Application of 2011 International Federation for Cervical Pathology and Colposcopy Terminology on the Detection of Vaginal Intraepithelial Neoplasia.

The agreement between colposcopy findings utilizing the 2011 IFCPC terminology and vaginal pathology is moderate, and more definite findings for high-grade VaIN may be needed. The micropapillary pattern can be considered an alternative low-grade finding, while iodine staining is nonspecific for all lesions. Scattered and spotty lesions suggest low-grade VaIN, while large single lesions suggest high-grade VaIN.
