These are somewhat rare in the domestic animals, yet they have been met
with in the form of cysts, fibroma, fibro-myoma, sarcoma, and carcinoma.
In a number of cases the nature of the tumor has not been clearly made
out. Mangot saw a mare with two pediculated uterine tumors having an
aggregate weight of 12 lbs. These were expelled with much straining and
suffering. LaMaitre and Rodet record other cases. Stockfleth describes
multiple pediculated fibroid tumors in the womb of the cow. Cysts have
been especially seen in the cow and bitch, and carcinoma in the bitch.
_Symptoms._ These may for a length of time be overlooked, though
breeding animals usually fail to conceive. Then a slimy, muco-purulent,
serous, bloody or fœtid discharge may escape habitually from the vulva,
smearing the tail and hips and collecting on the floor. If the os is
sufficiently patent to admit the hand vaginal and uterine exploration
will detect the tumor. In other cases it may be felt by rectal
examination.
_Treatment_ is essentially surgical and will consist in dilatation of
the os, and the removal of the tumor by twisting, ecraseur, or curette,
and with careful antiseptic precautions before and after. In malignant
tumors in the uterine walls it may be expedient to remove the entire
organ.
