[Colposcopic picture of vessels in decidual ectopy (deciduosis) at the portio vaginalis uteri].

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.
