title: [Colposcopic findings of cervical intra-epithelial neoplasia (CIN) and microinvasive carcinoma (Ia) of the uterine cervix--a study of 123 cases].
abstract: From Nov. 1977 to Dec. 1982, 2678 cases of cervical lesions were examined by colposcopy. The colposcopic findings in 95 cases of CIN and 28 cases of Ia of the uterine cervix with histological confirmation were analyzed. The most frequently observed abnormal colposcopic findings are punctated blood vessels, mosaics and white rings around the gland openings. The presence of acetic white epithelium, leukoplakia and atrophic changes is not uncommon. Atypical blood vessel, suggestive invasive process was present in 14.3% of Ia and 4.1% of CIN, but was never observed in dysplasia. The coincidence rate between the colposcopic findings and the histologic diagnosis as assessed by the incidence of abnormal features; extent of lesion; degree of white coloration in the epithelium; the surface contour; the clarity of the margin and the presence of coarse and rising terminal vasculature, was 89%. A typical image, high incidence of abnormal features, extensive lesion, thick and white coloration in the epithelium and irregular surface contour often suggest a severe disease condition. Relation between the colposcopic features and histopathology and ways of improving the conjecture of coincidence rate between them are discussed.
