The swelling of the alæ nasi also often extends to the skin of the face,
and firm, rounded cords formed by the swollen lymphatics stretch upward
toward the eye, or the submaxillary glands. Upon the turgid lymphatics
may appear more or less rounded nodules from the size of peas to hazel
nuts, which, unlike the submaxillary glands, tend to soften, burst and
discharge a viscid, glairy, sanious liquid.
At the same time the morbid process is liable to show itself in the
cutaneous lymphatics of one limb, usually a hind one, in the form of
firm cords, with degenerating or ulcerous nodules (farcy buds) and pasty
patches. Or the throat or lungs may become involved, with local
swellings, violent cough, dyspnœa and fever. The swellings of the
cutaneous lymphatics usually follow the course of the veins, in the hind
limbs the branches of the saphena, and extend from below upward, and the
first nodules may be on the fetlock or hock.
_Symptoms of Chronic Nasal Glanders in Solipeds._ The chronic form of
the disease follows an indolent course, and local symptoms are often so
slight or equivocal that the true nature of the malady is unsuspected.
If the patient is well fed and cared for and not overworked, the malady
may run a course of three, five or seven years, and the victim may pass
through many hands leaving infection in every stable it occupies.
Diagnostic symptoms, more or less clear, may be obtained from the
discharge; the lesions of the mucosa and the submaxillary glands.
The _nasal discharge_ may be bilateral, but if confined to one nostril
is strongly suggestive of glanders. It may be profuse or scanty,
continuous or intermittent, of a yellowish, purulent tint, or greenish,
or grayish and with a special tendency to viscidity. In some indolent
cases the nostrils may be clean but if there is any matting of the long
hairs, or adhesion of the alæ nasi, the case is specially suspicious. If
it is sanious, flocculent, or bloody it is all the more characteristic,
and suggests the supervention of an acute attack.
