What is bowenoid papulosis?

Bowenoid papulosis is a sexually transmitted infection that presents as pigmented genital papules due to human papillomavirus (HPV) infection with histology closely resembling squamous cell carcinoma-in-situ (Bowen disease). It is now classified as a vulval or penile high-grade squamous intraepithelial lesion (HSIL) and 'bowenoid papulosis' is no longer used by pathologists in the WHO Classification of Tumours, 2020 5th edition.
