What screen?

  • Endometrial cells in woman >40 yo
  • Epithelial cell abnormalities (atypical SC (ASC-US)), LSIL, HSIL, SCC
  • Glandular cell abnomralities (atypical endocervical cells)
  • Obtain the smear two weeks after the first day of the last menstrual periodo
A
  • PAP smear is gold standard for screening→ scrape away cells from transition zone→ look for dysplasia (high N:C ratio), dark, hyperchromatic nucleus
  • Pap smear is good to detect SCC and precursor lesions
