Definition / general
  • 2 - 5% of adult women
  • Usually multigravida age 30 - 59 years
  • Produces bleeding or mucoid discharge
  • Probably secondary to chronic inflammation and not neoplastic
Clinical features
  • Endocervical polyps originate in the endocervical canal in 2 - 5% of women
  • May be benign or contain another lesions such as dysplasia or carcinoma
  • Benign polyps may be diagnosed as AGUS on cytologic smear (Acta Cytol 2000;44:41, Acta Cytol 1999;43:351)

Microscopic (histologic) description
  • Dilated endocervical (mucus) glands in inflamed, myxoid stroma
  • Papillary endocervicitis if branching papillary structure

Cytology description
  • Tridimensional groups of endocervical cells, may show squamous metaplasia, hyperchromasia, mitosis and cellular crowding limited to a few groups of cells only
  • Endocervical polyps are prone to ulceration that causes degenerative, reparative and metaplastic changes that can be seen on cytology; these changes may mimic dysplasia or glandular neoplasia
  • Benign polyps have no feathering, no nuclear palisading, no chromatin clearing
  • Rarely contains metastatic disease (Acta Cytol 1996;40:765)
