Gynecology . Fig. 147.—Colloid Carcinoma of the Ovary. (Metastatic.)High power. This shows the large cells with the eccentrically placed nucleus characteristicof Krukenbergs tumor. When cut in the right plane, as in the lower right and middle parts of thedrawing, they have the appearance of a seal ring. The benign tumors are represented by the fibromata, which appear eitheras small circumscribed growths or as diffuse neoplasms forming large solidtumors. The circumscribed fibromata represent a local hyperplasia of the ovarianstroma, which in some cases can with difficulty be differentiated from

Its contents consist of yellowish, greasy material containing hair. Thethree cavities below are small follicular cysts and the one above to the left is a corpus luteum. rimMTCT COUCSEL Fig. 149.—Dermoid low power. Section of the small dermoid cyst shown in the last drawing. This shows theso-called plug of the dermoid cyst extending into the cavity. It is covered with stratified squamousepithelium under which are sebaceous glands and hair-follicle. A hair-follicle can be seen to the leftof the middle of the plug near its surface. This is a very early stage in the development of a dermoidcyst. They are seldom found so small. 349 350 GYNECOLOGY growth is near the surface, and appears as a tuberous or papillary wart-likeexcrescence. Another form of circumscribed fibroma has its origin in a corpusluteum. These tumors have a definite capsu
