Epidermolytic acanthoma (EA) is a rare benign tumor, which usually appears as a solitary small papule. However, there are a few case reports of multiple EA, most of which occurs on the genital area. Cases of multiple EA may mimic verruca vulgaris, condyloma accuminatum, seborrheic keratosis, and bowenoid papulosis, and therefore, can be easily misdiagnosed. Read More

Bowenoid papulosis is an uncommon precancerous condition of the genitalia caused by oncogenic human papillomavirus types. It is seen in young, sexually active adults and histologically resembles Bowen's disease. Dermoscopy is useful in the diagnosis of both pigmented and non-pigmented skin lesions, but dermoscopic diagnostic accuracy criteria have not yet developed in diseases such as bowenoid papulosis and Bowen's disease.

Background: Genital skin malignancies are a rare entity encountered by clinicians that may result in significant morbidity and mortality. Lack of familiarity or expertise in this area among clinicians can delay appropriate management of these conditions and may result in disease progression.

Methods: We performed a retrospective descriptive cohort study of male patients who received a genital skin biopsy reported by one major dermatopathology laboratory between January 2017 and December 2018 with a histological diagnosis of a premalignant or malignant condition. Read More

Vulvar carcinomas represent 4% of all gynaecological cancers with 838 new cases in France in 2018. The precursor lesions of vulvar carcinomas are differentiated vulvar intraepithelial lesion (dVIN) in a context of lichen sclerosus and vulvar high-grade squamous intraepithelial lesion (HSIL) link to human papillomavirus (HPV) infection. Three typical clinical forms of HSIL are described: the Bowenoid papulosis, the Bowen's disease and the confluent VIN. Read More

Introduction: Penile intraepithelial neoplasia (PeIN) is a histological term for precancerous penile lesions. PeIN is important due to the high morbidity and mortality associated with progression to penile squamous cell carcinoma (PSSC). But PeIN is rare, contributing to a limited evidence-base for the relative efficacy of available treatment options. Read More

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. Read More

Polyphenon E 10%, a green tea extract containing epigallocatechin gallate (EGCG) as the main active compound, is a topical formulation indicated for the treatment of genital warts. Polyphenon E has also shown to be very effective in the treatment of periungual and plane warts. Here, we report a dramatic clinical effect of topical treatment with polyphenon E in a subject with multiple "seborrheic keratosis-like" lesions of the genital area. Read More
