This is the condition often described as placentalpolyp and as polypoid hematomata of the uterus. Polypoid Endometritis.—Instead of being evenly and generallythickened, the decidua may display at certain points a less pro-nounced hypertrophy, or, on the other hand, upon the uterinesurface maybe seen projections or excrescences where the hyper-plastic process seems to have been exaggerated over a limitedarea. Such cases have been described by 1 [ofe and is, however, to the most advanced type of this polypoid condi-tion of the uterine mucous membrane that Virchow * first gavethe name of endometritis decidua polyposa or Fig. 114.—Polypoid endometritis : a, Fine apertures of the glands ; b,b, larger aper-tures of the glands; r,r, protuberances or polypi. In these cases the internal surface of the decidua presents amost peculiar appearance. Villus-like projections stand out fromthe degenerated mucous membrane to the height of half an inchor more, smooth of surface and very vascular. In the intervalsbetween the projections may be seen the openings of the uterineglands, which are not to be found on tin- polypoid whole membrane is greatly thickened, which, as a micro-scopic examination shows, is due to the great hypertrophy of theconnective-tissue elements and to a great increase in the decidual 1 I).
