ULCEE 75 



According to the quality of the surface granulations, what 

 forms of ulcers are recognised ? 



Fungous, or exuberant, phagedenic, gangrenous, diph- 

 tlieritic. 



In describing an ulcer, what main points are to he considered? 

 Its granulations, edges, depth, surrounding skin, dis- 

 charge, size, shape, seat. 



Describe a healthy ulcer. 



Granulations small, cherry-red and regular ; discharges 

 a limited quantity of laudable pus; its edges slope and are 

 "but little indurated ; its shape is regular, the surrounding 

 skin flexible. 



Describe a fungous ulcer. 



Usually seen after injuries followed by undue contraction 

 of the surrounding tissues, causing an obstruction of the 

 venous circulation here. The granulations rise above the 

 surrounding skin ; they may be large and flabby and bleed 

 easily. 



Describe a phagedenic ulcer. 



It is due to infection by various micro-organisms ; its 

 edges appear as if eaten out ; the surface of the ulcer is 

 ■wanting in granulations, being covered with sloughing tissue. 



Outline the treatment of ulcers. 



In some cases rest is sufficient ; for instance, dogs suffer- 

 ing with ulceration of the tip of the ear are prevented from 

 shaking the ears continuously by placing a hood over head 

 and ears. In other instances, foreign bodies, bits of necrosed 

 bone, cartilage, tendon, must be removed before healing can 

 take place. Then, again, the granulations or the indurated 

 edge may have to be removed by excision, curetting, canter-
