Prevalence of anal cytological abnormalities in women with positive cervical cytology.

The objective of this study was to estimate the prevalence of cytological abnormalities of the anal mucosa in women with positive cervical cytology, but without macroscopic anal lesion. Ultimately we postulated if the anal mucosa may be a reservoir of HPV, which would allow the reinfection of cervix. Forty-nine patients with abnormal cervical cytology were selected for this work.
