Penile intraepithelial neoplasia: important lessons from a case series

Abstract

Summary Seven men presenting to our genitourinary (GU) medicine clinic over a period of 22 months had a histopathological diagnosis of penile intraepithelial neoplasia (PIN). Median duration of symptoms was eight months (range 2–216 months). Macroscopic appearances were different in all cases. All histology was reviewed locally and at a tertiary centre. Six of seven had severe dysplasia (PIN III). Interestingly, only one individual was HIV-positive and one, who was immunocompetent, had multifocal disease. These cases highlight the importance of a full anogenital examination and early biopsy in patients presenting with atypical or persistent penile lesions.
