Penile intra-epithelial neoplasia (PIN) are precancerous lesions, characterized by architectural and cytological abnormalities of the genital epithelium, from which can arise squamous carcinomas.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.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.Urologists should distinguish HPV-related and non HPV-related PIN, both of them sharing clinical presentation, but needing different management.
