Methods: HPV test results were obtained from patient file archives of the Gynecology and Obstetrics Clinic. Pathology report results were obtained from the digital records of the Pathology Laboratory and the patient file archives of the Gynecology and Obstetrics Clinic in 2018. Results: The most frequently detected was HPV16 (29.2%), followed by HPV51 (13.1%), HPV56 (11%), HPV31 (9.2%), HPV52 (8.4%), and HPV68 (8.2%). HPV16 was positive in 50% of patients diagnosed with SCC, 54.9% of patients with HSIL, 27% of patients with LSIL, and 25% of cases diagnosed as benign (P<0.001). HPV18 was positive in 25% of patients diagnosed with SCC, 11% of patients with HSIL, 4.7% of patients with LSIL, and 5.2% of cases diagnosed as benign (P=0.019). Conclusion: The most frequent hrHPV genotype was HPV16, followed by HPV51, HPV 56, and HPV 31. There is an increase in the frequency of HPV51 and HPV56. HPV51, not included in HPV vaccines and is the second most frequent, should be included in these vaccines. In addition, although the frequency of HPV18 has decreased, HSIL and SCC generation is still high together with HPV16. https://ijph.tums.ac.ir/index.php/ijph/article/view/26872 https://ijph.tums.ac.ir/index.php/ijph/article/download/26872/7888
