92 THE ALIMENTARY TRACT. 
What are the inflammations of the pharynx? 
Catarrhal pharyngitis, croupous pharyngitis and submucous pharyn- 
gitis. The first two forms of inflammation give the changes common to 
its own variety as described before. The submucous pharyngitis is an 
exudative inflammation affecting the submucous coat of the pharynx 
and may result in the formation of an abscess. Ulceration may occur 
in the pharynx from catarrhal or syphilitic inflammation. 
What tumors have been found in the pharynx ? 
Fibromata, carcinomata, adenomata and sarcomata. 
What changes may take place in the esophagus ? 
There may be ulceration from pressure of foreign bodies etc. There 
may be cylindrical or sacculated dilatation, or there may be stenosis 
frum injury or from new growths. 
What forms of inflammation have been observed in the esophagus? 
Catarrhal and also croupous inflammation, giving the same changes 
as regularly occur with these forms of inflammation. 
What tumors have been found in the esophagus ? 
Cysts, papillomata, lipomata, myomata of smooth muscle, carcino- 
mata and adenomata. 
STOMACH AND INTESTINES. 
What are the different forms of inflammation of the stomach? 
Acute and chronic catarrhal gastritis, croupous gastritis and suppu- 
rative or phlegmonous gastritis. 
What changes are produced in the first two forms ? 
In acute catarrhal gastritis the structural changes if the mucous 
membrane are very slight. The mucous membrane is covered with 
mucus and there may be a very slight exudative inflammation in it. 
In the chronic form there is a thick layer of mucus coating the 
mucous membrane. The wall of the stomach may be thickened or 
thinned and the stomach may be of normal size or dilated, or smaller 
than normal. The cells lining the gastric tubules are degenerated 
and may be broken down, the tubules are atrophied, or may be dilated 
into cysts. The connective tissue between the tubules is infiltrated 
with cells. 
Give the lesions associated with the two latter forms of gastritis. 
The croupous form is rare and gives the same changes in structure of 
the affected part as the same form of inflammation does elsewhere. In
