 been described. 



Angioma. Cavernous angiomata of the wall of the uterus have been 

 described. Eudothelioma is of rare occurrence in the cervix. l 



Adenoma. Between a simple adenomatous hyperplasia of the mucous 

 membrane of the 

 uterus, on the one 

 hand (see Figs. 423 

 and 424), and carci- 

 noma on the other, 

 there is no absolutely

 distinction. But 

 there is a consider-

 growths, to which 

 the name adenoma 

 is properly applied, 

 which lie on the bor-

 distinctly benign and the definitely malignant new epithelial-tissue 

 growths. 



Many epithelial-cell growths of the uterus, while adenomatous in 

 structure, are so distinctly malignant, and are so liable to develop that 

 structural lawlessness characteristic of carcinoma that it has seemed wise 

 to many observers to avoid the name adenoma altogether and class all
