SALIVARY GLANDS. 97 
What are the degenerative changes? 
Atrophy, fatty degeneration, fatty infiltration and amyloid degenera- 
tion. 
What tumors occur in the pancreas ? 
Carcinomata cysts, due to a dilatation of the pancreatic ducts. Con- 
cretions of carbonate and phosphate of lime are frequently found in the 
pancreatic ducts also. 
SALIVARY GLANDS. 
What forms of inflammation have been noted in the salivary 
glands? 
Acute and chronic. The chronic inflammations lead to a formation 
of new connective tissue; that is, it is of the productive type of inflam- 
mation. The acute inflammations are of the exudative type. The 
affected gland is infiltrated with leucocytes, and the gland cells may be 
swollen and broken down. Abscesses may be developed. The acute 
glandular inflammation called “mumps” usually affects the parotid, 
although the submaxillary gland may be affected. 
What changes may occur in the ducts of salivary glands? 
They may become inflamed from the presence of foreign bodies, or 
of concretions of lime salts. They may become occluded and widely 
dilated and filled with salivary fluid. In this manner ranulz are 
formed. 
THE DUCTLESS GLANDS. 
What tumors have been observed in these glands ? 
Fibromata, chondromata, sarcomata and myxomata. Most often 
the tumors developed in these glands are of the mixed types, composed 
of several of the above in varying proportions. 
THYROID GLAND. 
What changes may occur in the thyroid? 
It may be hyperzemic or be the seat of hemorrhages. Simple inflam- 
mations, either acute or chronic, are rare, as also are the syphilitic and 
tubercular forms of inflammation. The gland cells may undergo 
colloid degeneration and thus the gland alveoli become filled with 
colloid material. Amyloid degeneration of the gland or of its vessels 
is rare.
