Sometimes chronic adenitis follows the acute form; at times it occurs 
at once, either under the influence of specific diseases (glanders, tubercu- 
losis, carcinosis), or as consequence of a sub-acute or chronic inflamma- 
‘tion. The glands of a same group become hypertrophied and remain 
‘independent (simple adenitis), or they gather and unite into a single 
‘mass (adenitis and periadenitis). 
In general, chronic adenitis are little painful. They have a great ten- 
dency to last, and when the affection which has promoted. them has dis- 
appeared, it takes a long time for them to disappear. Slow resolution ‘is 
not their only termination ; sclerosis is frequent ; an acute return may bring 
‘Suppuration. ‘ 
The treatment must, first of all, look after the causal lesion. In pro- 
‘portion as the wounds of the legs cicatrize, the glands of the axilla or of 
the groin resolve. Similarly, the maxillary gland diminishes in size when 
‘the purulent collection of the sinuses goes toward recovery. Local treat- 
ment has little efficacy. Blisters have been recommended, napolitan 
ointment, tincture of iodine, iodurated pomatum. If these are not suc- 
cessful, superficial or deep cauterization deserves trial. Extirpation of 
the indurated glands has been little performed in animals. We only use 
it to establish the diagnosis in specific adenitis. In all cases, iodine of 
‘potassium internally will help. 
Suppuration of chronic adenitis is treated like that of acute: incision 
cand antisepsy.’

TUMORS. 
Primitive tumors of glands are extremely rare. Almost always secondary, 
‘they generally accompany epithelioma and carcinoma, sometimes sarcoma 
‘or enchondroma. In cancer, the glands, run through by the lymph of the 
_affected ground, are always suspicious. Generalization begins at the 
‘nearest gland, that which collects the lymphatics of the primitive 
‘focus; hence it spreads little by little; and frequently true neoplastic 
1Dr.‘F. S. Allen has recorded two cases of chronic adenitis successfully cured by 
the removal of the enlarged gland. In one instance, microscopic examination 
‘proved it to be a small spindle celled sarcoma. The whole tumor weighed eight 
-ounces. In the other, the growth weighed only four ounces. Microscopic examin- 
-ation showed it to have been originally lobulated, with hollows at intervals and at 
“points containing small abscesses. It proved to be a lymphatic gland in a hypertro- 
phical condition undergoing an irregular process of regeneration. American Vet.
