20 New Growth in the Nasal Cavities. 



finally heal williont Icaviiii;- any traces. The hinph vessels, 

 which drain the aft'ected portions, are nsnally much swollen and 

 can l)e felt as tender cords leading from the angles of the 

 month backward, and also down toward the neck. In their 

 neighborliood abscesses are formed here and there, which 

 break open, but heal promptly. The submaxillary Ijmiph glands 

 are always in a condition of acute swelling. Sometimes one 

 also sees nodules on the generally reddened conjunctiva of the 

 eyes. The disease lasts two to four weeks and generally ends 

 in complete recovery. 



Diagnosis. The affection is distinguished from glanders 

 in that the nodules and ulcers appear simultaneously or within 

 a short time over a larger area in great numl)ers and that they 

 heal without leaving any trace. 



Treatment. Irrigation of the nasal cavities with mild disin- 

 fectant and astringent fluids (see page 7) and subsequent 

 applications of desiccating ointments to affected cutaneous re- 

 gions are very serviceable. Also applications of ointments con- 

 taining mercury, iodoform, creolin, or iodin to the affected cu- 

 taneous regions.

Occurrence. Neoplasms are generally rare in the nasal cav- 

 ities. Most commonly are found so-called polyps, more rarely 

 such other neoplasms as myxoma, sarcoma, carcinoma, angioma, 

 osteoma, odontoteratoma, lipoma, ecchondroma ; in the nasal 

 cavities of cattle are also found mucous cysts. A similar clin- 

 ical significance as true tumors have tuberculomata, as they oc- 

 cur rarely in the nasal cavities of cattle in the shape of nodular 

 masses which are scattered over the surfaces, covered with a 

 mucopurulent material and with yellowish spots, (lerspach 

 saw in a horse tuberculous nodules of pea-size alternating with 

 tuberculous ulcers covered with yellowish, dry adherent crusts. 

 Very rarely actinomycomata are found in cattle in the shape of 

 strawberry-like masses in the lower portions of the nasal cavi- 

 ties. 



Symptoms. A tumor growing in the nose usually makes, in 

 proportion to its size, one, rarely both nasal cavities more nar- 

 row, and thereby produces difficulty in respiration, blowing 

 or snoring. According to the degree of stenosis, these s>aiip- 

 toms are observed either during exercise or likewise during 

 rest. If the stenosis is produced by a motile neoplasm, dyspnea 

 and the noises accompanying it are observed only occa- 

 sionally, or the character of the noises changes. If the nasal 

 opening of the affected side is closed the noises cease, while 

 closure of the healthy side increases them and increases dyspnea.
