Fig. 73. Abnormal Implanted Ovum

Section through largest diameter of specimen about 9 days seen in figure 71. Although there is a germ disc and amniotic cavity (fig. 72), there is essentially no development of the chorionic cavity. This defect, together with the laminar rather than the circmnfcrential arrangement of syncytio- and cytotroplioblast, makes this a pathologic ovum. It is inconceivable that it could have developed much further although it is impossible to predict the precise type of pathologic abortns that would have been produced by this ovum. Carnegie 8370, Section 6-3-5. X 100.
