[Pathology of early cancer of the uterus].

Early cancer of the uterine cervix is comprised of in situ (intraepithelial) and microinvasive malignancies both in squamous cell carcinoma and adenocarcinoma. The general concept of these conditions as well as histologic criteria was mentioned. The differential diagnosis on histology between early cancer and their related lesions was also described. As to endometrial adenocarcinoma, it is impossible to separate in situ adenocarcinoma from atypical endometrial hyperplasia. Therefore, in situ adenocarcinoma of the endometrium is theoretically accepted, but practically should be avoided.
