[Analytical diagnosis in colposcopy by subdivision of abnormal findings]

Abnormal findings of Colposcopy (Colp) were classified in contrast with histology. Varieties of colposcopic abnormal findings appear in more advanced changes in cervical diseases; single in squamous metaplasia, dysplasia and some Ca in situ, double in Ca in situ and microinvasive Ca, triple microinvasive and advanced carcinoma. Atypical vessels are frequently encountered in invasive carcinoma. Circular extension of abnormal figures around external os indicated the following correlation: Within 1/4-2/4 in dysplasia, 2/4-3/4 in Ca in situ and microinvasive Ca, 3/4-4/4 in microinvasive and invasive Ca. In squamous metaplasia and dysplasia, the white epithelia were flat on the surface, comparatively clear in the white part and less elevated. On the other hand, in carcinoma in situ, corresponding to the pathological area, they were rough on the surface, unclear in the white part and highly elevated. Compared with squamous metaplasia and dysplasia, carcinoma in situ in punctation revealed more surface elevation and unclear white part. Characteristic histological figures are dot types in the metaplasia and dysplasia, nest-like types in the carcinoma in situ and atypical vessel transition types in the microinvasive carcinoma. Complete types of mosaic were observed more in metaplasia, slight dysplasia and carcinoma in situ, while the incomplete types were common in moderate and severe dysplasia. Microinvasive carcinoma mosaic revealed more incomplete types and atypical vessel transition types. As for surface elevation and unclear white part, the same tendency was noticed as in punctation and white epithelium.(ABSTRACT TRUNCATED AT 250 WORDS)
