OVARIAN PREGNANCY 
condition. In the subsequent fixation and hardening it unfortunately 
became somewhat distorted, so that it was impossible to obtain a single 
section of the entire gland and the interesting structures it contained. 
Even under the most favourable circumstances however, the great mass 
of hardened blood clot proves an insuperable obstacle to perfect sectioning 
in specimens of this kind, and it is practically impossible to get entire 
sections. It was therefore necessary, as it has been in all other cases 
described in the literature, to examine separate slices through the ovary 
and make a reconstruction therefrom. 
NAKED-EYE DESCRIPTION OF THE SPECIMEN. 
The Fallopian tube appeared to be slightly thickened and congested, 
but was in other respects normal. Subsequent microscopic examination 
revealed slight oedema of the subperitoneal tissue at some places, but the 
mucous membrane presented quite a normal appearance and showed no 
decidual changes. There was no adhesion either of the ampulla or of 
the fimbriated end of the tube to the ovary. The ovary was considerably 
enlarged, chiefly in an axis running from the free margin to the hilum. 
It was somewhat sharply marked off into two portions in this axis. The 
portion next the broad ligament was of about normal size, and presented 
the appearance of a healthy ovary of a woman in the child-bearing period. 
The surface was fairly smooth, free from cicatrices, and there was no 
indication externally of a corpus luteum. 
The posterior portion of the gland, corresponding to the haemorrhagic 
mass mentioned above, was directly continuous with the other, but 
sharply delimited from it by change of colour. While the greater part of 
the mass appeared to consist of blood clot, the base of the clot, and 
a considerable portion of its circumference, was bounded by blood- 
infiltrated ovarian stroma. The blood clot was thus obviously protruding 
from a rent in the surface of the gland, and rather towards the lower end 
of the clot was a small fissure between the lips of which projected a mass 
of villi which proved to be one end of a young chorionic vesicle.
