Tumors of the Pharynx. 85 



themselves and hang by a pedicle (see pharyngeal polypi). The 

 same is true of the melicerous cyst which originating in an ob- 

 structed mucous or salivary duct projects as a mass as large as 

 a hen's or a pigeon's egg into the fauces or pharynx. 



Symptoms. There are symptoms of intense sore throat with 

 stertor continuous or intermittent, increasing to dyspnoea at 

 intervals or on exertion. In case of pediculated tumors these at- 

 tacks correspond to the displacement of the tumor into the glottis. 

 Deglutition is difficult or impossible, liquids or even solids re- 

 turning through the nose, mixed with mucus and at times tinged 

 with blood. Nasal discharge and ptyalism are present. 



In cattle pharyngeal tumors may be of the same nature as 

 mentioned for the horse, but they are far more frequently lymph- 

 adenoma, and above all tubercle or actinomycosis. Zimmer 

 found that of seventy-three such tumors fifty-four were actino- 

 mycosis. 



The symptoms are wheezing breathing, cough, nasal discharge 

 ptyalism, bleeding from the nose, foetid breath, difficult degluti- 

 tion, attended by cough and rejection of the ingesta through the 

 nose, and the presence of a solid body in or on the pharynx 

 which may be manipulated from without or within and tends to 

 increase in size. 



In dogs there are the same general symptoms with vomiting. 

 The vomited material is usually remasticated and swallowed. 

 The swelling in the pharynx can be felt from without, or seen 

 through the open mouth. The tonsili are usually enlarged. 

 Pressure on the pharynx or gullet produces instant regurgitation. 



Treatment consists in the removal of the tumor when possible. 

 Malignant growths and multiple tumors are not favorable for 

 treatment. Actinomycosis can be treated throughout by iodides, 

 •or these may supplement the surgical measures. In the short- 

 faced animals an ecraseur, or a wire-snare passed through a tube 

 may be employed. (See pharyngeal polypi.)
