Tumors of the Ovaries 159 



According to this authority, ovarian tuberculosis does not, as 

 a rule, cause nymphomania or produce other symptoms during 

 life beyond sterility, which may be further identified by palpa- 

 tion of the glands, when they may be found enlarged and nodu- 

 lar. A further aid in diagnosis may be secured by the tuber- 

 culin test. The affection is beyond remedy. 



4. Tumors of the Ovaries are somewhat rare in domestic 

 animals bnt are found, occasionally, in all species. 



They may be malignant in character and tend to acquire large 

 size before their presence is suspected or discovered. There are 

 sometimes seen adenoid tumors of great size. In the museum of 

 the New York State Veterinary College is an adenoid ovarian 

 tumor from a sow, weighing 38 pounds. Becoming sterile, she 

 was fatted and upon slaughter the immense tumor was dis- 

 covered. Cystic tumors are occasionally seen of immense size, 

 especially in the mare. 



Ovarian tumors tend constantly to cause sterility with or with- 

 out nymphomania. A tumor of one ovary constantly tends to 

 inhibit ovulation from the other gland. It is usually either the 

 sterility or accompanying nymphomania which attracts attention 

 to the animal and leads to an examination per rectum or vagi- 

 nam, which discloses the presence of the tumor. 



Tumors of the ovary are to be identified by their location, the 

 absence of the normal ovaries and the presence of the tumors to 

 which the corresponding uterine cornua lead and are attached. 

 The ovarian tumor may contract extensive and firm adhesions 

 with the walls or viscera of the abdomen or pelvis and thus com- 

 plicate the question of diagnosis. Its true character is then to 

 be determined by tracing along the uterus, cornu and oviduct to 

 the ovary and thus indentifying it by its relation to the uterus. 

 We have observed the tumor displaced by such adhesions, so 

 that it occupied a quite abnormal location. If essential to a cor- 

 rect diagnosis, an exploratory incision maj' be made through the 

 vaginal walls in the mare or cow or through the abdominal walls 

 in the smaller animals. If discovered while it is of operable 

 size, it should be promptly removed. When involving one 

 ovary only, the successful removal of the tumor will usually re- 

 store to functional activity the remaining normal gland.
