[Penile intraepithelial neoplasia]

Penile carcinogenesis can be superposed on vulvar carcinogenesis, with two pathways : with or without a link to HPV. Penile squamous cell carcinomas arise from precursor lesions: penile intraepithelial neoplasia (PeIN) defined by the presence of intraepithelial atypia, which can progress to invasive squamous cell carcinoma. Differentiated PeINs not linked to HPV, affect elderly men with inflammatory lesions, most often lichen sclerosus. PeINs linked to HPV, basaloid, condylomatous or condylomatous-basaloid growth affect younger men. Although clinically similar, their distinction is important, because the treatment differs with a greater risk of invasion for forms unrelated to HPV.

[Carbon dioxide laser treatment of genital intraepithelial neoplasia: A retrospective study]

INTRODUCTION

Genital intraepithelial neoplasias (IEN) are precursors of squamous cell carcinoma. The ideal treatment must be efficacious, conservative and well-tolerated. CO2 laser is one of the recommended therapies, but its efficacy and safety have not been extensively studied.

PATIENTS AND METHODS

This was a retrospective single-center study. Sixteen patients (8 women and 8 men) treated with CO2 laser for genital IEN, whether high-grade or differentiated, were included. Surgical lateral margins of 3 to 5mm were taken macroscopically during treatment. The CO2 laser session, assessment of therapeutic response and follow-up were undertaken by a dermatologist at the University Hospital of Caen.

RESULTS

The mean patient age was 68.1 years and mean follow-up was 52.7 months (5-130). Lesions were isolated in 87.5% of patients. The recurrence rates of genital intraepithelial neoplasia after CO2 laser treatment were 58% for women and 40% for men. No impact on quality of life or on sexual activity was reported in over 90% of patients.

CONCLUSION

Whatever the treatment recommended for intraepithelial neoplasia, recurrence is frequent. CO2 laser is an effective and well-tolerated conservative therapeutic option. It enables rapid clinical remission, but as with all currently available treatments, long-term dermatologic follow-up remains necessary.

Review of cutaneous penile lesions

Introduction:

Penile lesions often go undiagnosed and are difficult to identify for general practitioners and specialists, yet the stakes could be high. Indeed, the condition is highly varied and includes physiological variants, specific skin entities, genital dermatoses, genital ulcers, balanitis, premalignant lesions, and, finally, cancerous lesions. Knowledge of these entities can help to prevent overlooking potentially progressive lesions and diagnose cancerous lesions early so that patients can be offered conservative treatment, improving chances of survival. We review here these different lesions.

Materials and methods and authors personal experience:

A literature review was carried out in December 2016 using the Medline/Pubmed database, without any restrictions regarding the time period but limiting the review to studies in English or French. The main keywords used were “penile lesion”, “penile cancer”, “balanitis” and “premalignant lesion”. A specific review was performed for each type. All the pictures and cases came from our personal practice in our specific uro-dermatological consultation. All the patients gave us their informed consent for the utilization of their pictures.

Results:

We studied 66 references covering the field of benign and malignant lesions and their respective treatment. It is essential to take a medical history and perform a clinical examination, despite the fact that some lesions are not specific. A biopsy must be performed systematically in the case of all suspicious lesions.

Conclusion:

Lesions on genital organs in men are very diverse. Some are difficult to diagnose and treat, with the main challenge being early diagnosis of lesions with a high progressive potential in order to prevent dissemination and the need for mutilating surgery.

[Penile intra-epithelial neoplasia]

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 ». 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.
