In men, human papillomavirus (HPV) infection can cause two different types of external genital lesions: condylomata (genital warts) and penile intraepithelial neoplasia (PeIN). A new study provides clinical and molecular data on the progression of HPV infection to condylomata and PeIN, as well as virus genotype information that might be useful for vaccine preparation.
