Cases of aberration in the first development and ultimate station of the human
embryo like these, were not known to science (according to Dr. Breschet’s
statement) before the two preceding instances were laid before the profession. I
selected them, therefore, on account of their priority, from among the six cases
collected by that indefatigable and highly gifted anatomist, whom I am proud to
call a very old friend, in his memoirs on “A New Species of Extra-uterine
Pregnancy,” published in the first volume of a very valuable work, edited by
himself, Dupuytren, and others, in 1826, entitled, “Repertoire General d’Anatomie
et de Physiologie.” The facts are singular, yet authentic in all their particulars. It is,
therefore, impossible to deny the existence of another distinct species of
pregnancy, extra muros uteri, in which the fœtus is lodged among the interstitial
elements of that viscus, and has no communication whatever either with the cavity
of it on the one side, or the cavity of the abdomen on the other; unless ulceration or
laceration take place.
We may, therefore, reckon four species of erratic gestation, namely:—
Gestatio Ovarica.
Gestatio Tubica.
Gestatio Interstitialis.
Gestatio Abdominalis.
The design of the parts, the statement of facts, and all the particulars connected
with such cases of gestatio interstitialis, I give on the authority of the respective
authors whose names I have mentioned. It has never fallen to my lot to witness a
single instance of such anomaly in the mode of propagation of our species. Of the
six cases reported by Breschet, the last only fell immediately under his care, at the
Hôtel Dieu, in July 1825.
It is to be remarked, that in all these cases the uterus was found enlarged, its
cavity filled with some adventitious production of variable texture and not always
membranaceous, and the Fallopian tube on the side next to the seat of the
embryoferous tumour invariably impervious. The mother dies from internal
hemorrhage, in consequence of the laceration of the coats of the cyst containing
the embryo. During life menstruation has ceased in some and not in other cases of
this description.
The reader will not fail farther to notice the very great difference which appears
manifest in the drawing of the present plate, and that of the rest of the plates, from
the hand of our artist. Mr. Perry had, in this instance, a very inferior lithographic
delineation of the facts only to copy,—instead of having to imitate nature, as he has
done in every other instance. The consequence has been, that we see but a feeble,
and not always an intelligible, representation of the several interesting points
connected with these two cases, the nature of which has been attempted to be
explained by Breschet himself, and Geoffroy St. Hilaire, in his report to the
Institute of France—but with indifferent success.
