 ORIGIN. 



a. Common Connective Tissue Type. 



1. Fibroma is a generally innocent growth, consisting 

 essentially of fibrous tissue (Fig. 216). Fibromata are

usually circumscribed, rarely diffused, and are composed 

 of interlaced fibres and cells, like cicatricial tissue. The 

 common fibroid is so dense that in cutting it creaks under 

 the knife. 



Fibromata occur on the trunk and extremities, proceed- 

 ing .from the skin (as elephantiasis tuberosa, etc.), from the 

 subcutaneous and intermuscular connective tissue, from 

 fascia, periosteum, bones, and bone-marrow ; in the uterus 

 and its vicinity, in subserous tissue, in submucous tissue, 

 especially of the nose and throat ; in nerves (as common 

 neuroma and the subcutaneous painful tumor, or irritable 

 tumor, as it is called) ; in glandular organs, as the mammae 

 and kidneys, etc. For the most part fibromata grow very 

 slowly, but they are often combined with other forms.
