[Development of ectopia. Colposcopic and colpotopographic studies]

Abstract

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.
