What is a Tnycofibroma ? 



The mycofibroma or botryomycoma is a form of fibroma 

 apparently due to the infection of the tissues by botryomyces, 

 although V. A. Moore's (Cornell) researches, recently made, 

 tend to show that it is not a specific infection, but most 

 likely due to the invasion of the tissues by any one of several 

 microorganisms, especially the micrococcus pyogenes aureus. 



What is a heloid ? 



A proliferation of fibrous tissue originating in a pre- 

 existing scar, most commonly seen in the flexion surface of a 

 joint, as the fetlock, for instance. 



What is a compound fibroma ? 



It is a tumor composed not only of fibrous tissue, but 

 also of tissue peculiar to another tumor variety. Thus, when 

 made up of fibrous tissue and muscular tissue, it is termed a 

 fibromyoma; when mixed with nerve tissue, fibroneuroma; 

 when mixed with mucous tissue, fibromyxoma, etc.
