Clinical Information
  • A precancerous neoplastic process that affects the cervical epithelium without evidence of invasion. It is usually associated with human papillomavirus infection. It is characterized by the presence of mild atypia in the superficial epithelial layer that may be associated with koilocytosis. Maturation is present in the upper two thirds of the epithelium. Mitotic figures are not numerous and are present in the basal third of the epithelium.
