242 Diseases of the Genital Organs 



positive diagnosis of malignancy, with all the risks of ex- 

 tension and of daughter tumors, should not be awaited. 

 Any chronic tumefaction of the testicle sufficient to arouse 

 fear of malignancy should be treated decisively and 

 promptly as malignant. In any case, the function of the 

 testicle is almost certainly destroyed and the ablation of the 

 hopelessly diseased gland is the prudent course to pursue. 

 The removal of one testicle neither destroys nor curtails 

 the reproductive power of the animal. 



The removal of a testicle which is presumably affected 

 with a malignant new-growth should preferably be effected 

 by the covered operation. The skin and dartos are freely 

 incised down to the cremaster muscle or its fascia. The 

 cremaster, its fascia, 'and the peritoneal layer of the scro- 

 tum are kept intact and a separation made between the cre- 

 master and dartos up to the external inguinal ring. The 

 spermatic cord, covered by the cremaster muscle and the 

 scrotal peritoneum, is then securely ligated at a point as high 

 as is convenient or required. It is best to arm a heavy needle 

 with a strong thread and pass it through the cremaster 

 muscle, scrotal peritoneum, and spermatic cord. The needle 

 is removed and the ligature tied about the spermatic cord 

 and cremaster very tightly, in order to make inevitable the 

 immediate necrosis of all included tissues. The included 

 mass is then excised on the distal side of the ligature at a 

 distance sufficient to guard securely against its slipping, 

 generally about one inch. The cavity in the scrotum should 

 then be tamponned with antiseptic gauze and the cutaneous 

 wound closed by sutures. The gauze should be allowed to 

 protrude at the lowest part of the wound, in order to permit 

 drainage. 



Malignant tumors of other portions of the genital tract 

 of the bull are not as amenable to handling as are those of 

 the glans penis and the testicle. They need to be handled 

 according to general principles. 



Malignant tumors of the genital organs of horses are not 

 at all rare. According to my observation, they are com-
