TUMORS. 



This metastatic tumor was secondary to a large epithelioma of the back of the hand. The small cells 

 with darker nuclei are the cells of the lymph-node. It shows the epithelial pearls in various stapes of 

 formation. 



The new epithelial cell groups may be large or small, may be sepa- 

 rated by much or little stroma; often form reticular masses (Fig. 194),
