=Ulcerations= may be catarrhal, with superficial erosions or follicular ulcers; or syphilitic, in the form of the hard and soft chancre; or we may, in rare cases, have the corroding ulcer, described by Dr. John Clarke, and differing from genuine carcinoma only in the absence of an indurated deposit. Morbid Growths. _Fibroid tumors_ are of most frequent occurrence. They are found either imbedded in the texture of the uterus, or protruding from its inner surface into the cavity, or from some part of its external surface. Those projecting into the cavity of the uterus, called also _fibrous polypi_ or submucous tumors, are most frequently met with. Their pedicles are generally situated just below the openings of the Fallopian tubes, although they spring also from the posterior wall and from the fundus, less frequently from the anterior wall, and still more rarely from the cervix uteri. Recent investigations go to show that these tumors are to be classed with the homologous, rather than heterologous productions, and that they are developments of true muscular tissue. To the naked eye this structure varies in some respects; at times they present a concentric disposition of fibres, but more commonly an irregular, wavy appearance, without any uniformity of arrangement, and in the latter case, frequently with cavities containing blood, a dark-colored gelatinous fluid, or a clear serum. Under the microscope, a fibrous structure is scarcely perceptible, but elongated nuclei are seen, imbedded in an amorphous stroma. The vascularity of fibrous tumors varies. The majority are but scantily provided with vessels. The tumors imbedded in the uterine tissue form globular, white, glistening, dense tumors. There may be only one, or they may be numerous, and may vary in size from that of a pin’s head to that of a melon. These growths are subject also to secondary changes; thus we may find abscesses in the very centre of fibroid growths, or they may contain encysted melanotic tumors, or a species of calcification may be developed. Fibrous tumors have not been observed before puberty, but occur, according to Lee and Bayle, most frequently in virgins. =Polypi and Polypoid Growths.= These growths—not to be confounded with the fibrous tumors, as is frequently done—are soft and succulent, and project into the cavity of the uterus, or hang into the vagina. They are attached by a pedicle of greater or less width, to the surface from which they spring, and are covered with the mucous membrane of the part. They are essentially a morbid condition of the structures of the surface, the mucous membrane, the follicles, or sebaceous crypts of the different parts of the uterus.[36] Polypoid tumors may give rise to hæmorrhages. They may become inflamed, suppuration or even gangrene supervening. In this way the pedicle may be destroyed, and the tumor be expelled.
