CYSTOMA. 195 Sometimes the epithelial cells undergo myxomatous degeneration(Fig. 107). Hydrops of the follicles of the ovary is usually a symmetrical affec-tion occurring in both ovaries at the same time. Follicular cysts of theovary seldom result in the formation of large tumors. It was formerlybelieved that most of the simple ovarian tumors resulted from disten-tion of pre-existing Graafian follicles by proliferation of the epitheliallining. That this is not the case is now generally admitted, but thatoccasionally an ovarian cyst may have such an origin cannot be Fig. 107—Follicular cyst of ovary with myxomatous degeneration; X 50 (after Pozzi): ^,^, loose myxomatous tissue toward the interior of the cyst; B, B, dense myxomatous tissue toward the external surface. If in a Graafian follicle a matrix of embryonic epithelial cells shouldexist, we can readily understand that the follicle would become thecyst-wall, while the matrix would furnish the contents. 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 i
