title: Colposcopy of intraepithelial neoplasia of the vulva and adjacent sites.
abstract: The colposcopic appearances of VIN III differ on the vulva and adjacent sites according to the anatomic sites. Lesions on the hairy skin appear more well defined than lesions on nonhairy areas. VIN III histologically can extend into underlying adnexal structures. Most frequently, it is the hair follicles in which it may extend deeply. This involvement is not identified by colposcopic methods. A variety of colposcopic mimics or "look-alike" lesions occur on the vulvar skin. Therefore the performance of a biopsy is required to establish the diagnosis.
