Dense Acetowhite: A High Grade Lesion?

Abstract

T o describe the ability of colposcopy in predicting the high grade squamous intraepithelial lesion (SIL) a retrospective, descriptive study was undertaken from January 1, 1993 until November 30, 1995. Agreement between colposcopy and histology results was described in unweighted Kappa. Agreement between colposcopy diagnosis and histology results taken from the dense acetowhitening areas was poor (Kappa 0.5). This agreement will be higher in areas of acetowhite that has an abrupt peeling margin in 72/74 cases. It seems that dense acetowhite areas showed high grade lesions in most of cases observed especially if they had also abrupt peeling margin.
