3. Encephaloid disease or fungoid tumor, differs from scir- 

 rhous cancer chiefly in the great predominance of its transitory 

 or morbidly developed cells over the fibrous and other elemen- 

 tary textures which constitute the stroma (matrix) of the 

 tumor. In carcinomas, the fibrous tissue predominates and 

 gives solidity and firmness to the whole mass. The morbid or 

 cancer cells never tend to develope organized fabrics, but 

 always to disintegration and softening down of the tumor. 

 Their great predominance in encephaloid, therefore, gives the 

 character of brain-like softness and yielding, which is the dis- 

 tinguishing characteristic of this form of "malignant growth. 



Fig. 48 represents encephaloid, from the liver, under the 

 microscope. It appeared wholly composed of cells, which 

 showed distinct nuclei and nucleoli. The cells were mostly 

 roundish or oval, but some were caudate. Acetic acid ren- 

 dered them full and brought the nuclei plainly in view, a. 

 Here and there some nuclei were seen in an amorphous cyto- 

 blastema. 



Although the cells of encephaloid belong to the class of
