LIVER. 95 
What are the tumors occurring in the peritoneum ? 
Fibromata, lipomata, angio-sarcomata, carcinomata, sarcomata and 
endotheliomata. 
LIVER. 
What degenerative changes may take place in the liver? 
Parenchymatous degeneration, fatty degeneration, fatty infiltration 
and amyloid degeneration. Pigmentation may occur as a result of 
malarial poisoning. 
What affection of the liver is characterized by an extreme degen- 
eration of the liver cells? 
Acute yellow atrophy. The liver decreases rapidly in size. The 
cells become granular and fatty and soon break down into an indis- 
tinguishable mass in which may be seen fatdrops, pigment granules, 
red and yellow crystals, and amorphous debris. 
What disturbances of circulation may occur in the liver ? 
There may be an anzemia, either general or partial, due either to a 
general anemia or toa shutting off of blood supply from different 
parts of the liver by pressure. Also a hyperemia which may be 
acute or passive. The acute process may be due to high living, 
excessive heat, suppression of menses, etc. The passive process is due 
to-obstruction of the blood current in the hepatic veins. 
Valvular disease of the heart is the most common cause of passive 
congestion of the liver. 
What are the minute changes produced by a chronic hyperemia ? 
In these cases the gross appearance of a section of the liver presents a 
mottled appearance, hence the name “nutmeg liver” is applied to this 
class of cases. As the congestion affects the hepatic veins the central 
veins of each hepatic lobule are dilated, this dilatation extends to the 
capillaries opening into the central veins. The liver cells between the 
swollen capillaries atrophy and become degenerated on account of pres- 
sure. The change of structure develops from the centre toward the peri- 
phery of each lobule, and there is a zone between the degenerated and 
healthy area that contains numerous leucocytes. 
Name the different varieties of inflammation of the liver ? 
1. Acute hepatitis (Abscess of liver). 
2. Chronic interstitial hepatitis (cirrhosis). 
3. Syphilitic hepatitis. 
4. Tubercular hepatitis.
