672 TUMOURS OF THE TESTICLE AND EPIDIDYMIS. 



showed numerous fistulous openings communicating with abscesses 

 containing caseous pus ; the two testicles weighed nearly 20 lbs. 

 The horse's testicle, affected with medullary cancer, which Puntigam 

 described, weighed 13 lbs. 



Symptoms and course. One or both testicles slowly increase 

 in size, the swelling appearing painless. Sometimes the surface 

 of the testicle retains its smooth character, sometimes it appears 

 lobulated or knotted. The swelling may become very considerable ; 

 at Alfort a horse was seen that had a testicle weighing 20 lbs.

Malignant new growths often spread to the spermatic cord, 

 causing it to swell and become hard, uneven, or lobulated. Where 

 carcinomata exist, the lymph glands of the lumbar region also become 

 swollen, and in the case of carcinoma of the testicle shown in Fig. 441 

 they were so greatly enlarged as almost to prevent the hand passing 

 into the abdominal cavity. Provided new growths remain confined 

 to the testicle, recovery follows castration, which, so long as it still 

 appears practicable, should not be delayed if the swelling rapidly 

 increases, even if the spermatic cord is already affected. 



Treatment. In such cases castration is the only resort, and 

 even where the growths are of a benign character it is to be 

 recommended if they have attained a large size. As the spermatic
