[On the localisation of the adenocarcinoma in situ of the cervix uteri (author's transl)].

The position and the extent of 42 adenocarcinomas in situ were determined in representative sections of 27 cone specimens. At the same time all foci of a coincidental atypical squamous epithelium were registered. It was found that the glandular cancer arises rather in the canal than at the ectocervix. The topography of an additional pathological squamous epithelium follows the rules described for cases with malignant squamous epithelium only.
