Neumann ex-amined a monolocular ovarian cyst which contained four liters of fluid,and found that the cyst had developed from a Graafian follicle. Thedeposit which formed in the fluid after standing for some time containedepithelial cells of the membrana granulosa and innumerable ova witha distinct zona pellucida. Neumann estimated the number of ova atmany thousands. The majority of simple ovarian cysts undoubtedlyoriginate from embryonic tubular rests. 196 PATHOLOGY AND TREATMENT OF TUMORS. Cysts of the corpus luteum were ascribed by Rokitansky to preg-nancy, but Gottschalk found them also in nullipara. The contents of a. Fig. 108.—Corpus luteum; X 3So. corpus luteum of the ovary without cystic degeneration are shown inFigure 108, which shows the epithelial cells of the follicle artd rem-nants of the blood-clot. Cystic degeneration of afollicle may lead to the formation of cysts as largeas an apple. Nagel has seen them as large as anadults head. Cysts of the corpus luteum (, 110), as well as follicular cysts, are not cystictumors, but are retention-cysts. The parovarium (Fig. 99, /) is frequently theseat of cyst-formation. This structure is an em-bryonic remnant, and consequently it frequentlycontains the essential tumor-matrix. of theparovarium (Fig. iii) are also called cysts ofRosenmijllers organ, because their origin in the broad ligament, inwhich they are situated, corresponds to the seat of these embryonicremains. Vcrneuil, Doran, and De Sinety believe that these aredeveloped in the connective tissue independently of the par
