    Abstract:
    UNLABELLED: The aim of the study was the determination of colposcopic images of the atypical transformation zone and the estimation of their relationship with cervical intraepithelial neoplasia. MATERIAL AND METHODS: 8700 women hospitalized in the Department of Gynaecology and Gynaecologic Oncology of the Municipal Hospital in Kielce between October 1996 and March 2003 were included in this study. In every investigated women the gynaecological examination, PAP smear, vaginal biocenosis, image colposcopy and histological examination were performed. Colposcopic images underwent computer analysis. Patients were divided into two groups. Behind the criterion of the division one accepted the occurrence (group 1) or the lack (the group II) cervical intraepithelial neoplasia in the histological examination. RESULTS: Atypical transformation zone occurred in 3.8% of investigated women. The statistical analysis showed the lack of the correlation between occurrence of flat punctation pattern and negative iodine uptake in women with the atypical transformation zone. Acetowhite epithelium, very white or gray opaque epithelium, flat mosaic, coarse mosaic, flat and coarse leukoplakia, coarse punctation and atypical vessels correlated statistically (p < 0.05) with the atypical transformation zone. CONCLUSIONS: Acetowhite, very white or gray opaque epithelium, coarse punctation, flat mosaic, coarse mosaic, flat and coarse leukoplakia, coarse punctation, atypical vessels are the characteristic colposcopy images of the transformation zone. There is a correlation between acetowhite epithelium and flat leukoplakia and CIN 1. Coarse punctation, coarse mosaic and coarse leukoplakia correlate with the presence of CIN 3. Flat punctation and negative iodine uptake are not characteristic colposcopy images of the atypical transformation zone.
