Often, too, there is extensive calcareous degeneration. The consequence of syphilitic disease of the placenta isusually disastrous to the fetus and often dangerous to the cellular infiltration of the villi obliterates the blood-vesselswithin them, and consequently abrogates their functions. Thesame effect may be produced by the hyperplasia of the deciduaserotina and the consequent encroachment of the decidual tissueupon the intervillous blood-spaces, or the destruction of the villimay be brought about by the formation of the nodular massesthat have been noticed. All these processes, if, as is the rule, 1 Charpentier, Syph. hereditaire, 1870, Presse Med.

The endometritis placentaris that is often aprominent feature of placental syphilis may prove dangerousto the mother by so matting the layers of the decidua serotinatogether as to occasion a close adherence of the placenta to theuterine wall, thus subjecting the woman to the perils of hemor-rhage, septicemia, or inversion of the uterus that are incidentalto adherent placentae. The accurate diagnosis of placental syphilis is impossibleduring pregnancy. The condition may be inferred with con-siderable certainty, however, should a history of syphilitic infec-tion be obtained from either parent. The treatment will be referred to later under the head ofFetal Syphilis.
