title: [Colposcopy in dysplasia, carcinoma in situ and microinvasive cancer of the cervix--systematic diagnosis].
abstract: Recently colposcopy has come to be increasing used in the diagnosis of the early cervical cancer. We studied colposcopic findings (epithelial, vascular and glandular findings) of dysplasia, carcinoma in situ and microinvasive cancer of the uterine cervix. The results were as follows. We could classify the cases without white epithelium into microinvasive cancer and carcinoma in situ according to elevation or hollowness and roughness and the cases with I grade white epithelium (thin white epithelium) into severe dysplasia and mild or moderate dysplasia according to the existence of elevation, roughness, II type vessels and elevation of gland opening. Among the cases with II grade white epithelium (thick white epithelium) those without roughness, II type vessels and increased gland opening were mild or moderate dysplasia and most case with III or IV type vessels were microinvasive cancer. We concluded that more than half of the cases without III or IV type vessels spread to transverse pollution of white epithelium and lack or indefiniteness of gland opening, severe dysplasia with 0 finding, carcinoma in situ with 1 or 2 finding and microinvasive cancer with 3 findings. With these criteria, we were able to obtain high (93.4% with mean) correct diagnostic ratios.
