Background and Objectives: Anogenital warts frequently recur following ablative treatment, and in the female, has been attributed to the presence of latent HPV infection outside the treatment margins. Goal of this Study: To determine whether HPV DNA sequences were detected by PCR in histologically normal penile skin adjacent to penile warts and to correlate recurrence of warts following surgical ablation to the presence of HPV DNA in histologically normal penile skin. Study Design: Prospective cohort study of 25 heterosexual men with penile warts. Biopsies of clinically healthy penile skin 1 cm from the nearest penile lesion (wart with/without surrounding acetowhite changes) were processed for histology and HPV DNA analysis. The penile wart was processed for HPV DNA analysis only. Recurrence of penile warts was correlated to HPV status of adjacent histologically normal penile skin using Fisher's exact test (FET). Results: Sequences homologous to HPV DNA were detected m 77% of biopsies of histologically normal penile skin. Agreement in HPV DNA type between penile wart and the adjacent histologically normal penile skin was only 30%. Recurrence of warts was noted in 46% of men by 16 weeks, and was not predicted by the detection of HPV DNA in the adjacent histologically normal penile skin (P = 0.16, FET). Conclusions: These findings suggest that extending the treatment margins 1 cm beyond the visible lesion is ineffective in eradicating the virus and preventing recurrence of warts.
