Objective:
To evaluate women with postcoital bleeding (PCB) by clinical examination, cytology, colposcopy, and histopathology.
Methods:
A cross-sectional study of 123 women with PCB, who were referred to the Colposcopy Clinic of Arash Hospital, Tehran, over a 2-year period.
Results:
Clinical examinations revealed cervical polyps in 18 women and ectropion in 14. Cervical cytology identified 13 patients with atypical squamous cells of undetermined significance, 2 with atypical glandular cells, 4 with low-grade squamous intraepithelial lesions, and 3 with high-grade squamous intraepithelial lesions. Colposcopy indicated invasive cancer in 1 patient. Transitional zones appeared normal in 39.8% of the cohort, were atypical grade 1 in 33.3%, and atypical grade 2 in 4.9%. Fourteen abnormalities were detected at histology, including 1 squamous cell carcinoma, 1 low-grade glandular neoplasm, 9 cervical intraepithelial neoplasia (CIN) grade 1, 2 CIN grade 2, and 1 CIN grade 3. The sensitivity and specificity of cytology were 50% and 86.5%, respectively. A total of 21.4% of abnormal pathologies were missed using colposcopy, which had a sensitivity of 79%.
Conclusion:
Because of its higher sensitivity, colposcopy can be recommended for the investigation of persistent PCB, even in the presence of normal cytology.
