General surgical pathology and therapeutics, in fifty lectures : a textbook for students and physicians. tion of this cyst-development to the sarcoma (the natureand course of the disease is not much influenced by the former) variesgreatly in these, as in all cystosarcomata. Mammary and cysto sarcomata are not very rare, but are far lessfrequent than the cancers of the breast, which we shall hereafter men-tion. The disease is most frequent in young married women, butalso occurs shortly before puberty—rarely after the fortieth year oflife. The growth of these tumors is very slow, and is painless beforethey become large; later, however, they are accompanied by piercingpains; as the tumor may grow as large as a mans head, and ulcerate,it may prove very troublesome. Some of these sarcomata have thepeculiarity of swelling, and becoming slightly painful shortly before 628 TUMORS. and during menstruation. In this disease, the general health is notaffected, except that in large ulcerated tumors the patients emaciate,become anasroic, and acquire a suffering look. The course of the dis- Fia. From an adeno-sarcoma of the female breast: a, dilatation of the excretory ducts; b. of theacini, magnified 60 diameters ; c, a dilated acinus of the mammary gland, -with cylindricalepithelium ; intermediate substance resembling granulation-tissue, magnified 350 diameters. ease may vary; there are not a few cases where small sarcomata ofthe breast, which perhaps came after the first confinement, spontane-ously disappeared in the course of time, or else remained for the restof life without doing any harm; but in most cases these tumors growgradually, until they are operated for; if this is not done till late, whenthe tumors have become large, and the women have attained old age,they may become infectious. In young girls and women, when aslowly-growing sarcoma of the mammary gland is extirpated, it doesnot usually reappear. If, however, the sarcoma first appears betweenthe thirtiet
