Ms. Ang et al., COLPOSCOPICALLY DIRECTED BIOPSY AND LOOP EXCISION OF THE TRANSFORMATION ZONE - COMPARISON OF HISTOLOGIC-FINDINGS, Journal of reproductive medicine, 40(3), 1995, pp. 167-170
We performed a retrospective comparison between the findings from colp
oscopically directed biopsies and those from loop excision of the tran
sformation zone (LETZ) specimens. The correlation was satisfactory. Wh
en a low grade squamous intraepithelial lesion (SIL) was predicted on
a cytologic smear and biopsy specimen, no cases of invasive carcinoma
were found. In two (0.8%) cases in which a high grade SIL was predicte
d on the cervical smear and biopsy, microinvasive carcinoma was found
in the LETZ specimen.
