TUMOURS OF THE VAGINA AND UTERUS. 695 



size of a hen's egg, and cannot be returned, or if returned, soon appears 

 again. The prolapse is commonest during the time of heat, and after 

 successful coitus. 



Heckmann found in the vagina of a bitch a pedunculated polypus, 

 which arose from the right wall, and was removed by ligation. Zipperlen 

 describes a polypus on the cervix of a cow ; Leblanc a similar growth 

 in a bitch. 



£ In cows, the most common growths are cysts, which occur in the 

 vestibule of the vagina, particularly on the left side. They result from 

 blockage of Bartholin's glands, while those occurring close behind the 

 opening of the urethra are due to occlusion of Wolff's duct. Eggeling 

 detected, in a cow's vagina, a sarcoma telangiectodes, which led to death 

 by bleeding during parturition. Ulcerating carcinomata have repeatedly 

 been found both in cows and bitches ; Bang saw carcinoma of the vesti- 

 bulum vaginae in a cow. 



Sand saw severe bleeding from vaginal varicose veins in a mare. The 

 bleeding could not be stopped, and in consequence of progressive anaemia 

 the animal had finally to be slaughtered. 



Gilruth described an epithelioma of the vulva and vagina in an aged 

 cow. The external growth was about 7 inches long and 6 inches wide, 

 implicated both labiae and the lower part of the anus, and extended about 

 8 inches into the vagina. The animal was killed. The pelvic and posterior 

 mesenteric glands contained small, greyish soft nodules (Cadiot and 

 Dollar's " Clinical Veterinary Medicine and Surgery "). 



Apart from tuberculosis, the uterus is seldom the seat of tumours, 

 and still less frequently does it call for surgical treatment on their 

 account. The changes, often described as scirrhous, probably result 

 from endometritis chronica, though polypoid new growths occur, 

 and are sometimes of considerable extent ; Bedenberg found in the 

 uterus of a cow a tumour which weighed between 28 lbs. and 30lbs. 

 Carcinomata and sarcomata have repeatedly been seen in bitches ; 

 Essex found a fibroid of the uterus in a cow. 



In a cow which had suffered from periodical bleeding from the vulva, 

 Eckhard found a fibroma of the uterus, weighing 52 lbs. Gratia, in a cow, 

 discovered a large fibromyoma that had existed for several years, and 

 had repeatedly caused profuse bleeding. As the new growth rendered 

 parturition difficult, it was removed by ligature, but the animal died from 

 acute peritonitis. Von Bockum-Dolffs found tuberculosis of the uterus 

 in a cow which had been regarded as pregnant. The animal was found 

 on slaughter to have general tuberculosis, the uterus being greatly distended 

 with caseous material. 



Symptoms. Tumours of the vagina sometimes appear beyond 

 the vulva during urination, and becoming strangulated, are at once 

 recognised ; their position and extent are detected by palpation. 

 The same is true of new growths within the vagina. They seldom 

 give trouble unless when of large size, and then because they injure 

 the animal's appearance, or interfere with parturition or urination.
