TUMOBS 103 



How do you treat an angeioma ? 



Their hidden position renders diagnosis and treatment 

 difficult. When they can be reached, they may be punctured, 

 fired, or liquid iron preparations injected into them, taking 

 the precaution to compress the vessels which carry the blood 

 out of the tumor long enough to insure coagulation, as other- 

 wise an embolus might be swept away and lead to compli- 

 cations. 



Ljrmpliatic Gland Tumor— Lymphoma. 



What is a lymphoma f 



A tumor of lymphatic gland structure. 



Where do they develop f 



They originate in pre-existing adenoid tissue. 

 Whatform,s of lymphomata are recognized 9 



1. The metastatic swelling — that is, an inflammatory 

 hyperplasia of the lymph glands as a result of chronic dis- 

 ease of neighboring parts, such as tuberculosis, glanders, 

 actinomycosis, equine distemper, catarrhal states. 



2. Malignant lymphoma. 



Describe the malignant lymphoma. 



The lymph gland or glands undergo hyperplasia of their 

 normal elements. It is peculiar to the disease known as 

 'pseudo-leukemia, or Hodgkin's disease. It is observed in 

 horses, cattle and dogs. The tumors are multiple, painless; 

 the enlargements variable, occasionally of great size ; groups 

 of lymph, glands or those of the whole body may be hyper- 

 plastic ; they may be hard, firm or softish, have the shape of 

 the gland, only materially enlarged. The lymph glands 

 more frequently observable are the intermaxillary, cervical, 

 inguinal, those below the knee, etc.
