A case of carcinoma in situ with the beginning of invasion is presented. In contradistinction to the changes characteristic of such cases, in this case branching vessels completely typical of a normal transformation zone were found. This suggests only adaptive vascular hypertrophy without vascular neoplasia, in spite of the cancerous changes in the epithelium in situ.

The types of bloodvessel visible on colposcopic examination in various forms of decidual ectopia are described. The two main tapes are linear-spiral vessels and "asymmetrical loops". The possible differentiation, on the basis of the vascular picture of decidual from malignant changes in the cervix uteri by colposcopy is pointed out stressed. The functional state of the bloodvessels, probably newly-formed during the proliferation of the decidually transformed epithelial stroma, is briefly discussed.

On the basis of colposcopical observations a possible, though certainly rare, mode of development of ectopia is described. Proliferation of the glands of the upper part of the cervical canal up to the base of the squamous epithelium leads to exfoliation and desquamation of this and to extension of the columnar epithelium on the surface of the vaginal portio. The possible causes of this process are briefly presented.
