title: Colposcopic differential diagnosis of dysplasia, carcinoma in situ and microinvasive carcinoma of the cervix.
abstract: Two hundred and twenty-eight patients with cervical neoplasia, detected in routine uterine cancer screening at the Center for Adult Diseases, Osaka, from 1973 through 1977 were selected. The histological diagnosis was as follows: dysplasia, 69; carcinoma in situ, 102; and microinvasive carcinoma, 57. A retrospective study of this material was made with the aid of adequate colposcopic colour photographs, and features likely to be useful in differential diagnosis were determined. Atypical vessels were seen in 24 of 36 patients (67%) with Stage Ia1 lesions, but only in a few of those with Stage 02 lesions. Punctation, mosaic and white epithelium were less evident in stage Ia2 than in Stage 01 and Stage 02. Punctation, mosaic and white epithelium in patients with dysplasia were less formed, and their borders were less distinct than in patients with Stage 0 lesions. These characteristic changes are of value in accurate colposcopic diagnosis.
