  • The 2001 Bethesda System terminology is used for cytologic classification (for example, LSIL and HSIL).
  • A two-tiered grading for histologic classification is used for precursor lesions: CIN1 and CIN2,3.
  • CIN in endocervical curettings should be graded, if possible—that is, CIN1 versus CIN2,3.
  • CIN1 should be followed without treatment—for up to two years. o In adolescents, separate CIN2 and CIN3, if possible—management differs.
  • A histologic diagnosis of CIN2 in the adolescent should be initially followed conservatively.
