DISEASES OF THE LIPS AND CHEEKS. 
Stockfleth has described a similar disease in cattle, resulting from injuries, 
but this does not extend as in dogs. Most commonly an abscess forms 
in the cheek, and recovery occurs in a few days. The treatment of other 
inflammatory processes should be adapted to their special features. The 
cause must be removed and care taken that the affected part is not irritated 
more than necessary, either by rubbing or by mastication. Attention is 
accordingly required in selecting and preparing the food, and in the 
management of the animal. Complications are treated on general 
surgical principles. In suppurative forms of skin inflammation, diseased 
parts should be promptly removed with the knife. 
Chronic inflammation of the lips and cheeks in oxen is sometimes due 
to actinomycosis. Klepzow, who examined 2,000 slaughtered cattle, 
found actinomycosis of the lips in 5'6 per cent. Several hard, painless 
swellings appear in a line with the molars. The skin covering them is 
r 
at first mobile, but later becomes adherent and finally breaks, a muco¬ 
purulent fluid being discharged from the wound, which is surrounded by 
flabby granulations which readily bleed. 
The cause is infection with actinomyces from the cavity of the 
mouth. 
Treatment consists in early opening of the swellings, drastic curetting 
of the parts and dressing or plugging with tow saturated in tinct. 
iodi. 
Like actinomycosis in cattle, bothryomycosis of the lips and cheeks in 
horses is not uncommon. Small fibrous swellings form, most frequently 
at the points where skin and mucous membrane are coterminous. 
Treatment should be undertaken earlv; it consists in removal of the 
swellings, careful disinfection and suturing of the wound. 
(8.) TUMOURS OF THE LIPS AND CHEEKS. 
( A.) Warts. In dogs and horses the lips are not infrequently the seat 
of great numbers of small pedunculated warts. These new growths occur 
both on the mucous membrane and on the skin, and vary from the size 
of a pin’s head to that of a grain of linseed. Their covering is often 
wanting in pigment, in consequence of which they appear red on the 
surface and are often thought by laymen to be parasites. They are 
almost always found in young animals, cause no particular inconvenience, 
and may disappear after a short time without apparent cause. Attempts 
to inoculate other animals have proved ineffective (Garcia). If mastica¬ 
tion be interfered with, they can be removed with scissors ; but if 
they cause no inconvenience it is better to await their spontaneous 
disappearance. 
(B.) Encysted tumours also occur frequently on the lips of horses;
