TUMORS OF THE VAGINA. 



The vagina is the seat of different forms of neoplasms in the 

 various domestic animals. Thus cystoma, lipoma, adenoma, 

 fibroma, fibro-myoma, sarcoma and epithelioma have been noted. 

 They are essentially surgical and to be dealt with as such. They 

 are mainly important in this connection as inducing a leucorrhoea, 

 which in the absence of careful examination might be mistaken 

 for that of uterine or vaginal infective inflammation.
