Plate 15

An ovum of about 14 days developmental age which should have chorionic villi but shows only extreme hypoplasia of the trophoblast.


78 Surface view of the implantation site to show a hemorrhagic mass attached to the abembryonic pole of the implanted abnormal ovum. Similar hemorrhage may however be associated with normal specimens of the same developmental age. Carnegie 7800, Sequence 2. X 8.

79 Profile view of implantation site to show the elevation of the hemorrhagic mass over the implanted abnormal ovum. Carnegie 7800, Sequence 3. X 8.

80 Low-power view of the section through the largest diameter of the abnormal ovum shown in figures 78 and 79. The trophoblast around three-quarters of the ovum is extremely hypoplastic and is markedly abnormal in the other one-quarter where there is some attempt to form villi. Note that the germ disc and the formation of amnion and yolk-sac appear morphologically to be unremarkable. This stage of ovular development would coincide with the time of the patient’s next expected period. The deeidual reaction and hemorrhage within the endometrial gland are normal. Abortion might be imminent on the basis of the deficiency of the ehorionic gonadotropin produced by the placenta which maintains corpus luteum function. Actually it is impossible to predict the precise time of such an inevitable abortion. Carnegie 7800, Section 15-1-3. X
