NEOPLASMS OF THE PHARYNX 129 



Epithelioma.— These are found occasionally in old animals, 

 and occur in the pharynx as a primary condition or may be due 

 to metastasis. The retropharyngeal and submaxillary lymph 

 glands are nearly always involved. This condition has been 

 seen secondary to malignant goiter, having extended to the 

 lymph glands by metastasis and from there to the pharynx. 



Symptoms.— Difficulty in swallowing; fetid odor from the 

 mouth; often profuse salivation. Direct examination shows 

 the presence of an ulcerated enlargement on the pharyngeal 

 mucosa. The general condition is in most cases disturbed. 

 Emaciation, especially when due to metastasis; loss of appe- 

 tite. A small portion of the enlargement should be obtained 

 and examined microscopically to confirm the diagnosis. 



Treatment.— No satisfactory treatment can be given.
