SummaryBackground 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).
