ABSTRACT
Objectives:
To compare morphological abnormalities on anal colposcopy against histology to determine anal high-grade squamous intraepithelial lesions (HSILs).Methods:
This is a retrospective data assessment of HIV-negative and HIV-positive patients undergoing outpatient follow-up. The sample comprised 54 patients presenting acetowhite lesions on anal colposcopy. Acetowhite lesions were classified according to their morphology into punctation, verrucous, mosaic, ulcerated, or hypervascularized, and biopsies of these specimens were classified as anal HSIL, low-grade squamous intraepithelial lesion (LSIL), or normal. The data were analyzed using SPSS forWindows version 13.0 (SPSS Inc., Chicago, IL, USA). The results were analyzed using the nonparametric Mann-Whitney test, the Fisher exact test and the chi-squared parametric test. A 95% confidence interval (CI) was used and a level of significance <5% was adopted for all statistical tests. Results Fifty-four patients (50 males, 80% HIV+) with biopsied acetowhite lesions were assessed. There were 31 punctation lesions, 1 classified as HSIL (3.2%; 95%CI 0- 40.0), 17 verrucous lesions, 3 HSIL (17.7%; 95%CI 0-10.7), and 1 ulcerated, classified as HSIL (100%), and 4 mosaic and 1 atypical vessel lesion, all classified as LSIL. The results showed no association of presence of anal HSIL with positivity for HIV infection or with counts above or below 500/µl in HIV+patients. Statistical analysis was performed using the Mann-Whitney nonparametric test, the Fisher exact test, and the chi-squared parametric test.Conclusion:
The comparison of morphological findings on anal colposcopy against histology revealed no morphological pattern suggesting anal HSIL. (AU)
