Fig. 26. A human placenta at term

To show the cystic degeneration occurring in the “fibrinoid" of a septum separating two adjacent cotyledons. B. L.-i. H., S-34-581.

A. A low power view of two cotyledons separated by a cytotrophoblastic septum whose "fibrinoid” has undergone cystic degeneration. The resultant hematoma at the base has disrupted the blood supply of the cotyledon at the left and caused infarction but has spared the one to the right. X5.

B. A higher powered view of the rectangular area seen in A. Note degenerated septum with recent hemorrhage below. The villi at the left are congested and undergoing early necrosis whereas the ones at the right are normal. X60.
