Queyrat. He underwent Mohs' micrographic surgery for the invasive carcinoma. Seven weeks later, the residual erythroplasia of Queyrat was treated using photodynamic therapy. Methyl aminolevulinate cream was applied to the glans of the penis under occlusion for 3 hours and then, after local anaesthesia, irradiated with a 630-nm red-light-emitting diode lamp at a dose of 37 J/cm(2) for 8 min. The patient experienced some mild swelling, redness and pain, which subsided over the following 5 days. Eighteen weeks after photodynamic therapy, there had been no recurrence of the lesion, when the patient died from an unrelated cause.

Abstract
UNLABELLED Untimely old, circumcision has elicited more controversy and war of words than any surgical procedure in history. Although previous claims of benefits like curing masturbation, gout, epilepsy, and even insanity were no doubt absurd, important research has shed light on real medical benefits of circumcision. In particular, the procedure has consistently shown to result in the decreased risk of debilitating and costly diseases such as HIV, cervical cancer, and infantile urinary tract infection. Because of advances in the understanding of the anatomy of the foreskin and pain conditioning in infants, prevailing attitudes have changed about anesthesia and analgesia during the procedure. This article objectively summarizes the bulk of significant medical literature over the last century to provide an accurate statement about what we know and what we do not know about neonatal circumcision, including its history, epidemiology, medical benefits, complications, contraindications, techniques, management for pain, and current controversies. TARGET AUDIENCE Obstetricians & Gynecologists, Family Physicians. LEARNING OBJECTIVES After completion of this article, the reader should be able to describe the evolution of circumcision, to list the potential benefits of circumcision, to outline the various neonatal circumcision techniques, and to summarize the data on the use of analgesia for circumcision.

Abstract
BACKGROUND Long-lasting erythematous lesions involving the balanopreputial sac may be clinically difficult to classify, and biopsies may be performed in order to clarify the nature of the disease. However, our previous experience led us to consider several cases as histopathologically unclassifiable. OBJECTIVE To establish the causes of such unsatisfactory findings. METHODS We reviewed 120 balanopreputial sac biopsies performed at the surgical unit of our institute from January 1999 to December 2002 examining also the patients' clinical records. RESULTS We found that a small group of previously unclassified cases showed common clinical and histopathological features. Clinically, all patients were uncircumcised and had long-lasting asymptomatic erythematous plaques on the balanopreputial sac with no erythroplastic or lichenoid features and no correlation with sexual intercourse. Histologically, all specimens showed a thinned and spongiotic epithelium, a band-like infiltrate of lymphocytes and histiocytes with a variable number of plasma cells in the upper part of the chorion and further signs of acute, subacute or chronic inflammation. CONCLUSIONS In our view, these cases fall within a spectrum of inflammatory non-cicatricial disorders, ranging from almost pure lymphohistiocytic forms to forms which fulfil all criteria to be classified as balanitis circumscripta plasmacellularis of Zoon. We propose to classify these cases histologically as inflammatory non-cicatricial balanoposthitis and clinically as idiopathic inflammatory non-cicatricial balanoposthitis.

Abstract
Certain dermatologic lesions may initially present or be more commonly ascribed to the elderly. These disorders encompass a diverse array of etiologically unrelated degenerative, autoimmune, idiopathic, and neoplastic conditions that may dramatically impact the quality of life and produce significant morbidity and mortality. As the population ages, a more complete understanding of the clinical and histopathologic features unique to the geriatric dermatologic patient is essential.

Abstract
BACKGROUND Penile intraepithelial neoplasia (PIN) is the term used to describe erythroplasia of Queyrat (EQ), Bowen's disease (BD) and bowenoid papulosis (BP). These conditions are distinct clinical entities and have different epidemiological and aetiological associations and prognostic implications. OBJECTIVES To describe the presentation and treatment of patients with PIN. METHODS Thirty-five patients presenting with PIN over a 7-year period are described. RESULTS Our observations include: (i) patients with BP are younger than those with EQ or BD and sometimes have a history of immunosuppression; (ii) patients with BP usually have a history or clinical evidence of previous genital human papillomavirus infection; (iii) patients with EQ often have a concurrent penile dermatosis (lichen sclerosus or lichen planus); (iv) patients with PIN are usually uncircumcised; and (v) response to treatment of BP depends on the integrity of the immune system. CONCLUSIONS We recommend vigorous treatment of all patients with PIN, including circumcision. Smoking should be actively discouraged. Patients should have life-long follow-up and partners of patients with BP should be screened for other forms of intraepithelial neoplasia (cervical and anal).

Abstract
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.
