Aim: To characterize the age and pattern of Pap smear abnormalities in a major teaching hospital in Southwestern Nigeria. Design: This is a review of medical records of patients that came for cervical cancer screening. Materials and Methods: The Pap smear results of women between May 2013 and April 2015 were retrieved. A total of 2048 Pap smear results were retrieved during the study period and analyzed with Statistical Package for Social Sciences (SPSS) version 20. A total of 252 (12.3%) samples were excluded from the analysis. Results: The mean age of the women was 45.77 ± 9.9 years and the mode was 50 years. Normal Pap smear result was reported in 728 (40.6%) women. Only 20 women has had more than one more than one Pap smear done. The most common abnormality was inflammatory smear result as this was reported in 613 (29.9%) women. Atypical squamous cell of undetermined significance, low-grade squamous intraepithelial lesion (LGSIL), and high-grade squamous intraepithelial lesion (HGSIL) were reported in 117 (5.7%), 209 (10.2%), and 111 (5.4%) women, respectively. Atypical glandular cell and squamous cell carcinoma were reported in 12 (6.0%) and 3 (1.0%), respectively. Conclusion: There is a high incidence of abnormal Pap smear in this environment and women start cervical cancer screening late in their reproductive life, past the age at which cervical premalignant lesions peak. This may be a contributing factor to the high burden of cervical cancer in developing countries.
