Poisons
A girl, aged 18, after two days’ illness, was admitted into Guy’s
Hospital. She confessed to having eaten a piece of bread coated with
phosphorus paste. She had great abdominal pain, and died on the seventh
day after taking the phosphorus. A few hours before her death she was
profoundly and suddenly collapsed. The liver weighed 66 ozs. The
outlines of the hepatic lobules were very distinct, each central vein
being surrounded by an opaque yellowish zone; when fresh the hue was
more uniform, and the section was yellowish-white in colour. A
microscopical examination of the hepatic cells showed them laden with
fat globules, especially in the central parts of the liver.
The microscopic appearances are also characteristic. In a case of
suicidal poisoning by phosphorus, in which death took place on the
seventh day, the liver was very carefully examined by Dr. G. F. Goodart,
who reported as follows:--
“Under a low power the structure of the liver is still readily
recognisable, and in this the specimen differs from slides of three
cases of acute yellow atrophy that I have in my possession. The
hepatic cells are present in large numbers, and have their natural
trabecular arrangement. The columns are abnormally separated by
dilated blood or lymph-spaces, and the individual cells are cloudy
and ill-defined. The portal channels are everywhere characterised by
a crowd of small nuclei which stain with logwood deeply. The
epithelium of the smaller ducts is cloudy, and blocks the tubes in
many cases. Under a high power (one-fifth) it is seen that the
hepatic cells are exceedingly ill-defined in outline, and full of
granules and even drops of oil. But in many parts, even where the
cells themselves are hazy, the nucleus is still fairly visible. It
appears to me that, in opposition to what others have described, the
nuclei of the cells have in great measure resisted the degenerative
process. The change in the cells is uniform throughout each lobule,
but some lobules are rather more affected than others. The
blood-spaces between the cells are empty, and the liver appears to
be very bloodless. The portal canals are uniformly studded with
small round nuclei or cells, which are in part, and might be said in
great part, due to increase of the connective tissue or to a
cirrhotic process. But I am more disposed to favour the view that
they are due to migration from the blood-vessels, because they are
so uniform in size, and the hepatic cells and connective tissue in
their neighbourhood are undergoing no changes in the way of growth
whatever. I cannot detect any fatty changes in the vessels, but some
of the smaller biliary ducts contain some cloudy albuminous
material, and their nucleation is not distinct. No retained biliary
pigment is visible.”[309]
