194 Otlu'i- Diseases Similar lo Stomatitis.

It is not impossible that some of the forms here enumerated belong to the 

 contagious papulous form of stomatitis (see page 190). 



As to tlie clinical picture, the aphthouslike diseases may, for con- 

 venience sake, l)e divided into two groups. In one group the buccal 

 mucosa only or possibly also the integument of the muzzle is involved. 

 The mucosa of the hard palate, the gums, more rarely the sides and the 

 tip of the tongue, the inner surface of the lips and of the cheeks, present 

 grayish-white to grayish-brown pseudomendiranous deposits on a more 

 or less reddened surface, or in other cases, round, intensely red erosions 

 up to the size of a silver quarter, the base of which is partly covered with 

 a grayish-red, or yellowish, thin, flaky or thicker deposit. In some 

 cases one also sees numerous pinhead hemorrhages in the papillae of the 

 mucosa. In some animals the muzzle shows lenticular prominences and 

 erosions of the epithelial covering (Fig. 30). Only exceptionally does 

 the disease assume a febrile course and lead to salivation and disturb- 

 ances in the ingestion of food. 



The clinical picture of the second group is characterized by the 

 simultaneous affection of the buccal mucosa, of the integument of the 

 muzzle, of the integument of the extremities, and of the udder. With an 

 elevation of temperature, the appetite is diminished or entirely lacking. 

 Profuse salivation appears and smacking noises are heard just as in 

 foot-and-mouth disease. The mucosa of the mouth is intensely reddened 

 and covered with corrugated, diffuse, pseudomembranous deposits, espe- 

 cially on the hard palate, the gums, the inner surfaces of the lips. The 

 pseudomembranes come off in shreds and the erosions heal in a few 

 days. Lenticular yellowish-red or grayish nodules or crusts with a cen- 

 tral depression appear on the muzzle and exceptionally on the nasal 

 mucosa. Similar nodules sometimes appear on the mucosa of the mouth. 

 The lower extremities show evidences of a dermatitis which is similar 

 to that seen in clover diseases (see under this heading) ; on the skin 

 of the udder, nodules of the size of a lentil with several vesicles and 

 subse(|uent crust formation were seen by Kantorowicz. 



Tlie disease always takes a favorable course either within a week, 

 or in the variety last described within two to three weeks, slight emacia- 

 tion having become manifest in the meanwhile. 



The differential diagnosis has to consider foot-and-mouth disease. 

 It is distinguished by the simultaneous vesicular eruption at the ends of 

 the extremities and on the ])uccal mucosa, the involvement of the back 

 of the tongue and the absence of the peculiar pseudomembranes on the 

 mucous membranes of the mouth. In the forms of stomatitis here de- 

 scribed, the contagious character is usually absent, also the involvement 

 of the extremities and of the udder. 



Treatment becomes necessary only in the more severe forms with 

 dermatitis at the extremities. The principles of the treatment are the 

 same as those in catarrhal stomatitis (see page 185). Most cases end in 

 recovery without any treatment at all.
