DISEASES OF THE MALE ORGANS OF GENERATION. 315 



ABSCESS. 



These form from too rapid closure of the wound. They may 

 be prevented by carefully introducing the finger in the wound. 

 If they have formed, a free incision should be made into the 

 cavity and the abscess attended to. 



CHAMPIGNON. 



This consists of an indurated condition of the end of the cord, 

 of a tumefied character, varying in size and extent and slow in 

 growth. It may extend as far up as the upper inguinal opening, 

 or beyond it. It is in some cases as large as a man's fist, and 

 sometimes occurs on both sides. 



It often follows the operation by clamps. I have never seen 

 it follow the operation by ecraseur. When called to operate on 

 a champignon, I have always found, on gaining a history of the 

 case, that the animal was castrated by the clamp method. I 

 think it is due to the weight of the clamps pulling on the cord, 

 or from pulling while removing them. In more than three thou- 

 sand horses that I have castrated with the ecraseur I have never 

 known of a case of champignon following; nor have I ever been 

 called upon to remove a champignon where I could trace it to 

 the use of the ecraseur. 



Symptoms. — It develops itself at the cut extremity of the cord 

 as a granulating mass, or a red color varying in size, its growth 

 allowing the cicatrization of the skin to progress in such a man- 

 ner that it forms a point of attachment from which the tumor 

 seems to proceed. There may be swelling of the parts, and the 

 animal travels stiff in the hind legs. Fistulous tracks may be 

 seen on the surface of the scrotum. If the parts be examined 

 the tumor can be easily felt. The tumor may extend as high up 

 as the sublumbar region; in such cases the exact nature of the 

 growth can only be ascertained by an examination per rectum. 



Treatment. — The best method of removing the tumor is by 

 the use of the ecraseur. An incision is to be made parallel with
