Prevalence of anal squamous intra-epithelial lesion in women presenting genital squamous intra-epithelial lesion.
OBJECTIVE
To determine the frequency of anal squamous intra-epithelial lesions (ASIL) in women with genital squamous intra-epithelial lesions (GSIL).


METHODS
In a cross sectional study, 184 patients with histopathological diagnosis of GSIL and 76 controls without GSIL, were submitted to anuscopy in order to determine the presence of ASIL. All the women were HIV-negative with anal aceto-white lesions were biopsed for histological diagnosis.


RESULTS
The frequency of ASIL was 17.4% in the GSIL group (3.2% high grade ASIL) and only 2.6% in the control group (0% high grade ASIL) (p<0.001). All the high grade ASIL diagnoses were found in women with cervical SIL.


CONCLUSIONS
Women presenting GSIL have high prevalence of ASIL.
