Lesions 439 



Microscopically the lesions consist chiefly of a round-cell 

 infiltration with circumscribing granulation-tissue leading 

 to the formation of cicatricial bands. In the form known 

 as "wooden tongue" the disease runs an essentially chronic 

 course, with the production of considerable amounts of 

 connective tissue. 



But few cases recover, the disease terminating in death 

 from exhaustion or from complicating pneumonia or other 

 organic lesions.
