THE REPRODUCTIVE ORGANS OF THE FEMALE. 



be remembered, however, that the primary lesion is a true new formation 

 of glandular tissue, and not, as in the case of most cysts, a transforma- 

 tion, by retention or otherwise, of pre-existing structures. 



The growth primarily consists of a fibrous stroma in which are tubu- 

 lar follicles lined with cylindrical epithelium glandular type. Or, in 

 some cases, it consists of papillary outgrowths from a fibrous stroma, 

 which are covered with cylindrical epithelium papillary type. 



Glandular Cystadenoma. There is, as above stated, a marked ten- 

 dency, in this form of adenoma, to dilatation of the follicles by a semi- 

 fluid material, and the formation of cysts. There may be a number of 

 follicles equally dilated, so as to form a number of cysts of moderate size 

 (Fig. 450) ; or a few follicles are greatly dilated to form a large multilocu- 

 lar cyst with but few compartments (Fig. 448). The walls of the cysts 

 may fuse together and be absorbed, so as to form one large cyst divided 

 by incomplete septa unilocular cysts. The stroma in which the follicles 

 and cysts are embedded may be largely developed or very scanty.

The walls of the larger cysts are composed of fibrous tissue which is 

 dense in the outer layers, more cellular in the inner, upon which the 

 epithelium is placed. They may be thin and membranous, or there is 

 upon their internal surfaces an intracystic growth composed of a fibrous 

 stroma and tubular follicles. These secondary follicles may also be filled 

 with fluid and form larger and smaller cysts. The intracystic growths 

 may be so large as to fill up the original cysts. Sometimes the intracystic 

 growth presents very little dilatation of its follicles, so that the entire 

 tumor has more the character of a solid growth than of a cyst.
