Tumors of the ovary are divided into two main groups—(1) non-proliferatingtumors and (2) proliferating tumors. (1) Non-proliferating Tumors The tumors of this group represent errors in the development and regres-sion of the Graafian follicles which result in retention cysts. These cysts are oftwo kinds—those which are produced by abnormal secretion of an atretic follicle,follicle cysts, and those which are consequent on incomplete involution of acorpus luteum. Follicle Cysts.—We have seen in the section on Physiology that only a com-paratively few of the primary follicles with which the ovary is originally endowed 382 GYNECOLOGY come to full maturity. Most of the follicles during some stage of their develop-ment become aborted; the ovulum dies; the epithelium of the membranosa. Fig. 132.—Cystic Degeneration of the drawing of a section of a whole ovary. In the cortex are several small cysts whichmicroscopically proved to be cysts of Graafian follicles. On the left are cysts with only thin parti-tions between them, suggesting how, as they become larger, the partition thins out, ruptures, andallows two cysts to coalesce into one. .. - ? «»-«*i. — « act* «o«i;»oi>o^*°eS >-•*—„ ~S 0?0 S fi J
