Cervical intraepithelial neoplasia (CIN). Comparison of histological and Pap results. Objectives: The aim of this study is to examine the compatibility of pathohistological and Pap findings on material obtained by biopsy of the cervix and excohleation and examine the compatibility of quality histological pattern and diagnosis. Study design: The study is structured as a cross-sectional study of 152 subjects with premalignant lesions. Material and methodes: The study involved 152 patients with premalignant lesions in the cervix which has made a Pap test and targeted biopsy of the cervix. From the available medical records were collected archival data on Pap test and histological diagnosis. Information on age and advisable clinical diagnoses was obtained from referrals for pathohistological examination of tissue. The age of the subjects was determined at the time when tissue samples were taken for analysis. Data on the quality of materials are obtained on the basis of microscopic evaluation of the collected material. Results: The largest number of patients has cytological (57,2 %) and pathohistological (55,2 %) diagnosis of cervical intraepithelial neoplasia type 3 (CIN 3). The largest percentage of the treated material was assessed as very good (46,1 %). The majority of respondents (92,4 %) has no difference in the diagnosis set on the basis of the Pap test and pathohistological analysis. There was no statistically significant difference in the diagnosis set on the basis of the Pap test and pathohistological analysis depending on the quality of materials. Conclusion: There was a strong positive correlation between grade established on cytology (Pap test) and pathohistological diagnosis (PHD). There was no statistically significant difference in the diagnosis set on the basis of the Pap test and pathohistological analysis depending on the quality of materials.
