104 PEINCIPLES OF VETEEINARY SUBGEE7 



Outline the treatment of lymphomata. 



Solitary lympliomata— that is, the swelling of regionary 

 lymph glands — when due to specific infections, are not treated 

 (glanders, tuberculosis, etc.) ; those due to simple chronic 

 nasal catarrh take care of themselves as soon as the catarrhal 

 state is relieved ; those of equine distemper undergo abscess 

 formation and are treated as such. 



The treatment of multiple lymphomata of Hodgkin's dis- 

 ease are not treated surgically, but iodide of potassium or 

 arsenic, with proper dietetic regime, may be tried. 



Sarcoma. 



What is a sarcoma ? 



A malignant tumor composed of immature connective 

 tissue — that is, embryonic tissue. 



Describe the histological structure of this tumor. 



The number of cells are vastly in excess of the basis sub- 

 stance. The cells are either round, spindle, giant cells or 

 endothelial cells ; they have from one to more nuclei ; there 

 is no distinct cell wall, and the stroma consists of an irregu- 

 larly arranged intercellular cement ; in other words, there are 

 no alveoli formed, as in carcinomata. The blood vessels, 

 which are very thin walled or sometimes only represented by 

 spaces, ramify among the cells, not running in the stroma 

 as in carcinomata, because of the absence of any regular 

 stroma. 



How do sarcomata grow ? 



Spasmodically ; now fast, now slow. 

 To what degenerative changes are they subject ? 



Cystic formation, ulceration, hemorrhage, necrosis.
