Cross-section shows a whitish dense homogeneous connective-tissue substance. Oftenthe tissue is softened by edematous infiltration of the lymph-spaces, which,microscopically, gives the appearance of myxomatous tissue. The edematousinfiltration may be so extensive as to form cystic cavities filled with clearcolorless fluid. Occasionally hemorrhagic areas are seen. NEW GROWTHS 351 Muscle-fibers have been demonstrated by good authorities in these tumors,but their presence is rare. Diffuse fibromata may grow to a very large size. They are characterizedeven when of moderate size by causing ascites, though in what way this isbrought about is not known. Pfannenstiel ascribes the ascites to a chemical. Fig. 151.—Round-cell Sarcoma of the power. The upper part of the drawing shows the tumor, characterized by its round cellslying close together. There are many blood-vessels scattered through it. The light band is part of acorpus albicans and at the bottom is a small area of normal ovarian stroma. irritation of the peritoneum. Schauta considers it to be due to pressure andstasis of the blood-vessels of the parametrium. The diffuse fibromata may undergo sarcomatous degeneration. Sarcoma.—Sarcomata of the ovary are rare tumors. They may originateas a malignant growth, or they may represent a degeneration of a about one-fourth of the cases reported they occur bilaterally. They closelyresemble ovarian fibromata, and can often be distinguished from them onlyby the microscope. Ascites is always present, but this is not a special mark 352 GYNECOLOGY of malignity, because it is usually associated with all solid tumors of theovary. The sarcomata have an ear
