In the Fallopian tubes and the ovaries pathological changes occur as the result of uterine fibroids. The tubes may present any of the forms of cystic change--hydrosalpinx, pyosalpinx, or hematosalpinx--that are caused by salpingitis. It is probable that these diseases are often caused by extension of endometritis. The tubes and ovaries may be much distorted and displaced from the normal position. In some cases the ovary is drawn out into a long cord five inches in length; in other cases it is spread out upon the face of the tumor. Fibroid tumors are liable to several forms of degeneration--calcareous, fatty, myxomatous, edematous, cystic, telangiectatic, gangrenous or suppurative, necrobiotic, and malignant. _Calcareous change_, from the deposit of lime-salts in the fibroid nodules, is an unusual occurrence. It appears most often in women beyond the menopause, and is part of the atrophic changes that take place at this time. (It has occurred in a woman who had been subjected to oöphorectomy for the relief of a fibroid tumor.) I have seen a fibroid tumor the size of the adult head--a solid calcareous mass which could be divided only by means of a saw. The calcareous nodules are surrounded by uterine tissue to which they are but loosely attached. They may be forced out of the uterus and escape at the vulva. They have been called “womb-stones.” _Fatty degeneration_ is a very unusual condition. It has been assumed to take place, as a step preliminary to absorption, in those cases in which a fibroid tumor disappears after labor or from other cause. _Myxomatous degeneration_ is also rare. In it an effusion of mucous fluid takes place between the bundles of fibrous tissue. Sometimes large cavities are formed in this way. In the _edematous fibroid_ the whole tumor is permeated by a serous fluid. This condition is not unusual. It resembles edema in any other part of the body. It is often found in young women before the thirtieth year. _Cystic degeneration_ of fibroid tumors may result from any of the forms of degeneration with softening in which cystic cavities are formed. In some cases _fibro-cystic tumors_ are caused by dilatation of the lymphatics. They have been called “lymphangiectatic fibroids.” An endothelial lining has occasionally been found in the cystic cavities of these tumors. The fluid removed from the cyst-cavities coagulates spontaneously. Such fibroids have frequently been mistaken for ovarian cysts. In the _telangiectatic_ or the _cavernous_ form of fibroid tumor there is an enormous dilatation of the vessels in the new growth. The venous spaces are sometimes as large as a walnut, and are filled with clotted or fluid blood. This change usually affects one part, and not all, of the tumor, which presents the gross appearance of a sponge soaked with blood.
