The presence of the l)'nipho- cytes in the tissue obscures many of the decidual cells. berg’s first case is of interest in that there were several polyps the size of a bean in the lower cervix, yet the marked ha'inorrhage may well have come from the jilacenta prtevia. Yet it would ap])car that the htemorrhage in his second case (post-abortum) arose from abra- sions in the decidual area. The treatment adopted by Stroganoff could not well have been attempted in my case, even had I been aware of Ins hajipy result. The denudation of the entire cer- vical cavity would jiresent too many risks, even though it were proven that the growth was benign. Thus far no one theory has sufficed to ex- plain the presence of decidual tissue in all its various sites. It is doubtless true that a distinct and continuous membrane is limited to the uterus, yet the ectopic decidua which arises in connection with jiregnancy cannot well be distinguished from similar areas of the compact zone of the decidua vera. And until a better test arises to determine what is and what is not decidua, we must continue to take the cell as our guide, bad guide though it be, provided the diagnosis is controlled by the study of wide enough areas and sufficient sec- tions. Cervical decidua associated with placenta prievia may be extension from above down- ward, if the histological os grows in size dur- ing the formation of the lower uterine seg- ment, as suggested by Bayer; yet a vascular cervix is described in the cases of the literature as a common feature to all. It may be that cervical tissue does not always arise from the stimulus of pregnancy alone, and the irritant of inflammation may commonly be necessary. Certain it is, however, that malignant tumors, circumscribtal inflammations, erosions, polyj)s, etc., are re})orfed most freciuently with de- cidua in this unusual site. FiK- 3. Decidual cells may be seen on the side of the small blood-vessel, apparently arising from the perithclial layer.](https://iiif.wellcomecollection.org/image/b22466678_0011.jp2/full/800%2C/0/default.jpg)
