Those which originate in the cervical canal and, therefore, froma surface covered entirely with cylindrical epithelium. According to its origin such a cervical polyp has as a covering squa-mous epithelium or cylindrical epithelium, or both. Corresponding to its epithelial covering, a polyp possesses the stromaof that tissue from which it originates, and represents simply an ex-cessive circumscribed growth of an existing tissue. Just as the elementsnormally present in the originating matrix are here represented, so like-wise may be found in polyps such formations as are frequently foundin the originating base of the polyp, without their being considered as se-rious pathological changes. In the cervix these are, as we have seen,.

Therefore, if a polyp originates from theouter surface of the vaginal portion, it will show a covering of squamousepithelium if the area from which it originated was normal. In addition,it will consist of a stroma containing numerous connective-tissue cells,fibrous connective tissue, and vessels. The latter are especially well de-veloped in the pedicle, so that here all the other tissues are in the back-ground. The increase in the vessels is also present on the surface of apolyp, where turgid capillaries are often found. From this we understand why such polyps bleed easily on touch, andwhy dangerous bleeding after re
