    Abstract:
    133 patients attending the colposcopy-laser outpatient consultations were examined simultaneously by cytology, colposcopy and punch biopsy. A cone biopsy was taken 25 patients and one patient was hysterectomised later. A comparison between cytology and histology revealed 17.1% false negative smear results. Cytology and histology showed the same result in 84.6%. The highest percentage of high-grade dysplasia was found in colposcopy with signs of punctation and/or mosaicism. A similar diagnosis was achieved in 92.3% of cases comparing punch with cone biopsy. Simultaneous use of cytology, colposcopy and punch biopsy enables reliable diagnosis and follow-up of dysplastic lesions of the cervix. Besides, one can use punch biopsy as basic histology for local destructive manoeuvres such as laser vaporisation.
