TUMOURS OF THE VAGINA AND UTERUS.

Treatment consists in operative removal. Pedunculated tumours 

 can be ligatured, and multiple ligation is also the best method of 

 dealing with partial prolapse of the vagina in bitches. Sessile 

 tumours may be removed by enucleation. Tumours lying further 

 forward may sometimes be removed with the ecraseur, cysts are 

 burst by the pressure of the hand ; if necessary, the operation can 

 be repeated, and the base of the tumour cauterised. 



Cadiot and Dollar (" Clinical Veterinary Medicine and Surgery ") 

 describe a case of myxoma of the uterus in a bitch. The swelling projected 

 slightly beyond the vulva, was ovoid, smooth, of fairly firm consistence, 

 and reddish in colour. It measured 5 inches in length and 6 inches in

circumference. Removal by ligature of the pedicle and section on the 

 peripheral side was followed by recovery. 



Miiller treated a bitch with fibromyoma, complicated with prolapse 

 of the vagina, by injecting ergotin (extr. sec. corn. grs. vii., spirit, dil. 

 et glycerin, aa. m. lxxv.) : of this fluid m. xv. were hypodermically injected 

 at the most convenient spot. In four weeks the swelling had greatly 

 diminished, and complete recovery finally occurred, but whether as a result 

 of the injections is not altogether certain. 



Malignant tumours of the uterus are not common in the 

 domesticated animals, and are rarely diagnosed during life. Where, 

 for reasons of sentiment, the owner attaches unusual importance 

 to the animal's preservation, ablation of the uterus may be performed, 

 but the operation is only practicable in small animals. 



Atresia, complete or incomplete, of the neck of the uterus 

 frecpiently renders animals sterile and calls for operation. In 

 incomplete atresia the entrance to the uterus can usually be dilated
