Reactive glandular atypia in cervical tissue can mimic adenocarcinoma but is often benign. This study defines its cytologic features and links it to inflammation, hormonal use, and HPV, showing no progression to cancer.

Area of Science:

  • Gynecologic Pathology
  • Cervical Cytology
  • Surgical Pathology

Background:

  • Reactive glandular atypia in endocervical cells can be challenging to distinguish from adenocarcinoma.
  • Understanding the causes and cytologic features of reactive atypia is crucial for accurate diagnosis.

Purpose of the Study:

  • To define the histologic and cytologic characteristics of reactive glandular atypia in endocervical tissues.
  • To investigate potential associations of reactive atypia with inflammatory, regenerative, hormonal, or viral factors.
  • To assess the clinical significance and follow-up of cases with reactive atypia.

Main Methods:

  • Histologic examination of 1,500 cervical tissue specimens to identify cases with reactive glandular atypia.
  • Review of concurrent cervico-vaginal smears for cytologic correlation.

  • Examination of endocervical polyps and hysterectomy specimens to evaluate reactive changes.
  • Analysis of clinical data, including hormonal usage and follow-up information.

    • Main Results:

    • Twenty-seven cases (1.8%) showed histologic reactive glandular atypia, characterized by enlarged, hyperchromatic, irregular nuclei.
    • Six of 18 reviewed smears showed similar cytologic atypia.
    • Reactive atypia was observed in endocervical polyps and hysterectomy specimens, supporting its reactive nature.
    • Associations were noted with hormonal usage (9/27) and squamous intraepithelial lesions/HPV (14/27).
    • No progression to adenocarcinoma was observed during follow-up of the 27 index cases.

    Conclusions:

    • Endocervical reactive glandular atypia can be distinguished from adenocarcinoma based on defined histologic and cytologic criteria.
    • Inflammatory-regenerative processes, hormonal influences, and possibly human papilloma virus are associated with reactive atypia.
    • Reactive atypia does not appear to be a precursor lesion to endocervical adenocarcinoma.
