Summary
Postmenopausal women with atypical squamous cells of undetermined significance (ASCUS) or low-grade squamous intraepithelial lesions (LSIL) require careful evaluation. Squamous-cell abnormalities in this population are significant when artifactual changes are excluded.
Area of Science:
- Gynecologic Cytopathology
- Postmenopausal Health
Background:
- Exfoliative cytology for ASCUS and LSIL is understudied in postmenopausal women.
- This demographic is increasing, necessitating focused research.
Purpose of the Study:
- To reevaluate cytologic findings of ASCUS and LSIL in postmenopausal women.
- To identify diagnostic pitfalls and assess the significance of squamous-cell abnormalities.
Main Methods:
- Retrospective review of 60 cases initially interpreted as ASCUS or LSIL.
- Cytologic reevaluation using uniform diagnostic criteria.
- Analysis of follow-up data including histology and repeat cytology.
Main Results:
- Squamous-cell abnormalities were confirmed in 45 of 60 cases (18 ASCUS, 27 LSIL).
- Fifteen cases were reclassified as benign after applying uniform criteria.
- Follow-up revealed CIN I (5), VAIN I-II (1) in ASCUS cases, and CIN (20), VAIN (1) in LSIL cases.
- Two patients presented with vaginal dysplasia exclusively.
Conclusions:
- Squamous-cell abnormalities in postmenopausal women, including ASCUS and LSIL, can be significant.
- Diagnostic accuracy is improved by eliminating artifactual changes like inflammation and drying.
- Careful cytologic interpretation is crucial for managing these lesions in the postmenopausal population.
