tissue. They are soft, gelatinous and rather rare among 

 domestic animals. Lucel observed a case in the third right 

 teat of a six-year-old bitch. It consisted of an enormous 

 trailing, piriform mass. (Fig. 83). We have observed two 

 cases of melanotic myxoma in cows, both of which were 

 as large as a child's head, clearly pedunculated and located 

 in the umbilical region. They are benign tumors and easily 

 ablated when not diffuse.

cartilaginous tissue. They are hard, unyielding, irregular and 

 sometimes elastic. (Fig. 85>. They develop slowly and 

 rarely generalize. They are found in glands and bones. 

 (Fig. 86). The fact that their generalization is possible 

 must not be ignored. Nocard et al. observed such cases. 

 A case reported by Generali generalized in the lungs, kid- 

 neys and nerve centers after having been extirpated from 

 the teat. The enchondroma, when recognized, should be 

 surgically removed.
